There is limited literature available assessing the performance of CFR-PEEK, specifically as an implant material for arthroplasty systems. Nevertheless, available studies strongly support CFR-PEEK as a promising and suitable material for orthopedic implants because of its biocompatibility, material characteristics, and mechanical durability.

The ongoing development and improvement of orthopedic implants requires much attention as surgeries performed to treat traumatic injuries and joint diseases, along with their associated complications, are highly prevalent. For example, knee osteoarthritis OAa chronic degenerative joint disease, is very common among people over the age of 60 years.

As a result, new implants made of innovative materials are being introduced and evaluated with the goal of improving implant survival rates and reducing the associated burden of revision surgery.

Carbon-fiber-reinforced polyetheretherketone CFR-PEEK has historically been used in spinal cages, bone fixation screws, and cardiac and neurological leads.

TenCate claims more than 40 years of experience in developing thermoplastic composites. Its Cetex brand is well known for prepreg and preconsolidated laminates also called organosheet but also extends to bulk molding compound BMC as well as unidirectional UD and woven tapes.

When I asked TenCate about this, Dr. Note that actual temperatures used when processing these composite tapes may be higher, but TC LM PAEK is still attractive due to its much lower melt point. It uses the PAEK polymer from Victrexand he points out that bythe TC material had already been used in a demonstration aircraft structure.

Airbus Nantes exhibited a fuselage panel with integrated stiffeners at the Paris Air Show. Unger says no, they are all roughly the same. There are two key factors : tape quality and how well the matrix resin and fiber are distributed in the UD tape. This consistency is also important for thermoplastic welding processes and in-situ consolidation. This last point was demonstrated in a laminate-to-laminate comparison.

We then consolidated this laminate using vacuum bag only in an oven.

We achieved the same consolidation properties as in the PEKK 2-step panel. De Vries agrees, noting there is still a noticeable gap between ISC AFP rates and processes in which consolidation is completed in a second step.

Now the goal is to build the technology readiness level. The database is to be released early next year, and this material was chosen because of its mechanical properties and ease of processing. Tokyo, Japan is now rebranded globally as Teijin Carbon, with three major subsidiaries:.

Standard CF sizing must be removed due to the high processing temperatures required for thermoplastics. We see this now moving to larger, more structural parts produced with a mix of AFP laminates followed by consolidation via stamping.

And how robust is the process? The supply chain is growing. It is trademarked as X-CCM by xperion Performance Polymer Composites Markdorf, Germanythe company that initially developed and commercialized the process over two decades ago. X-CCM offers high-quality thermoplastic composite laminates using a fast, quasi-continuous process.

CCM is great for cost but the cross-section needs to remain constant. We have a very sleek process for consolidated TPC parts — there is no vacuum bagging, and we can handle thick laminates of 60 plies and beyondmm in thickness. What kind of parts does X-CCM target? As part of this continued push toward higher volume production, Teijin is focused on reducing tape material cost and increasing capacitysays Canart.

Specifically, de Vries at NLR had said:. We have modified our lines for this thickness and also up to. And what about tape quality? The time and speed of melting is so different for the different resins and processes.

We are supporting further development in a variety of areas, including the polymer systems and the architecture of the tapeincluding the surface. In a statement submitted by Solvay, the company asserts that these polymers are produced at industrial scales that will allow consideration for large-volume aerospace composite applications and can be used to produce high-quality prepreg.

Therefore, it believes that selection of which thermoplastic matrix to use for a given application will be driven by customer preference. Factors affecting that choice include temperature performance, mechanical performance, part fabrication processing, material database availability and workforce experience, to name a few. So for thermoplastics, as in all other composites, the choices in materials and processes are not limited.

In fact, they seem to be expanding. Which will gain ascendancy in future aircraft production? That remains to be seen.Suppliers of thermoplastics and carbon fiber chime in regarding PEEK vs.

Typical is the reaction of 4,4'-difluorobenzophenone with the disodium salt of hydroquinonewhich is generated in situ by deprotonation with sodium carbonate.

PEEK is a semicrystalline thermoplastic with excellent mechanical and chemical resistance properties that are retained to high temperatures. The processing conditions used to mold PEEK can influence the crystallinity and hence the mechanical properties. Its Young's modulus is 3. The thermal conductivity increases nearly linearly with temperature between room temperature and solidus temperature. It is soluble in concentrated sulfuric acid at room temperature, although dissolution can take a very long time unless the polymer is in a form with a high surface-area-to-volume ratio, such as a fine powder or thin film.

It has high resistance to biodegradation. Because of its robustness, PEEK is used to fabricate items used in demanding applications, including bearingspiston parts, pumpsHigh-performance liquid chromatography columns, compressor plate valvesand electrical cable insulation. It is one of the few plastics compatible with ultra-high vacuum applications. PEEK is considered an advanced biomaterial used in medical implantse.

PEEK is finding increased use in spinal fusion devices and reinforcing rods. It is extensively used in the aerospace, automotive, and chemical process industries. In the range of its melting temperature it can be processed using injection moulding or extrusion methods. It is technically feasible to process granular PEEK into filament form and 3D printing parts from the filament material using fused deposition modeling — FDM or fused filament fabrication — FFF technology.

In its solid state PEEK is readily machinable, for example, by CNC milling machines and is commonly used to produce high-quality plastic parts that are thermostable and both electrically and thermally insulating. PEEK is considered a high-performance polymerthat is to say, its high price restricts its use to the most demanding applications only.

PEEK is not traditionally a shape-memory polymer ; however, recent advances in processing have allowed shape-memory behavior in PEEK with mechanical activation. This technology has expanded to applications in orthopedic surgery.

From Wikipedia, the free encyclopedia. Redirected from PEEK. Retrieved 23 April Polymers, High-Temperature.PEEK fibre is a durable fibre with a high tensile strength, which is widely used in wire harnesses and hose braiding applications.

The lightweight material has superior friction and wear properties. The high tensile strength, combined with the light weight of PEEK fibre, makes it an excellent choice for many applications, including Aerospace. PEEK fibre can be used to create a braided sleeve or as an additional jacket which is both stretchable and flexible. The woven material can be placed over an existing cable assembly in order to protect against abrasion and additionally offers an improved chemical wear resistance.

It is known for its impressive durability in punishing environments. Glass and carbon reinforced grades are among the strongest of all thermoplastics at room temperature and unfilled grades are highly resistant to some of the most chemically aggressive environments including high-pressure steam. Put simply, it refers to the chemical structure of the polymer although most polymer scientists identify PEEK as being part of the broader family of ketone polymers called polyarylether ketones PAEKs.

Regardless of the specific chemistry it is the polyketone chemical structure that makes PEEK so formidable in so many environments. What is it about PEEK that makes it a natural fit for so many engineering applications? Chemical resistance, temperature reliability and compressive strength make it suitable for seals, valves, back-up rings and insulators.

High strength and stiffness for applications demanding strength, wear and abrasion resistance and broad based chemical resistance. Because PEEK can either be injection molded or machined into components, some insight into both processes bears mentioning. To be clear upfront, neither process is clearly superior in all instances. Process selection is something project engineers will need to study closely, and something that should be discussed with component suppliers.

This is the most efficient and fastest route to making parts provided the tooling investment is justified. Machining, on the other hand, uses stock shapes and machine shops that mirror the route most metal parts are produced.

A bar of PEEK rod can generally be machined into bushings or bearings often within a few days for hundreds of dollars meaning speed and flexibility are unmatched. The properties of extruded shapes offer the highest stiffness and greatest toughness and in general the most reliable performance.

Machining PEEK is the preferred option in most high precision applications. This includes when production runs involve lower volumes especially runs under 5, partswhen larger components need to be produced and when toughness and impact strength are major priorities.

In short, machining works best when the components need to offer excellent mechanical and wear properties.

Again, there is no clear winner between the two processes but there are situations where one offers a major advantage. Injection molding PEEK is the better choice when producing complex parts usually more than 10, during a single runas injection molding eliminates machining time and waste resulting in the lowest possible unit costs.

Injection molding is also the appropriate choice when machining presents difficult to overcome geometric challenges. Its durability, availability and processability make PEEK the material of choice when high strength and inertness especially at elevated temperature a fit in many industries.

New uses are being devised for the polymer all the time. The above is only scratching the surface for PEEK applications. PEEK is the most available and versatile high performance polymers on the market today. Its superior machinability and cleanliness make it ideal among all ketone based polymers for tightly toleranced complex machined parts or injection molded parts such gears, ferrules and life science and medical parts.

It is an excellent choice for highly load machined or molded parts. It is an excellent choice for highly load machined or molded parts including back up seals and electrical connector bodies.

The most common grades contain a combination of graphite, PTFE and carbon fiber with the most common ration being blend. This combination promotes low friction and higher conductivity enabling for higher PVs and lower wear rates. Why PEEK? It is useful at temperatures up to nearly degrees Fahrenheit long term and far higher short term, which is well beyond what most polymers are capable of.

This inherent characteristic can be compensated for through reinforcements and chemistry modifications. Some of the chemicals it can withstand include most acids the only exceptions are hydrofluoric and hydrobromicacetone, all alcohols, ammonia, benzene, chlorine, ethylene oxide, formaldehyde, gasoline and most fuels, glycerin, hydrogen peroxide, hydrogen sulfide, methane, MEK, methylene chloride, ozone, pentane, sodium carbonate, sodium hydroxide and Toluene.

This broad resistance is a primary reason why PEEK is so ubiquitous, as it can be adapted for nearly any application. Fatigue wear refers to material deformation resulting from repeated pressure and stress. PEEK that is alloyed with PTFE graphite and carbon fiber provides low wear rates at high pressure-velocity conditions in even abrasive environments.
