Description

Next-Generation Structural Composites for Extreme Operating Environments

Traditional thermoset (epoxy) prepregs pose significant operational challenges: strict frozen storage limits, slow autoclave curing cycles, and susceptibility to micro-cracking under impact.

Our Continuous Carbon Fiber Reinforced PEEK (CF/PEEK) Prepreg Tape represents the pinnacle of thermoplastic composites. By combining high-modulus carbon fibers (T700 / T800 grade) with an engineering PEEK polymer matrix, it provides metal-like structural strength, extreme fatigue resistance, and recyclability—engineered for high-rate aerospace, defense, and demanding industrial components.

Material overview

Understanding PEEK (Polyether Ether Ketone)

PEEK is a semi-crystalline high-performance thermoplastic. Its combination of aromatic structure and ketone/ether linkages supports heat resistance, chemical durability and mechanical strength, while its crystallinity and processing history influence stiffness, wear, shrinkage and final dimensions.

Why engineers use it

  • Strong balance of heat, chemical and mechanical performance.
  • Can be molded, extruded, machined or printed in suitable grades and equipment.
  • Good fatigue and wear potential for demanding moving or loaded parts.
  • Available in unfilled, glass-fiber, carbon-fiber and wear-modified grades.
  • Suitable for precision components where long-term reliability justifies a specialty polymer.

Limits to consider

  • High processing temperature requires capable equipment and controlled drying.
  • Crystallinity, cooling and annealing can affect dimensions and performance.
  • Reinforcement improves some properties but may reduce ductility or change machining behavior.
  • Not every chemical, wear or medical application is covered by a standard industrial grade.
  • PEEK can be unnecessary over-specification where PPS, PEI or another polymer meets the duty.

Grades and product forms

Unfilled PEEK provides the broad base-property balance. Glass-fiber grades generally target stiffness and dimensional control; carbon-fiber grades may add stiffness, strength and conductivity; bearing grades use fillers such as carbon, graphite or PTFE to tune friction and wear. Film, filament, powder, pellets and stock shapes each require different processing and purchasing information.

Performance points to review

Evaluation areaWhy it mattersInformation to provide
Temperature behaviorUseful performance under elevated or changing temperatureContinuous and peak temperature, cycle length and time at load
Mechanical responseStrength and stiffness must match the real part geometryLoad direction, stress level, impact and fatigue expectations
Environmental resistanceFluids, cleaning agents and atmosphere can change service lifeChemical name, concentration, temperature and exposure time
Dimensional controlTight-tolerance parts depend on both material and processingFinished dimensions, tolerances and assembly conditions
Electrical or insulation needsElectrical requirements may influence grade and thicknessVoltage, dielectric, conductivity or insulation target

These are engineering discussion points, not guaranteed property values. Final acceptance criteria should be agreed for the selected grade, process and order.

Typical application directions

These examples show where the material may be evaluated. They do not replace a suitability review for the finished component.

Process equipmentComponents exposed to heat, chemicals or repeated production cycles.
Electrical systemsInsulators, supports and precision parts where stable behavior matters.
MachineryWear parts, guides and structural components selected around real loads.
Laboratory equipmentParts requiring clean handling, dimensional stability or fluid resistance.
Custom componentsMachined or molded parts developed from a drawing or existing sample.
Prototype developmentTrial quantities used to confirm processing and end-use performance.

Preparing a high-temperature printing project

Provide filament diameter, printer model, nozzle and chamber capability, drying method, build geometry, support strategy and annealing plan. A high-performance filament cannot compensate for a printer that lacks the necessary thermal control.

Where the application is critical, define what a successful trial looks like before material is ordered: dimensions after processing, visual condition, mechanical response, assembly fit or another measurable result.

When another material may be better

PPS, PEI, PSU/PPSU or a conventional engineering plastic may be more economical when temperature, chemical and mechanical requirements are moderate. PEEK is justified when several demanding requirements occur together or when service life and reliability outweigh raw-material cost.

We recommend sharing the current material and the reason it is being reconsidered. Cost, processability, supply form and inspection burden belong in the decision alongside technical performance.

Frequently asked questions

Can I request a sample or trial quantity?

Trial quantities can be discussed according to product form and availability. Tell us what you need to prove during the trial, the intended process and the expected production quantity if the test succeeds.

Do you provide a data sheet or material documentation?

Available documentation depends on the selected material and supply route. List the documents required by engineering, purchasing or quality when you inquire so they can be checked before quotation.

Can the grade be selected from a product name alone?

No. Similar product names can cover different grades, colors, fillers and processes. Selection should be based on the finished application, environment and required property balance.

Can you supply custom dimensions or finished parts?

Custom sizes, blanks or finished parts can be reviewed where appropriate. A drawing with tolerances, quantity and material requirement is the best basis for quotation.

How should we evaluate an alternative to our current material?

Share the current grade, the part’s service conditions and the reason for changing it. A useful comparison looks at failure mode, processing, life, inspection and total project cost—not only a single property value.

What determines lead time?

Lead time depends on product form, grade, size, quantity, documentation, machining and current availability. Confirm the required delivery date and destination with the RFQ rather than assuming a standard schedule.
