One-Stop Service For Lightweight Fiberglass Material

Thermoplastic skins or laminate sheets are composite sheets composed of Continuous Fiber Reinforced Thermoplastic (CFRT) unidirectional prepreg tapes, arranged in one or more combinations of fiber orientations, such as 0°, 45°, -45°, 90°, etc.

These sheets are manufactured through a process involving both hot and cold pressing.

Additionally, they can be integrated with high-performance core materials, including honeycomb sandwich panels, PET foams, polyurethane panels, among others, or can be combined with non-woven materials to create innovative sandwich composite panels

Advancements in Medical Engineering: Harnessing the Potential of Carbon Fiber-Reinforced PEEK Composites

Polyetheretherketone (PEEK), with its complete English name, is an exceptional special engineering plastic known for its high heat resistance (exceeding 260℃), outstanding mechanical properties, and chemical stability.

It can replace traditional materials such as metals and ceramics in many specialized fields.

Moreover, PEEK exhibits good thermal stability and melt flowability above its melting point, thus possessing typical processing properties of thermoplastic materials.

PEEK resin is non-toxic, lightweight, and corrosion-resistant, making it one of the materials closest to the human skeletal system.

It exhibits excellent compatibility with the body and is often used to manufacture human skeletal replacements instead of metal.

Carbon fiber reinforced PEEK composites materials address the weaknesses of toughness and impact resistance.

These composites demonstrate high mechanical strength and hydrolytic stability under conditions such as hot water, steam, solvents, and chemical reagents, making them suitable for various medical devices requiring high-temperature steam sterilization.

Applications of carbon fiber reinforced PEEK composites in the medical field can be divided into below categories


There is high demand for implant materials, including good biocompatibility and lifelong durability.

While metals have traditionally been the preferred choice for implants, the introduction of PEEK has disrupted this pattern.

PEEK implants must meet the requirements of ASTM F2026 and can be used in various clinical applications involving implants or contact with blood, bones, and tissues for more than 30 days.

These applications include spinal fusion devices, trauma bone fracture fixation, orthopedics, craniofacial surgery, oral restoration, as well as valve stents, gastrointestinal stents, implantable fluid pumps, sublingual nerve stimulation systems, among others.


The excellent chemical stability, strength, rigidity, and toughness of PEEK make it suitable for medical device applications such as drug delivery, dental bases, catheters, blood management, and surgical instruments.

Common processing techniques for medical-grade PEEK include continuous carbon fiber 3D printing and injection molding.

3D printing allows to produce complex spatial structures, while recycling of unfused powder can improve material utilization and control production costs.

To meet the complex physiological environment of the human body, materials for implantable medical devices must satisfy four requirements:

  • Excellent tissue and physical compatibility.
  • Excellent chemical stability, ensuring material properties remain unchanged in biological environments and do not induce rejection reactions. Materials must also maintain stability under various sterilization conditions.
  • Excellent mechanical properties to withstand biological mechanical forces and match the mechanical properties of biological tissues.
  • Good processability to meet different processing conditions and produce biomaterials of various structures, shapes, and sizes to meet therapeutic needs.

Scientific studies have shown that implantable carbon fiber reinforced PEEK composites are not only non-cytotoxic but also promote protein synthesis and bone formation in bone cells.

When used as artificial joint prostheses, they exhibit excellent ability to promote bone cell proliferation and adhesion.

PEEK bonds

The interface bonding strength between carbon fiber reinforced PEEK composites and bone is superior to other artificial joint materials, resulting in clinical outcomes superior to those of metal materials and mitigating complications such as loosening of joint prostheses due to mechanical and biological incompatibility.

The main advantages of carbon fiber-reinforced PEEK composites in medical applications include:

  1. Lightweight with high strength.
  2. Excellent wear resistance.
  3. Biocompatibility.
  4. Corrosion resistance.
  5. Good X-ray transparency, facilitating accurate diagnosis.

Carbon fiber-reinforced PEEK materials exhibit superior X-ray penetration capabilities compared to traditional medical devices made of stainless steel or hard aluminum alloys.

PEEK Application

This transparency aids doctors in making precise diagnoses during bone fracture rehabilitation treatments.

Carbon fiber reinforced PEEK composites, originally used in aerospace applications (Automated Tape laying and PEEK screws), have extended into the medical industry.
