PEEK, a typical high-performance thermoplastic resin, boasts outstanding properties across various applications. When combined with continuous carbon fiber, the combined properties of the two materials effectively combine, resulting in even better overall performance. Due to their exceptional performance, continuous carbon fiber/PEEK thermoplastic composites have been widely used in aerospace, medical, automotive, and other fields, and are currently a focus of research at major universities, research institutions, and businesses.

Advantages of continuous carbon fiber CF/PEEK composite materials:
1. Good elongation at break and fracture toughness
As a representative of high-performance thermoplastic polymers, PEEK has a fracture toughness of up to 2.0 KJ/m, which is 20 times that of epoxy resin.
2. Excellent anti-delamination and fatigue resistance
PEEK has good impact resistance, making it one of the best heat-resistant resins. It also has high rigidity, good dimensional stability, and a low linear expansion coefficient, resulting in excellent long-term creep and fatigue resistance.
3. Excellent resistance to chemical corrosion
PEEK has excellent chemical corrosion resistance and is highly resistant to acids, alkalis, and almost all organic solvents. It is only corroded by halogens and strong acids at high temperatures and is only soluble in concentrated sulfuric acid at room temperature.
4. Excellent moisture and heat resistance
PEEK has low moisture absorption rate, good resistance to moisture and heat, and can maintain good mechanical properties under high temperature and high humidity. In addition, it has outstanding hydrolysis resistance, low moisture absorption and permeability, and is resistant to steam, water and seawater.
5. Excellent sliding wear and fretting wear
PEEK can maintain high wear resistance and low friction coefficient at 260 ℃.
6. Biocompatibility
Studies have shown that short carbon fiber reinforced PEEK as a prosthetic material implanted into animals has low cytotoxicity, meets the cytotoxicity indicators of medical implant materials, and has good blood compatibility and tissue compatibility.
7. X-ray transparent
PEEK has good transmission properties and does not produce artifacts like metal implants under X-ray and CT examinations, making it easier for patients to undergo medical examinations.
