Materials Technical Data Sheet
Product description
CF/PEEK UD prepreg tapes is a kind of high-performance thermoplastic composite material made by carbon fiber and PEEK, which could be used in aerospace, military, medical, automotive and many other high temperature applications for a long time due to the chemical stability and durability. The polymer is semi-crystalline with a glass transition temperature of 143℃. The composites possess excellent environmental resistance, toughness, and fire-resistant properties. The material could be formed by autoclave consolidation, wrapping (in-situ curing), automatic placement (in-situ curing) and other processes.
Key Features
Excellent mechanical performance.
Low water absorption, high hydrothermal properties.
Excellent chemical and solvent resistance.
Outstanding flame retardant performance.
Stable performance under unlimited storage at room temperature.
General requirements
● Prepreg resin was uniformly distributed.
● Prepreg fiber were parallel and continuous, no obvious wrinkle, cross.
● No foreign objectives on the surface of prepreg.
Allowed defects
The length of the fiber gap should not exceed 250 mm, and the width should not exceed 1.2 mm.
Defect identification
The prepreg contains a defect mark indicating the type of defect. The defective part is not included in the delivery quantity.
