Problems solved by technology

[0005] The above method can improve the mechanical properties of carbon fiber reinforced polyether ether ketone composites, but there are the following problems: the mechanical properties of composites are improved by processing parameters, and the processing parameters that need to be adjusted for different equipment and products are different. There is not necessarily any reference value between them, and the improvement of mechanical properties is limited; the technical route for chemical modification of PEEK is long and the investment in equipment is huge, this solution is not suitable for product manufacturers

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a carbon fiber reinforced polyether ether ketone composite material. Background technique [0002] Polyether ether ketone is a fully aromatic semi-crystalline thermoplastic engineering plastic first developed by the British ICI company in 1978. Its macromolecular chain contains rigid benzene rings, flexible ether bonds and carbonyl groups, and its structure is regular. It has excellent properties. Mechanical properties, chemical corrosion resistance, fatigue resistance and remarkable thermal stability, and flame retardancy. [0003] Adding fibrous materials such as carbon fiber and glass fiber is a common method for further strengthening and heat-resistant modification of polyether ether ketone, and expanding its application in aerospace, mechanics, electrical, bioengineering and other fields. Due to the large shrinkage rate, high melt viscosity and poor fluidity of ...
