Composite has that thermal coefficient of expansion is small, and specific heat capacity is high, can store substantial amounts of heat energy, the features such as low thermal conductivity.By external force
In the case of, load is effectively delivered on glass by interface, improves the bending strength of composite.Glass also may be used simultaneously
To strengthen the performances such as the heat shock resistance of composite and thermal friction.
But fiber surface is smooth, inertia, the poor adhesion with matrix, at the same it is scattered bad in matrix resin.Thus
Simple fiber improvement PEEK composite material interface bonding strengths are low, and material property is unstable, when material is acted on by external force, fiber
Easily extracted from matrix, load can not be transmitted effectively by interface.The combination property of composite has been had a strong impact on, has been limited
The application field of material.
Meanwhile in molten state with the extension of soaking time itself can occur for the PEEK for being not added with any antioxidant
The degraded crosslinking of strand, increases the viscosity of polymer, partial properties reduce, and have had a strong impact on PEEK processing characteristics and production
Product stability.
