Problems solved by technology

In order to make full use of these properties, it is necessary to crystallize the resin, but if the crystallinity is too high, there is a problem that the durability and impact resistance will be reduced, and it is required to further improve these physical properties when it is made into a fiber-reinforced material.

Embodiment 1、2 and comparative example 1、2

[0230] The raw material pellets of polyether ether ketone described in Table 1 were put into a Φ40mm single-screw extruder, melted while kneading, extruded from a pipe head (T die), and adhered to a casting roll. (The arithmetic mean roughness (Ra) was 0.03 μm, and the maximum height roughness (Rz) was 0.34 μm) and cooled to obtain a crystallized thin film with a thickness of 100 μm. The temperature of the extruder, the pipe, and the tube head (T die) was set to 380°C, the temperature of the casting roll was set to 210°C, and the lip gap of the die lips was appropriately adjusted to form a film. In addition, the resin temperature of the extruder exit was 400 degreeC. The obtained crystallized film having a thickness of 100 μm was evaluated for the crystal melting temperature, crystal melting heat, crystallization temperature, number of folds, puncture impact strength, and tensile elastic modulus by the methods described below.

[0231] In addition, a crystallized film with a ...

Abstract

Provided is a member for a composite material having excellent rigidity, durability, impact resistance, and productivity. A member for a composite material, which contains a resin component that contains a polyaryletherketone as a main component, has a molecular weight distribution of 4-8 and a mass average molecular weight of 88000 or more, and contains a resin and reinforcing fibers having a number average fiber length of 5 mm or more.

Description

technical field [0001] The present invention relates to a polyaryl ether ketone-based member for composite materials that can be used in composite materials for electrical / electronic equipment, automobiles, aircraft, and the like, and a composite material and a moving body using the member for composite materials. The present invention also relates to a method for producing a thin film for a composite material. Background technique [0002] In recent years, polyetheretherketone (PEEK), polyetheretherketone (PEEK), Polyetherimide sulfone (PEI), polyether sulfone (PES), polyether ketone (PEK), polyether ketone ketone (PEKK), polyether ketone ether ketone ketone (PEKEKK), etc. are represented by super engineering plastics. [0003] Among them, polyether ether ketone is used as a matrix material of fiber reinforcing materials because of its excellent heat resistance, mechanical properties, chemical resistance, and the like. It is necessary to crystallize the resin in order to ...
