Further, the epoxy resin is E51 epoxy resin.
Melt spinning is to carry out melt spinning in twin-screw in the step (1)；Thermal finalization is that heat is carried out at 150-160 DEG C
Sizing.
The step (1) specifically: polyether sulfone and epoxy resin are subjected to mechanical blending, double spiral shells then are added in blend
Melt spinning is carried out in bar, institute's spinning is collected by up- coiler, resulting silk, by up- coiler in debatching at a slow speed to winding bucket
On, the baking oven thermal finalization that the fiber on bucket passes through 150-160 DEG C is wound, composite fiber web is obtained.
The surface density of polyether sulfone contained by composite fiber web is 5-30g/m in the step (1)2。
The number of plies of composite fiber web and carbon fibre material ratio is 9-19:10-20 in the step (2)；Resin is perfused are as follows: fill
E51 epoxy resin is infused, filling temperature is 60-80 DEG C, viscosity 0.1-0.2Pas.
Solidification in the step (2) are as follows: solidification temperature is 120-180 DEG C, curing time 2-4h；Used curing agent
For amine curing agent.
A kind of carbon fiber resin matrix composite of the method preparation of the invention, it is multiple for interlayer toughened carbon fibre resin
Condensation material.
Beneficial effect
(1) present invention prepares polyether sulfone/epoxy resin composite fiber using melt spinning method, and composite fiber web is placed on carbon
Between fiber cloth, laminate is made using VARI moulding process, epoxy resin is added in polyether sulfone by mechanical blending, institute
Solution rate of the obtained composite fiber web than polyether sulfone fiber net in epoxy resin gets a promotion, and due to its net of web
The problem of shape structure has a positive effect to the infiltration of resin, and effective solution other structures hinder between carbon cloth infiltration；
(2) present invention passes through the ratio of control polyether sulfone and epoxy resin, so that composite fiber web (temperature under filling temperature
Degree is 60 DEG C) it is not dissolved in epoxy resin, dissolution rapidly at curing temperatures.After solidification, polyether sulfone microballoon mutually divides from matrix
It separates out and, the developing direction of crackle when these polyether sulfone microballoons mutually can change resin matrix brittle fracture, and hinder crackle
Extension, establish a kind of new method of interlayer toughened；
(3) preparation process simple operations of the present invention are strong, are suitble to industrialized production；The composite materials property of preparation obtains
To being promoted more by a small margin, interlaminar fracture toughness raising is more significant, has a good application prospect；
(4) carbon fibre composite after toughening improves significant compared to non-toughening, interlaminar fracture toughness.
