Abstract

The invention provides a preparation method of a fiber composite material and special equipment for the preparation method and belongs to the technical field of composite material preparation. The equipment comprises a rack, a fiber processing module, a photocuring forming module and a computer containing control software. The method comprises the steps that firstly, a three-dimensional entity model of a fabricated piece is sliced and layered with layering software; then, the fiber processing module is called to perform distribution processing on the specific area of fiber according to a set fiber spreading path program; next, a movement mechanism is called, and loading of the prefabricated fiber on the surface of the fabricated piece is achieved; and finally, in combination with a photocuring forming system, composite single-layer printing of a photocuring material and a fiber material is achieved, layer-by-layer accumulation is performed, a fiber-reinforced resin fabricated piece or a fiber composite ceramic blank is obtained, and a fiber-reinforced ceramic fabricated piece can be obtained after the fiber composite ceramic blank is subjected to postprocessing, degreasing and sintering. The fiber content and distribution area are controllable, and a fiber-reinforced body in a resin/ceramic base body can be designed flexibly.

Description

technical field [0001] The invention relates to a preparation method of a fiber-reinforced composite material and special equipment thereof, belonging to the technical field of composite material preparation. Background technique [0002] Adding fibers to matrix materials has always been a composite method to improve the performance of materials. From polymer materials to ceramic materials, adding fiber components can improve the performance of materials. [0003] The traditional fiber composite method is to pre-add fibers to the resin / ceramic slurry, and then use molds to form them. It is impossible to prepare parts with complex shapes, and the composition and gradient of fiber addition cannot be freely controlled, and cannot be adjusted according to performance requirements. Free design. [0004] Light-curing rapid prototyping technology is one of the methods with the highest molding precision in additive manufacturing technology. Light-curing rapid prototyping technolog...
