Fiber reinforced composite material and preparation method thereof

Abstract

The invention provides a fiber reinforced composite material and a preparation method of the fiber reinforced composite material. The method comprises the following steps: preparing a mandrel; an inner prefabricated pipe is arranged on the core shaft in a sleeving mode; the two ends of the inner prefabricated pipe are connected with positioning plates correspondingly, and angle bisectors are arranged on the opposite faces of the two positioning plates; guide plates are installed on the outer surface of the inner prefabricated pipe one by one with the bisectrixes on the positioning plate as alignment lines; the positioning plates at the two ends of the inner prefabricated pipe are taken down, and fiber bundles are placed in the spiral grooves; an outer prefabricated pipe is arranged on the periphery of the guide plate in a sleeving mode, and a plug is additionally arranged at one end of the outer prefabricated pipe so as to seal the end; filling materials are poured into the spiral groove from the other end of the outer prefabricated pipe; after pouring is completed, curing is conducted at the preset temperature; and after curing is completed, the core shaft is taken out of the inner prefabricated pipe. According to the composite material electric pole core mold, the production process can be simplified, and the production difficulty can be reduced.

Description

technical field [0001] Embodiments of the invention relate generally to the field of composite materials, and more particularly, to fiber-reinforced composite materials and methods of making fiber-reinforced composite materials. Background technique [0002] Existing composite materials such as composite poles are usually manufactured by winding layers of different materials on a mandrel. For example, the publication number is CN101368453A, and the title of invention is the electric pole of composite material described in "Production method of high-strength composite electric pole". It needs to use a winding device to perform multiple and complicated layer-by-layer winding operations on the outer periphery of the mandrel, which has a long production cycle, high production difficulty and high cost. In practical applications, some composite materials such as composite poles only need to withstand a certain angle of torque, and the fiber bundle can be directly used to reinforc...

Problems solved by technology

It needs to use a winding device to perform multiple and complicated layer-by-layer winding operations on the outer periphery of the mandrel, which has a long production cycle, is difficult to produce, and costs high

In practical applications, some composite materials such as composite poles only need to withstand a certain angle of torque, and the fiber bundle can be directly used to reinforce the resin matrix at the core to achieve the fiber reinforcement effect, without using a special winding device for complex Winding layer by layer, but there is no simple mandrel in the prior art to make this composite material
