Abstract

The invention discloses a preparation method of a fiber reinforced damping composite. The composite is prepared from epoxy resin, polymer polyurethane, styrene-butadiene-styrene copolymer, reinforcing fiber, mica powder, talcum powder, nano calcium carbonate, coupling agent, curing agent and foaming agent through melting, pressing or injection molding in four preparation steps, wherein reinforcing fiber is selected from glass fiber, carbon fiber, boron fiber, crystal whiskers or hard particles, and auxiliaries are mica powder and talcum powder with granularity of 80-140 mesh. By adding appropriate amounts of nano calcium carbonate and elastomers to a traditional base material, the stability, toughness and bending strength of the composite are greatly improved, and the composite has the advantages of being easy to machine and form, capable of absorbing shock and reducing noise and the like and can be used for machine parts or cushion blocks or sealing plates.
