Polydicyclopentadiene composite material reinforced by mixing polyester fibers and glass fibers and preparation method of polydicyclopentadiene composite material

The invention discloses a polyester fiber and glass fiber mixed reinforced polydicyclopentadiene composite material and a preparation method thereof. The polyester fiber and glass fiber mixed reinforced polydicyclopentadiene composite material is used for improving the impact strength, tensile strength and bending strength of a polydicyclopentadiene material. The technical scheme is as follows: raw materials comprise the following components in percentage by weight: 2.8%-7.8% of polyester fibers, 36.9%-69.3% of glass fibers, 28.3%-55.3% of dicyclopentadiene and 0.01%-0.15% of a catalyst. The preparation method of the composite material comprises the following steps: (1) arranging polyester fiber cloth in a forming container; (2) paving glass fiber cloth on the polyester fibers in the step (1) according to a certain sequence; and (3) uniformly mixing a dicyclopentadiene monomer and a catalyst, injecting the mixture into the molding container in the step (2), and carrying out polymerization curing molding at a
