Resin matrix of carbon fiber reinforced composite material, carbon fiber reinforced composite material and preparation method thereof, table tennis racket bottom plate

Abstract

The invention relates to a carbon fiber-reinforced composite material resin matrix, a carbon fiber-reinforced composite material and a preparation method thereof, and a table tennis bat base plate, and belongs to the technical field of carbon fiber-reinforced composite materials. The carbon fiber-reinforced composite resin matrix is prepared from 95 to 105 parts by weight of epoxy resin, 70 to 80parts by weight of endomethine tetrahydrophthalic anhydride, and 4 to 6 parts by weight of dimethylaniline. The carbon fiber-reinforced composite resin matrix utilizes simple raw materials, has high specific strength, specific modulus, dimensional stability, excellent corrosion resistance, abrasion resistance and electrical insulation and has a good application prospect in preparation of a table tennis bat material.

Description

technical field [0001] The invention relates to a carbon fiber-reinforced composite material resin matrix, a carbon fiber-reinforced composite material and a preparation method thereof, and a bottom plate of a table tennis racket, belonging to the technical field of carbon fiber-reinforced composite materials. Background technique [0002] Most of the existing table tennis bottoms on the market are solid wood bottoms. Due to the difference in the internal structure of the wood, the strength and modulus of the solid wood bottoms will be anisotropic and unstable, while the carbon fiber material has low density, light weight, and high temperature resistance. And corrosion, soft on the outside and rigid on the inside, high specific strength and specific modulus, and the same strength and modulus in all directions, so carbon fiber composite materials can be used instead of solid wood to make table tennis bottom plates. [0003] The Chinese invention patent with application public...

Problems solved by technology

The blended resin disclosed in this patent contains a variety of resins and needs to be cross-linked. The preparation is relatively cumbersome, and the mechanical properties of the final composite material still need to be further improved.

[0004] The Chinese invention patent with the application publication number of CN 106633624A discloses a new type of table tennis racket bottom plate made of basalt composite material, which is mainly processed by the process of immersing multi-layer basalt fiber cloth in resin mixture and integral molding. It is prepared from the following raw materials in parts by weight: double horse modified phenolic resin, polyaryl acetylene resin, phenylacryltriazole, dialkyl diphenylamine, dodecyl trimethyl ammonium bromide, sodium fatty alcohol sulfate , Potassium dichloroisocyanurate, fatty alcohol polyoxyethylene ether, zinc naphthenate, terephthaloyl chloride, reactant of quaternized ammonium chloride, polyamide wax micropowder, the composition of the resin mixture is complex, still Need to be further improved, and its mechanical properties also need to be further improved
