Problems solved by technology

However, since the large tow fibers contain 48,000 fibers or more per bundle, the fiber bundle size is thicker, and the impregnation and wrapping ability of the resin is poorer. It is difficult to prepare fiber composite materials with excellent performance by using a suitable process High-performance composite drive shaft

Abstract

The invention discloses medium-and-low-temperature epoxy resin and a preparation method and application thereof in a big-and-small-tow carbon fiber epoxy composite transmission shaft, belongs to the technical field of automobile transmission shaft lightweight manufacturing and solves the problem that resin is low in impregnation ability, high in curing temperature, long in time and unsupportive ofvolume production in the process of manufacturing automobile transmission shafts in the prior art. The medium-and-low-temperature epoxy resin is composed of a component A and a component B, the component A comprises, by weight, 5-10 parts of nano modified bisphenol A epoxy resin, 60-75 parts of phenolic epoxy resin and 10-15 parts of glycidyl amine epoxy resin, and the component B comprises, by weight, 15-20 parts of fatty amine at least containing one tertiary amine, 15-20 parts of aromatic amine at least containing one tertiary amine, 20-25 parts of alicyclic amine with two primary amines and 10-15 parts of oligopolyphosphate. Viscosity of the resin at 55 DEG C is 100-2000cp, curing molding temperature is 70-90 DEG C, and curing time is 0.5-1.5h.

Description

technical field [0001] The invention belongs to the technical field of lightweight manufacturing of automobile transmission shafts, and in particular relates to a medium-low temperature curing epoxy resin, a preparation method thereof, and an application in large and small tow carbon fiber epoxy composite transmission shafts. Background technique [0002] As an important power transmission component in the vehicle transmission system, the transmission shaft is used to effectively transmit the power generated during the operation of the engine to the wheels together with the gearbox and drive axle to make the vehicle generate driving force. According to the research results, the impulsive system will consume 20% of the engine energy due to its own weight during its own operation, and the transmission shaft made of metal will cause a large loss of engine energy utilization efficiency due to the large body density of the metal itself. The transmission shaft of the automobile is...
