Embodiment 1

[0026] A carbon fiber epoxy resin-based composite material ATR series chassis, the composite material ATR series chassis is prepared from carbon fiber epoxy resin-based composite material prepreg through laying, heating, pressurizing, and curing molding. The specific steps as follows:

[0027] The first step is material preparation, carbon fiber epoxy resin matrix composite material prepreg cutting;

[0028] Carbon fiber epoxy resin-based composite material prepreg is an intermediate material that is dipped into a resin matrix by directional arrayed fiber bundles or fabrics, and is stored for use after certain treatments. The purpose of cutting prepreg is to control the composite structure shape, thickness and meet the resin / fiber distribution specified by the design. The designability of the composite material is achieved by adjusting the thickness of the prepreg, the orientation of the fibers and its lay-up sequence, and then closed curing to make a high-quality finished pr...

Abstract

The invention provides an ATR series chassis made of carbon fiber epoxy resin matrix composite material. The composite material ATR series case is prepared by laying up carbon fiber epoxy resin based composite material prepreg, heating, pressurizing and curing. The present invention uses the carbon fiber reinforced material of the new composite material and the resin-based composite material to prepare the ATR series chassis products, which are manufactured by one-time membrane pressing. The product has high processing precision and good consistency, no need for subsequent mechanical processing, high raw material utilization rate, no waste, and is suitable for mass production. Carbon fiber epoxy resin matrix composite material has high strength, flame retardancy and corrosion resistance. The product does not require surface protection treatment, and is suitable for harsh environments such as acid, alkali, and salt spray. Due to the low specific gravity of carbon fiber epoxy resin-based composite materials (aluminum alloy 1.4-1.6g / cm 3 ), the unit weight of the product parts is lighter.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to an ATR series chassis made of carbon fiber epoxy resin-based composite materials. Background technique [0002] Carbon fiber composite materials rose in the 1960s, with the industrial production of epoxy resin in the 1950s. Carbon fiber composite materials have also entered into industrial practical applications. Composite materials have shown strong vitality with their excellent material properties. At the end of the last century and the beginning of this century, my country entered a period of rapid development of modernization, and composite materials were widely used in aviation, aerospace, navigation, petrochemical and other fields. And it has become the four major structural materials of aviation and aerospace together with aluminum alloy, titanium alloy and alloy steel. [0003] At present, the manufacturing method of traditional ATR chassis adop...
