Problems solved by technology

[0003] However, when the above-mentioned technical solutions are actually used, there are still many shortcomings. For example, biodegradable resin-based composite materials have poor high-temperature resistance during use, and some need to be used under high-temperature conditions. Therefore, biodegradable resin-based composite materials Materials require high temperature resistance, flexural strength, flexural modulus

Abstract

The invention discloses a preparation process of a biodegradable resin-based composite material, and particularly relates to the field of resin-based composite materials. The preparation process specifically comprises the following steps: step 1, adding 100-200 parts of epoxy resin, 150-200 parts of phenolic resin and 100-120 parts of organic silicon resin into a stirring smelting furnace, heatingthe stirring smelting furnace to 300-400 DEG C, and stirring at the speed of 60-80 rpm, and stopping stirring after the substances are fully and uniformly mixed. The cyanate ester resin and the bismaleimide are plasticized and molded so that the high temperature resistance can be greatly improved, the bending strength and the bending modulus of the matrix are also improved, the use effect is moredurable and not easy to wear, and the service life of the biodegradable resin-based composite material is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of resin-based composite materials, and more specifically, the invention relates to a preparation process of biodegradable resin-based composite materials. Background technique [0002] At present, resin-based composite materials are fiber-reinforced materials based on organic polymers. Fiber reinforcements such as glass fiber, carbon fiber, basalt fiber or aramid fiber are usually used. Resin-based composite materials can be used in the aviation field. High-performance glass fiber Instead of ordinary glass fiber, after the 1970s, aromatic polyamide fiber was used instead of resin-based composite materials, and the strength was greatly improved, while the weight was reduced. Biodegradable resin-based composite materials performed better in the fields of aircraft, missiles, and satellites. At the same time, biodegradable resin-based composite materials can not only protect the environment, but also have a par...
