Abstract

The invention discloses a natural fiber resin composite and a preparation method thereof. The natural fiber resin composite is prepared from the following components in part by weight: 10-50 parts of waterborne resin, 10-50 parts of non-aqueous epoxy resin, 50-200 parts of natural fiber, 3-15 parts of water soluble hardening agent, 6-15 parts of phase transfer catalyst, 50-150 parts of filler and 100-200 parts of water. The natural fiber resin composite has the characteristics of high strength and low cost.

Description

technical field [0001] The invention relates to a natural fiber resin composite material and a preparation method thereof. Background technique [0002] Composite material is defined as a combination of two or more materials to form a new material, which has the advantages of the original two materials. At present, the fibers used in composite materials mainly include glass fiber and carbon fiber. Although carbon fiber has excellent performance, it is The production process is complicated, so the cost is very high; while the performance of glass fiber is worse than that of carbon fiber, and its quality is heavier than carbon fiber. Although the production process is simpler than carbon fiber, it is still very complicated. [0003] Compared with the above two fibers, natural fibers are easy to obtain and cheap in price, but natural fibers are not water resistant and are easily decomposed by bacteria, thus limiting their use. In order to improve the above-mentioned characteri...
