Problems solved by technology

[0002] Geosynthetics are widely used in engineering reinforcement because of their low cost, simple construction and good reinforcement effect. However, most of the traditional geosynthetics are non-renewable resources, not easy to degrade, and their production process is more polluted, which is not conducive to environmental protection.
The coconut shell fiber is natural pollution-free, green, renewable, strong toughness, high strength, and wide source. It is an ideal natural reinforcement material. It will degrade in one or two years in the state, and it is not suitable for engineering projects with a long operating time, and it needs to be treated with anti-corrosion

Abstract

The invention relates to a preparation method of a natural coconut fiber reinforced epoxy resin composite fabric. The preparation method of the natural coconut shell fiber reinforced epoxy resin composite fabric comprises the steps of trimming prepared coconut shell fibers into fiber segments with the length of 0.5-5 cm; mixing and stirring the fiber segments and molten epoxy resin for 10-20 min in a spherical stirrer according to the mass ratio of 5%-20% to form uniformly-dispersed composite resin melt; coating a first layer of release agent on the inner surface of the mold, standing, coatinga second layer of release agent after the release agent is solidified, and slowly injecting the composite resin melt into the mold after the two layers of release agents are completely solidified; scraping and roughly machining the surface of the composite fabric through a scraper, and conducting curing forming in the room temperature state; and demolding and trimming the cured rough machining composite fabric to form the reinforced composite fabric. The preparation method of the natural coconut fiber reinforced epoxy resin composite fabric has the advantage of high durability.

Description

technical field [0001] The application relates to a preparation method, in particular to a preparation method of a natural coconut fiber reinforced epoxy resin composite fabric. Background technique [0002] Geosynthetics are widely used in engineering reinforcement due to low cost, simple construction and good reinforcement effect. However, traditional geosynthetics are mostly non-renewable resources, not easy to degrade, and their production process is more polluting, which is not conducive to environmental protection. The coconut shell fiber is natural pollution-free, green, renewable, strong toughness, high strength, and wide source. It is an ideal natural reinforcement material. It will degrade in one or two years in the state, and it is not suitable for engineering projects with a long operating time, and it needs to be treated with anti-corrosion. Contents of the invention [0003] Based on this, the purpose of this application is to provide a preparation method fo...
