Abstract

The invention discloses unsaturated polyester and a fiber reinforced composite material thereof based on an environment-friendly reactive solvent. A styrene-free unsaturated polyester resin matrix is synthesized by taking propylene glycol, isophthalic acid and fumaric acid as raw materials under certain conditions, and then the composite material is prepared by carrying out hot-press molding on the styrene-free unsaturated polyester resin matrix based on N-vinylpyrrolidone as a reactive solvent and raw bamboo fiber as a reinforcement body. Since the unsaturated polyester used in the composite material prepared by the method is free of the reactive solvent having carcinogenicity styrene, the unsaturated polyester has the characteristics of environment friendliness and low cost, and the prepared composite material has the advantages of very high tensile strength, flexural strength, flexural modulus and impact strength.

Description

technical field [0001] The invention belongs to the technical field of fiber-reinforced resin composite materials, and in particular relates to an unsaturated polyester based on an environment-friendly reactive solvent and fiber-reinforced composite materials thereof. Background technique [0002] Unsaturated polyester (UPE) is the most used resin variety in glass fiber reinforced resin composite materials. UPE resin has good mechanical properties and manufacturability, but a large amount of volatile styrene is used as diluent and crosslinking agent in the preparation process, and the resulting air pollution has attracted great attention. In 2011, the U.S. Department of Health and Human Services officially listed styrene and respirable fiberglass as carcinogens. Therefore, for the fiber-reinforced resin-based composite material industry, it is necessary to seek new reinforcements to minimize the use of glass fibers, and at the same time take measures to reduce the amount of...
