Problems solved by technology

Incorporating fibers into epoxy matrices has many advantages over unreinforced or virgin materials, but a significant disadvantage of fibers (natural or synthetic) is their weak bonding to the epoxy matrix, due to the There is an incompatibility, which r

Abstract

The invention discloses a glass fiber composite material. The glass fiber composite material is prepared from the following raw materials by weight: 40-60 parts of epoxy resin; 30-40 parts of unsaturated polyester resin; 60-70 parts of modified glass fiber; 5-10 parts of modified montmorillonite; 6-15 parts of graphite; 1-2 parts of chicken feather fiber; 0.3-0.5 part of an initiator; and 0.5-1 part of a curing agent; according to the invention, glass fiber is modified, and the hyperbranched polymer with hydroxyl grows on the glass fiber to improve the mechanical properties of the epoxy composite material; in addition, by modifying hydroxyl on the surface of the glass fiber, the crosslinking density of the epoxy matrix and the glass fiber is improved, and the segmented movement of the epoxy matrix is inhibited, so that the glass-transition temperature of the composite material is increased; in addition to improving the mechanical properties, the glass fiber can also serve as a chemical barrier, thereby reducing the water absorption of the composite material.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a glass fiber composite material and a preparation method thereof. Background technique [0002] As the world's concern for environmental protection grows, so does the interest in the utilization of recycled and / or renewable raw materials, with natural fibers being particularly prominent, the first patents for natural fiber composites dating back to the sixties; in Synthetic fibers replaced natural fibers in the 1960s and 1980s due to their better performance and economic advantages, and from the 1990s environmental concerns led to interest in these composite materials. Research on the use of natural fibres, synthetic fibres, reinforced polymer composites has seen considerable investment in R&D over the past few decades. [0003] Glass fiber is an inorganic fiber material, and it can be used to reinforce resin to make composite materials with excellent performance. ...
