Problems solved by technology

Since the composite material is made by mixing two or more materials together through an auxiliary method, there is often a phase interface between the materials due to different properties, which will eventually cause changes in the shear force between the interface layers. Composite materials perform poorly

Abstract

The invention provides a preparation process of a glass fiber composite material. The preparation process comprises the steps of (1) a glass fiber high-temperature treatment process, (2) an acid-alkali etching treatment process, (3) a silane coupling agent treatment process, and (4) preparation of a glass fiber/dicyclopentadiene (DCPD) composite material. According to the process, glass fibers are modified, the treated glass fibers are analyzed by adopting an infrared spectrogram and SEM, and a result shows that the surface structure of the treated glass fibers is changed compared with the untreated glass fibers. The surface of the glass fibers after being treated by the coupling agent is not smooth, active groups are increased, the overall appearance is provided with valleys and attachments adhered on the surface of the glass fibers, and the compatibility of the glass fibers to a matrix can be improved. When the glass fibers are broken in the matrix after being treated by the coupling agent, no obvious interface exists between the fibers and the matrix. The mechanical properties of the composite material can be improved.

Description

technical field [0001] The invention relates to a glass fiber preparation process, more specifically a glass fiber composite material preparation process. Background technique [0002] Among many polymer composite materials, fiber-reinforced composite materials have attracted widespread attention because of their excellent comprehensive properties, such as high impact resistance, high modulus, high mechanical properties, and high wear resistance. Glass fiber has the advantages of good corrosion resistance, heat resistance, good mechanical strength, and low raw material prices, and is widely used in composite materials for reinforcement purposes. Since the composite material is made by mixing two or more materials together through an auxiliary method, there is often a phase interface between the materials due to different properties, which will eventually cause changes in the shear force between the interface layers. Composite materials do not perform well. As a new type of...
