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
As a new type of engineering plastic, DCP

Abstract

The invention discloses a preparation technique for a glass fiber composite material, and relates to the technical field of glass fiber composite material preparation. The preparation technique comprises four machining steps of glass fiber preparation, polymer fiber preparation, treatment technique for silane coupling agent and finished product. The glass fiber composite material prepared through the preparation technique has the advantages that the cost of the used materials is low, the service life is long, and automatic production is convenient. The prepared glass fiber composite material is acid-base resisting, good in rigidity, aging resisting and oxidation resisting. Compared with untreated glass fiber, the surface and structure of the treated glass fiber are both changed. The surface of the polymer fiber treated through a coupling agent is no longer to be smooth, active groups are increased, gullies and attachments adhered on the surface are formed in the overall appearance, consistency of the glass fiber is increased, and mechanical property of the glass fiber composite material is increased at the same time.

Description

technical field [0001] The invention relates to the technical field of glass fiber preparation, in particular to a glass fiber composite material preparation process. Background technique [0002] Glass fiber has excellent properties such as good insulation, low thermal conductivity, and strong sound absorption. In recent years, it has been widely used in aerospace, military chemical and other fields. 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 ...
