The molding process of G11 epoxy glass fiber tube is to impregnate the glass fiber filament with resin and then solidify it in a high-speed polymerization device integrated with photoelectric and heat, and then pultrude it by traction. Due to the different types of resins used, it is called polyester fiberglass, epoxy fiberglass, and phenolic fiberglass. It has the characteristics of light and har...

The raw material properties of epoxy resin rods in terms of high temperature performance, low temperature performance, tensile performance and water permeability are tested. The specific test methods and test results are as follows. 1. High temperature test Since the asphalt concrete of the pavement layer has the characteristics of high mixing temperature and high construction temperature, and the...
