Question:

Are epoxy resins and glass fibers the same kind of thing?

Are epoxy resins and glass fibers the same kind of thing?

Answer:

Epoxy resin board is epoxy resin, yarn, film stripping agent, curing agent pultrusion. After curing epoxy resin system is a kind of excellent insulating materials with high dielectric properties and high surface leakage current, arc resistance, their phenolic resin and unsaturated polyester resin, compared to show a very low shrinkage sex during the curing process (less than 2%). Epoxy is about twice as expensive as glass fiber.
Glass fiber is a kind of inorganic non-metallic material with excellent performance. It has many advantages, such as good insulation, good heat resistance, good corrosion resistance and high mechanical strength, but its disadvantages are brittleness and poor wear resistance. It is a glass ball or waste glass as raw materials by high temperature melting, wire drawing, winding and weaving process for production, the filament diameter of several microns to twenty micron, the equivalent of a hair 1/20-1/5, each bundle of fibers by hundreds or even thousands of root root filaments.
Epoxy resins refer to organic compounds containing two or more epoxy groups in the molecule. Except for some of them, the relative molecular weight of them is not high enough. (two). The molecular structure of epoxy resin is characterized by the presence of active epoxy groups in the molecular chain. The epoxy group can be located at the end of the molecular chain, intermediate or ring like structure. Because the molecular structure contains active epoxy groups, they can react with various types of curing agents to form insoluble polymers with three directions network structure. Any polymer compound with epoxy groups in its molecular structure is collectively referred to as an epoxy resin.
