Polymer Composite Classification
- Aug 17, 2018 -

Polymer composite materials are divided into two categories: polymer structural composite materials and polymer functional composite materials. The former is the main one. The polymeric structural composite comprises two components: a reinforcing agent. It is a fabric with high strength, high modulus and temperature resistance, such as glass fiber, silicon nitride whisker, boron fiber and the above fiber. 2 matrix material. Mainly adhesives, such as non-saturated polyester resin, epoxy resin, phenolic resin, polyimide and other thermosetting resins and thermoplastic resins such as styrene and polypropylene. The specific strength and ratio of this composite. The modulus is higher than that of metal, and it is an indispensable material for national defense and cutting-edge technology. The polymer functional composite material is also composed of a resin matrix material and a material having a special function, such as certain materials of conductivity, semiconductivity, magnetism, luminescence, piezoelectricity, etc., and is compounded with a binder to make it Has new features. Magnetic seals such as refrigerators are such composite materials.
