Description
Technical Field
The invention belongs to the technical field of glass fiber reinforced plastics, and particularly relates to a method for improving the wear resistance of epoxy glass fiber reinforced plastics.
Background
Fiberglass reinforced plastics are materials formed into composite structures by embedding or wrapping fiberglass reinforcing materials in cured thermosetting resins. At present, the glass fiber reinforced plastic materials produced and used in the market are mostly molded by adopting resin-soaked glass cloth materials. The method has good infiltration effect, and the prepared glass fiber has high content. But due to the limitations of the volume and shape of the glass cloth, it is not particularly suitable for use in products that are not easily uniformly compressed, such as pipe joints, tee fittings, elbow fittings, etc. In addition, the glass fiber reinforced plastic material prepared has poor impact resistance and the laminated surface is easily delaminated. The epoxy glass fiber reinforced plastic is a low-pressure molding material formed by compounding an epoxy resin matrix and a reinforcing material (fiber and fabric thereof) through an interface between the epoxy resin matrix and the reinforcing material. According to its use, it can be broadly divided into: structural composites, functional composites and general purpose composites.
The structural composite material focuses on the combination of mechanical properties, is mainly used for a bearing member and has certain service performances such as heat resistance, moisture resistance and the like; functional composites focus on the combination of functionality, but also require certain mechanical properties.
However, the abrasion resistance of the epoxy glass fiber reinforced plastic prepared by the existing method is relatively common, and the phenomenon of serious abrasion occurs when the epoxy glass fiber reinforced plastic is in friction contact operation for a long time, so that the performance of the material is greatly reduced, and the service life is shortened.
