British ACO Polymer Products Co., Ltd. introduced a corrosion-resistant epoxy resin in January 2004 and developed a matching glass bead filler material. The composite material can be used as a mechanical transmission component and is actually used. The effect is good.
The company uses epoxy resin, glass beads and glass fiber as the raw material, first mixes into the premix (EFC), and then uses the casting process to make a quarter turn machine composite starter, including the starter Shells, pistons, covers, bottom plates, cylinders, etc. After performance tests, the flexural strength was 111.3 N/mm2, the tensile strength was 69 N/mm2, the compressive strength was 187 N/mm2, and the thermal deformation temperature was 160°C. According to the company, this new EFC ​​material can replace commonly used aluminum materials.
The EFC composite material is molded by a casting process and has a higher dimensional accuracy than the injection process or the molding process. Even for a cast part with a high strength requirement, no mechanical finishing is required, and the thickness of the finished material is applicable. The range is very wide, and the thick and thin parts can be formed at one time. For example, some round holes in the part must be post-processed for aluminum, but no post-processing is required for EFC. In addition, since the EFC material has good corrosion resistance, the wear of the cylindrical wall is very small, and it is no longer necessary to add bearings or other accessories inside.
Since the EFC composite material has undergone post-cure treatment at a higher temperature, it has greatly improved its strength and thermal stability, and its long-term working temperature can reach above 140°C. With the same strength performance, EFC materials are lighter, only a quarter of steel, and two-thirds of aluminum.
