Abstract

The invention discloses glass fiber reinforced prepreg prepared from toughened environment-friendly phenolic resin and relates to the technical field of processing and manufacturing of materials for synthetic resin. The glass fiber reinforced prepreg is characterized by comprising environment-friendly phenolic resin, alkali-free glass fiber cloth, a coupling agent KH-560, an internal releasing agent, pigments, silica, industrial alcohol, graphite and silicone lime. The glass fiber reinforced prepreg is reasonable in method, clear in proportion, high in electric strength, high in tensile strength and high in bending strength.

Description

Technical field: [0001] The invention relates to the technical field of material processing and production of synthetic resins, in particular to a glass fiber reinforced prepreg cloth of toughened environment-friendly phenolic resin. Background technique: [0002] As one of the three thermosetting resins, phenolic resin has a development history of more than 100 years. Its remarkable features are low price, heat resistance, ablation resistance, flame retardancy, and less smoke when burning. With the development of electronics, machinery, transportation, etc. With the rapid development of transportation and national defense industry, phenolic resin and its composite materials have also been developed rapidly, but the weakness of ordinary phenolic resin is that hydroxyl and methylene are easily oxidized, and phenolic hydroxyl generally does not participate in chemical reactions in resin synthesis. There are many hydroxyl groups, and the phenolic hydroxyl group is a polar group...
