Problems solved by technology

Although the FRP material provided by this method overcomes the defects caused by the glass cloth itself, the unique physical properties of the fiber itself are greatly weakened because the glass fiber is cut into powder

Abstract

The invention provides a method for preparing flame-retardant epoxy resin glass fiber reinforced plastics, which comprises the following raw materials in parts by weight: 70-90 parts by weight of epoxy resin, 10-15 parts of curing agent, 2-5 parts of release agent, 15-30 parts of filler, and toughening agent 5~10, diluent 2~5, reinforcing material 10~25, flame retardant 15~25. The flame-retardant epoxy resin FRP prepared by the invention has the characteristics of excellent mechanical properties, surface leakage resistance, good impact resistance and good flame-retardant performance.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a method for preparing flame-retardant epoxy resin fiberglass. Background technique [0002] FRP material is a material in which glass fiber reinforced materials are embedded in cured thermosetting resin or wrapped by it to form a composite structure. At present, most of the FRP materials used in the market are formed by resin-impregnated glass cloth materials. The method has a good wetting effect and the prepared glass fiber has a high content. However, due to the limitation of the volume and shape of the glass cloth, it is especially not suitable for products such as pipe joints, tee fittings, and elbow fittings, which are not easy to be uniformly compressed. In addition, the impact resistance of the FRP material prepared by this method is poor, and the laminated surface is prone to delamination. In order to solve the above problems, some researchers cut the glass fiber in...
