Abstract

The invention relates to the field of epoxy resin composite materials, and discloses an epoxy resin composite material which comprises epoxy composite substrates and continuous fibers formed in the epoxy composite substrates. The fineness of the continuous fibers is 1200tex or less, and the thickness between the surface of each epoxy composite substrate to the corresponding continuous fiber is higher than 12 micrometers. The invention further relates to a method for preparing the epoxy resin composite material, the epoxy resin composite material prepared by the method and an epoxy resin composite material product. The product prepared by the method has good metallization selectivity effect and high bending modulus, so that light weight can be achieved.

Description

technical field [0001] The invention relates to the field of epoxy resin composite materials, in particular to an epoxy resin composite material and product and a preparation method thereof. Background technique [0002] Patent application CN102337038A discloses a plastic composition, which contains a plastic substrate component and a catalyst component, and the plastic substrate component is a thermoplastic resin or a thermosetting resin. The thermosetting resin is one or more selected from phenolic resin, urea-formaldehyde resin, melamine-formaldehyde resin, epoxy resin, alkyd resin and polyurethane. The inorganic filler is selected from glass fiber, carbon fiber, tin oxide, etc., and the plastic sample is etched by irradiating energy rays, so that part of the plastic is gasified and stripped to expose the catalyst component particles; The samples were electroless copper plated. This technology is to prepare plastics by adding resin and chopped fibers, and post-injection...
