Problems solved by technology

Epoxy resin has the characteristics of excellent physical, mechanical and electrical insulation properties, corrosion resistance, chemical stability, bonding performance with various materials, and the flexibility of its use process, etc., and is widely used in the preparation of composite materials, but Epoxy resins are brittle, have poor impact resistance, are easy to crack, and are not resistant to aging, etc. These defects largely limit their application in occasions that require aging resistance, high impact resistance and fracture resistance

Abstract

The invention discloses a fiber-reinforced biological resin adhesive composite material and a preparation method thereof. The composite material is prepared from 10-50 parts by weight of a biological resin adhesive and 50-100 parts by weight of fibers. The biological resin adhesive is prepared from 20-100 parts by weight of biomass oil-modified epoxy resin, 2-20 parts by weight of a diluent, 1-4 parts by weight of an emulsifier, 1-3 parts by weight of a coupling agent, 1-5 parts by weight of a release agent, 5-20 parts by weight of a filler, 1-4 parts by weight of a pigment and 10-20 parts by weight of a curing accelerator. The biological resin adhesive is prepared from the biomass oil-modified epoxy resin, then infiltrates fibers and then is cured so that the fiber-reinforced biological resin adhesive composite material with better toughness, better weather resistance and excellent mechanical properties is obtained. The method is used to prepare the composite material, utilizes easily accessible and cheap raw materials, has simple and mature processes and reduces a composite material cost.

Description

technical field [0001] The invention relates to the technical field of composite materials and production thereof, in particular to a fiber-reinforced biological resin glue composite material and a preparation method thereof. Background technique [0002] Fiber-reinforced composite materials are composite materials formed by reinforcing fiber materials and matrix materials through hand lay-up, winding, molding or pultrusion. According to different reinforcing materials, common fiber reinforced composites are divided into glass fiber reinforced composites, basalt fiber reinforced composites, carbon fiber reinforced composites and aramid fiber reinforced composites. Fiber-reinforced composite materials have the following characteristics: (1) high specific strength and large specific modulus; (2) material properties can be designed; (3) good corrosion resistance and durability; (4) thermal expansion coefficient is similar to that of concrete . These characteristics make fiber...
