Title:
NATURAL PLANT FIBER/WATER-BORNE EPOXY RESIN COMPOSITE MATERIAL AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/179260
Kind Code:
A1
Abstract:
Disclosed in the present invention are a natural plant fiber/water-borne epoxy resin composite material and a manufacturing method therefor. The main components of the composite material are natural plant fibers, a water-borne epoxy resin and a curing agent. The method comprises: mixing natural plant fibers, a water-borne epoxy resin and a curing agent until uniform, subjecting same to drying, dehydration and pre-curing to prepare a prepreg, and then subjecting same to hot press molding to obtain a composite material. In the present invention, by means of the porosity and hydrophilicity of the natural plant fibers, the plant fibers and the water-borne epoxy resin are compounded, and the manufactured plant fiber/epoxy resin composite material has good mechanical properties. The present invention effectively solves the problems of poor interfacial compatibility and low mechanical properties of a composite material when plant fibers are directly compounded with an epoxy resin; the manufacturing method is simple and convenient; and no organic solvent or volatile organic compound (VOC) is released during the manufacturing and usage processes, and thus the present invention is green and environmentally friendly.
