Embodiment 1

[0024] Mix glass fiber and wheat straw fiber according to the ratio of 70:30, then fully infiltrate with bisphenol A type epoxy resin of 5% by weight of the product, and dry it; the glass fiber is a monofilament diameter of 11 μm, 100 / bundle of monofilament bundled chopped glass fibers; the wheat straw fibers are wheat straw filaments with a length of 7 mm and a diameter of about 0.2 mm, and have been dried. This proportion can reduce the product weight by about 57% and the product cost by about 35%.

Embodiment 2

[0026] Mix glass fiber and wheat straw fiber according to the ratio of 70:30, then fully infiltrate with 3% vinyl resin of the product weight, and dry it; Chopped glass fibers bundled with filaments; the wheat straw fibers are wheat straw filaments with a length of 7 mm and a diameter of about 0.2 mm, and have been dried. This proportion can reduce product weight by about 57% and product cost by about 37%.

Embodiment 3

[0028] Mix glass fiber and wheat straw fiber according to the ratio of 60:40, then fully infiltrate with bisphenol A type epoxy resin of 5% by weight of the product, and dry it; the glass fiber is a monofilament diameter of 11 μm, 100 / bundle of monofilament bundled chopped glass fibers; the wheat straw fibers are wheat straw filaments with a length of 7 mm and a diameter of about 0.2 mm, and have been dried. This proportion can reduce the product weight by about 64% and the product cost by about 39%.

Abstract

The present invention relates to a glass fiber / wheat straw fiber short-cut felt. Its composition includes glass fiber and wheat straw fiber, the weight mixing ratio of glass fiber and wheat straw fiber is 60:40 to 85:15, in which the dose of synthetic resin is 3%-5% of total weight. Its preparation method includes the following steps: mixing glass fiber and wheat straw fiber, pressing them to make felt, impregnating said felt with synthetic resin and drying so as to obtain the invented product.

Description

technical field [0001] The invention relates to a composite material and a processing technology thereof, in particular to a chopped strand mat composed of glass fibers and wheat straw fibers, and a preparation method of the chopped strand mat. Background technique [0002] Glass fiber chopped strand mat is a main glass fiber non-woven reinforcement material, which is the most used reinforcement material in the FRP (glass fiber reinforced polymer) hand lay-up process, and is also widely used in mechanical forming processes such as winding and molding. . At the same time, the use of glass fiber chopped strand mat and roving grid cloth at the same time can also make up for the shortage of the grid cloth in only two directions of warp and weft, and effectively improve the interlayer shear of FRP (glass fiber reinforced polymer) products. cutting strength. [0003] However, due to the strong polarity of the glass fiber surface, the interface compatibility between it and the or...
