Abstract

The invention relates to a glass reinforced plastics air pressure forming manufacturing method. It can effectively solve the problem that both sides of the glass reinforced plastics product is gabrous, especially the big internal mold cavity, and small collar extension. The technical proposal are that resin and fiber are coated between the hard outer mold and the soft inner mold; after sealing the mold gland is fixed and aerated to increase pressure; or after air proof hold down strip is sealed, the inner and outer mold are set in the pressure container to aerate, increase pressure, and solidify. The invention can solve the pressing problem which can not be solved by the existing pressure forming technology, which means no matter how complicate the shape of the product is, it still can make the both sides of the product be gabrous. Its advantages are that the manufacturing technique is unique; the effect is good; the quality of the product is good; the appearance is beautiful; the market is wide; and the economic benefit is notable.

Description

1. Technical Field

[0001] The invention relates to an air pressure forming method, in particular to a FRP air pressure forming manufacturing method for producing FRP products. 2. Background technology

[0002] At present, the commonly used glass fiber reinforced plastic molding methods include hand lay-up molding, compression molding, casting molding and winding molding methods (processes). The above-mentioned molding methods have complex and strange shapes, especially products with large inner mold abdominal cavity and small outer diameter. The product has a smooth and flat appearance on both sides (inside and outside), which greatly affects the quality, use value and sales of the product, and affects the production and development of FRP. Third, the content of the invention

[0003] In view of the above situation, the purpose of the present invention is to provide a new manufacturing method (production process) of FRP gas pressure forming, which can effectively solve the probl...
