Problems solved by technology

[0004] However, the existing technology cannot make the resin powder evenly distributed on the surface of the continuous fiber fabric, and the adsorption amount of the resin powder is limited and difficult to adjust, so that the obtained continuous fiber fabric reinforced thermoplastic composite sheet (board) has uneven weight and is easy to warp. The fiber content adjustment range is small, which limits the production of continuous fiber fabric reinforced thermoplastic composite sheets (boards)

Abstract

The invention discloses equipment and a method for producing a fabric-enhanced composite board. The equipment comprises a powder spraying device, a preheating device, a laminating device, a cutting device and a brake device, wherein the brake device comprises a plurality of uncoiling parts, a coiling part and a supporting roller; the supporting roller is arranged between the uncoiling parts and the coiling part; the powder spraying device comprises a plurality of powder spraying heads, the powder spraying heads are arranged between the uncoiling parts and the supporting roller, the number of the powder spraying heads is greater than the number of the uncoiling parts, and the powder spraying heads are respectively arranged between the adjacent uncoiling parts and at both sides of each uncoiling part. The equipment has the advantages that by arranging the powder spraying device, both surfaces of each layer of continuous fiber fabric are sprayed with resin powder, so that the impregnatinguniformity and operability of both sides can be well controlled, and the warp is effectively improved.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a fabric-reinforced composite plate production equipment and method. Background technique [0002] With the development of fiber-reinforced thermoplastic composites, continuous fiber-reinforced composites have been used more and more in practical applications due to their advantages of high strength and light weight compared with other composite materials. In particular, the continuous fiber fabric reinforced thermoplastic composite sheet (board) has relatively balanced tensile and bending properties in multiple directions, making it widely used in various fields. [0003] In the prior art, there are mainly two preparation methods for the continuous fiber fabric reinforced thermoplastic composite sheet (board). The first is the film lamination method. After the plastic is made into a film, it is laminated with a continuous fiber fabric, and sent to a pressing machine for heati...
