Fiber-reinforced resin sheet molding device

Abstract

The invention relates to a fiber reinforced resin sheet material molding device, comprising a thermoplastic resin thin film unreeling mechanism, a fiber enhanced fabric unreeling mechanism, a guide roller transmission mechanism, a hot-pressing mechanism, a cooling mechanism and a traction driving mechanism, wherein the guide roller transmission mechanism is used for transmitting thermoplastic resin thin films and fiber enhanced fabrics, which are arranged at intervals in an overlapping manner together; the hot-pressing mechanism and the cooling mechanism are arranged on a transmission path and are used for molding the thermoplastic resin thin films and the fiber enhanced fabrics in a compound manner; and the traction driving mechanism is used for transmitting a sheet material after compound molding. The fiber reinforced resin sheet material molding device provided by the invention can conveniently, rapidly and continuously produce the anti-impact and anti-wear fiber reinforced resin sheet material.

Description

technical field [0001] The invention relates to a production device for fiber-reinforced composite sheets. Background technique [0002] The composite sheet is mainly made of thermosetting resin and fibers with various textures and colors. Composite sheet products made of thermosetting resins have high rigidity, but poor impact resistance. After the surface of the resin is impacted by sharp foreign objects, the resin is easily broken, which will cause permanent damage and reduce the aesthetics of the product. In addition, the production cycle of composite sheet products made of thermosetting resins is very long. In the production process, the long curing time and secondary curing time directly limit the output of this product. [0003] At present, when some enterprises produce composite sheets, they use film-coated plastic sealing technology to realize the bonding and molding of fiber substrates and resin films by coating methods. Since the bonding strength between layers d...

Problems solved by technology

Composite sheet products made of thermosetting resins have high rigidity, but poor impact resistance. After the surface of the resin is impacted by sharp foreign objects, the resin is easily broken, which will cause permanent damage and reduce the aesthetics of the product.

In addition, the production cycle of composite sheet products made of thermosetting resins is very long. In the production process, the long curing time and secondary curing time directly limit the output of this product

[0003] At present, when some enterprises produce composite sheets, they use film-coated plastic sealing technology to realize the bonding and molding of fiber substrates and resin films by coating methods. Since the bonding strength between layers depends on the resin film, adhesive and fiber The base material, the adhesive strength is difficult to guarantee, and there will be tiny gas between the layers. After a long time of use, there will be interlayer delamination, cracking, etc., and the service life is not long
