Abstract

The invention discloses a preparation method and device for a continuous-filament woven fabric reinforced thermoplastic composite. The device mainly comprises an unwinding device (1), a pretensioningdevice (2), a fabric pretreatment device (3), a preheating device (4), a dipping mold (5), a connector (6), a screw machine (7), a forming device (8), a cooling pulling device (9), a winding device (10), continuous-filament woven fabrics (11) and dipped continuous-filament woven fabrics (12). The filament woven fabrics or fiber yarns subjected to dispersion treatment are subjected to pulling, surface treatment, drying, sufficient dipping with resin in the dipping mold and winding after being cooled and formed, and required products are obtained. The one-step forming technology is achieved, equipment investment is reduced, the production efficiency is improved, and the product quality is stable. The connector (6) and the dipping mold (5) are arranged flexibly, and one-step forming of two-layer or even multilayer filament woven fabric composites can be achieved.

Description

technical field [0001] The invention relates to the field of preparation of continuous fiber reinforced thermoplastic composite materials, in particular to a preparation method and equipment for continuous fiber fabric reinforced thermoplastic composite materials. Background technique [0002] Continuous fiber reinforced thermoplastic composites have many performance advantages. Compared with discontinuous fiber-reinforced composite materials, its mechanical strength has hundreds of times the advantage; compared with thermosetting fiber-reinforced composite materials, its advantages in environmental protection are self-evident.
