(2) fiber on creel is passed sequentially through into collection yarn plate, layering yarn plate, steeping vat, preforming mould, mould, and is introduced Draw-gear；
(3) mould is heated up by temperature parameter requirement；
(4) resin, curing agent, accelerator, releasing agent and other auxiliary agents are mixed and stirred for uniformly by resin proportioning；
Etc. (5) after mould temperature equalization, the resin that will be prepared adds steeping vat, starts sheet material pultrusion operation；
(6) fiber point multilayer passes through steeping vat impregnation, through Extruded roller plastic squeeze step by step, the organdy of both sides and the upper demoulding after impregnation Cloth, bottom knockout cloth enter mould with fiber；
(7) after the sheet material after being molded cools through cool wind box, into draw-gear and wrap-up, as composite panel Material finished product.
The present invention can also be achieved by the following measures：Described curing agent is preferably liquid anhydride curing agent, accelerator Preferably tertiary amines accelerator, releasing agent is preferably epoxy type releasing agent.Resin proportioning is epoxy resin by weight percentage： Curing agent：Accelerator：Releasing agent=100：100~110：1.0~2.0：1.5~2.5.Roll coater in described steeping vat can It is divided into 2~6 layers, it is ensured that fiber fully infiltrates, by the plastic squeeze step by step of Extruded roller, preforming mould after fiber impregnation, Extruded roller, preformation Pattern is divided into 2~6 roads, fully to reduce the gel content of wet yarn before mould, and ensures that fiber is evenly distributed.Described mould Length is 800~1500mm, and it is solid to ensure sheet material to control the area of mould three or four area's solidification temperatures and post-curing oven temperature Change degree >=95%, interlaminar shear strength >=52MPa, 3rd area or four area's solidification temperature controls are in 160~200 DEG C, solidify afterwards temperature control System is at 140~180 DEG C.Described cool wind box is flat flow or vertical streaming, and length dimension is 1~2m, it is ensured that after sheet material depanning Quick cooling.Described draw-gear ensures sheet material pultrusion continuous and stable using caterpillar tractor, and pultrusion speed ensures 0.4~0.6m/min.The organdy quantity of described both sides is every side at least 1.Described upper release cloth, bottom knockout cloth material It is nylon or polyester.
The beneficial effects of the invention are as follows production method is easy to standardization, and production efficiency high, steady quality is adapted to criticize Amount continuous prodution.
Brief description of the drawings
