Problems solved by technology

The temperature of the electric iron cannot be controlled, and it is easy to deform the fibers. The efficiency of ordinary scissors is low, and the cutting quality is poor. Many areas need to be cut twice, which increases the working time and reduces the lay-up quality of composite components.

Abstract

The invention provides a device for compacting and snipping a resin-based composite prepreg spread layer, and belongs to the technical field of forming and processing composite materials. The device comprises a supporting and shell mechanism, and a compacting mechanism, a heating mechanism and a snipping mechanism which are arranged in the supporting and shell mechanism; the compacting mechanism comprises a first roller and a second roller; the heating mechanism is arranged in the first roller and the second roller; the snipping mechanism comprises a pressing shim plate, a transmission mechanism of a circular saw and a circular saw blade; a circular saw blade dust absorption mechanism is also arranged in the supporting and shell mechanism; and the circular saw blade dust absorption mechanism is connected with a vacuum filter and a pipeline mechanism. The device can solve the problem that the prepreg cannot be completely attached to a mould due to different softening degrees of the prepreg when single small-size composite members are spread and the problems about spreading and snipping of a curvature radius area. Therefore, the vacuumizing time of the prepreg is greatly reduced, the production efficiency of the composite members is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to a resin-based composite material prepreg lamination compaction and notch device, which belongs to the technical field of composite material forming and processing. Background technique [0002] Resin-based composite materials, especially fiber-reinforced epoxy resin composite materials, have the advantages of high strength, light weight, heat resistance, corrosion resistance, fatigue resistance, good shock absorption performance, and good reliability. They are widely used in aerospace fields, electronic power , wind power generation, transportation and sports equipment and other fields. Prepreg is a prepreg sheet product made by impregnating reinforcing fibers (carbon fiber, glass fiber, aramid fiber) in a matrix (epoxy resin, polyester resin, thermoplastic resin, etc.), and is the intermediate of composite materials. Material. [0003] Due to the above-mentioned excellent properties of composite materials, different molding ...
