Abstract

The invention discloses a method and a device for manufacturing resin-based composite material component by using fiber placement technology. By adopting fiber placement technology, the method and the device can place a fiber placement layer on the surface of a core die by a compaction mechanism to solve the problem of conventional winding equipment that is incapable of manufacturing surface component with negative curvature and non-gyrorotor component. Meanwhile, in-situ instantaneous stratified radiation curing is adopted to eliminate the influence of a tensile force in the fiber placement layer on the shape of the product and to solve the problems and disadvantages of large thermal deformation and easy generation of cracks due to autoclave curing treatment, the restriction of the autoclave volume on the component size, high production cost, and long production period. Based on industrial robot as the manufacture body, the device can improve the problems of prior placement equipment such as the deficiency of the flexibility in manufacturing more complex surface and complex structure.
