Abstract

The invention relates to an electron beam curing LOM forming method and device of thermosetting resin matrix composites. A composite prepreg tape coil is arranged on a coil release roller, and conveyed to a multipoint support plate through a conveyor device; a composite prepreg tape is cut by a laser emitter; the composites properly cut are transferred to a semi-finished part through a first manipulator, heated by an infrared heat lamp, hot-pressed by a press roller, and finally cured by low energy electron beam irradiation through a low energy electron beam emitter, so that the molding of a layer is finished; and the above steps are repeated till the molding of the required parts is finished. The electron beam cured thermosetting resin matrix adopted by the device is resistant to corrosion and high temperature, excellent in insulation and adhesive properties, and high in strength, and the LOM technology is high in forming speed, free of warping, and small in deformation with no need of support. According the method provided by the invention, the forming size is unlimited, and the selection of fiber bundle materials is wide; and the thermosetting resin matrix is excellent in performance, and the fiber directions can be arranged according to the design requirements.

Description

technical field [0001] The invention mainly relates to the technical field of thermosetting resin-based composite material molding, and in particular to a thermosetting resin-based composite material electron beam curing LOM molding method and device. Background technique [0002] Composite components have many advantages such as high specific modulus, high specific strength, fatigue resistance, corrosion resistance, good shock absorption, and designability, and play a unique role in many aspects such as metal substitution, energy saving and emission reduction, and special materials. . [0003] Epoxy resin is a thermosetting polymer material with good corrosion resistance, insulation performance and adhesive performance. However, after curing, the substance is brittle, and its impact resistance and crack resistance are relatively low, which limits its further application and development. The fiber-reinforced thermosetting resin-based composite material made of epoxy resin a...
