Hot-pressing jointing device for braided fiber reinforced composite plate

Abstract

The invention discloses a hot-pressing jointing device for a braided fiber reinforced composite plate. The hot-pressing jointing device comprises a rivet supply system, wherein the rivet supply system is matched and connected with an automatic rivet mounting system; a hot air heating system, a plate perforating system, the automatic rivet mounting system, a riveting system and a servo turntable system are arranged on a support frame; a jointing plate is arranged on the servo turntable system through a pneumatic clamping device connected to the servo turntable system; and along with the rotation of the servo turntable system, a joint is formed by sequentially heating a connected part by the hot air heating system, perforating the connected part by the plate perforating system, mounting a rivet by the automatic rivet mounting system and hot-pressing riveting by the riveting system. By using the hot-pressing jointing device, fiber damage caused in the jointing process of the braided fiber reinforced composite plate is reduced, meanwhile, automatic production is realized, and the jointing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of connecting composite material plates, in particular to a thermocompression connecting device for braided fiber reinforced composite material plates. Background technique [0002] With the application of composite materials more and more widely, especially the application of braided fiber-reinforced resin-based composite materials, the connection between composite materials and composite materials has become an important technical issue, such as: aircraft composite material structure More than 70% of the damage occurred in the joints, which shows that the joint technology has an important impact on the overall performance of the composite structure. Braided fiber-reinforced resin-based composites are divided into braided fiber-reinforced thermoplastic composites and braided fiber-reinforced thermosetting composites according to the characteristics of the resin. Braided fiber reinforced thermoplastic compo...

Problems solved by technology

However, the traditional Z-Pining connection is mainly used in the manufacturing process of composite laminates, and rigid short rods are directly embedded in the thickness direction of the prepreg or foam interlayer to improve the interlayer toughness, impact loss limit, and Properties such as compressive strength after impact, there are few examples of connection between parts

[0004] Usually the material of Z-Pining is a metal material, so there is electrochemical corrosion in the joint after connection, which reduces the connection strength of the joint, which requires the study of new materials for Z-Pining

In addition, because the traditional Z-Pining is an independent short rod, it is not conducive to the industrial mass application of composite material connection, so it is necessary to design a new Z-Pining structure
