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

Abstract

A hot-pressing connection device for braided fiber-reinforced composite material plates, including a rivet supply system, a rivet supply system and an automatic rivet installation system for joint connection, a hot air heating system, a plate punching system, an automatic rivet installation system, a riveting system, and a servo turntable system for installation On the bracket, the connected plates are installed on the servo turntable system through the pneumatic clamping device connected to the servo turntable system. With the rotation of the servo turntable system, the connected parts are heated by the hot air heating system in turn, and the plate punching system For the piercing holes of the connected parts, the rivet automatic installation system installs the rivets, and the riveting system performs hot-press riveting to form the connection joints. The invention reduces the damage to the fibers during the connection process of the braided fiber reinforced composite material plates, and realizes automatic production at the same time , reducing connection costs.

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...
