Abstract

The invention provides an experimental device and experimental method for testing the interlayer bonding performance of a prepreg.The experimental device comprises a body mechanism, a guide mechanism and a stripping mechanism, wherein the body mechanism comprises a base, a control cabinet, a speed control part and a pressure control part, the guide mechanism comprises an upper guide plate, a lower guide plate and a mounting support, the stripping mechanism comprises a tensile testing machine, an upper chuck and a lower chuck, and the upper chuck and the lower chuck are located in the middle hollow-out region of the tensile testing machine.The experimental device and the experimental method for testing the interlayer bonding performance of the prepreg can conform to the actual situations of automatic laying projects of large composite material members and provide a reliable basis for selection of process parameters in the automatic laying process.

Description

technical field [0001] This application relates to the technical field of automatic laying of conformable materials, in particular to an experimental device and an experimental method for testing the bonding performance between prepreg layers. Background technique [0002] Automatic laying technology is a low-cost composite material forming technology, including automatic tape laying technology (Automated Tape Laying, ATL) and automatic fiber placement technology (Automatic Fiber Placement, AFP), which integrates materials, structural design and manufacturing, and is highly integrated. CNC machine tool technology, material technology technology and CAD / CAM software technology have realized the processing capabilities of automatic laying, compaction, shearing and refeeding of prepreg materials, and are especially suitable for the production of large composite structural parts. In automatic laying technology, the selection of material system and the control of laying process a...
