The Experimental Study on the Mechanical Properties of Fiber-Reinforced Metal Laminates Using an Innovative Heat-Solid Integrated Forming Technology

In the forming process of fiber-reinforced metal laminates (FMLs) product, exploratory compound technology, including hot stamping aluminum alloy and laying fiber prepreg which is named HFQ-FMLs was proposed to solve puzzles such as weak rigidity, low strength integration deformation with large difficulty, feasibility mechanical properties innovative were studied. Firstly, based on modified volume fraction formula, theoretical values plates calculated. Compared experimental results, minimum error 1%, proving that technology scheme feasible. Secondly, three kinds sheets different heat treatments specimens by carried out for tensile tests, distributions demonstrated, influence regularity strain rate rolling direction stress analysis considered at same time. As can be seen from distribution yield strength, obtained along 45° superior raw material increase 46% under = 0.01 s−1. While, because vacuum thermal curing treatment makes happen double aging, sheet dropped, jointing between became too, made limit new improve weakly. Thirdly, fractured style FMLs conditions studied qualitatively. It helpful achieve development rule defects, optimize craft route, avoid failure.
