The Impact Resistance of Thermoplastic Fiber-metal Laminates Based on Glass and Basalt Fibers

摘要

In an attempt to reduce the elevated processing temperature and pressure required fora prolonged period for consolidation of components made from prepreg in conventionalfiber metal laminates (FMLs), thermoplastic matrix FMLs, known as TFMLs, haverecently been introduced. The present work is an experimental study on the low velocityimpact response of a TFML based on thin layers of an aluminum alloy and apolypropylene (PP) matrix reinforced with basalt fibers. The response of the TFMLbased on basalt fibers under low velocity impact loading is evaluated, where the effect ofvarying the stacking configuration of the constituent materials is studied, with the resultsbeing compared to those offered by glass fiber/PP reinforced FMLs, basalt/epoxyreinforced FMLs and neat aluminum. The results show that basalt TFMLs behaved betterthan aluminum plates and glass TFMLs, especially for the energy level causing FC (firstcrack) due to a greater deformation ability of basalt fiber metal laminates.
