摘要

Fiber–metal laminates (FMLs) including glass and basalt fibers were manufactured in five various laminates sequence by the hand lay-up method, as a new technique. Then, their flexural behavior was investigated versus the stacking sequence and cryogenic cycles. Every cycle was carried out for 4 min between – 100°C and 25°C. Scanning electron microscopy and optical microscopy were used to characterize the failure mechanism of the specimens. The largest flexural strength values belonged to the FML samples containing basalt fibers (BFML), and these samples had the highest changes in the values of flexural properties while the lowest changes were for the glass fiber samples. In other words, the enhancement value of the modulus, flexural strength, flexural modulus, and strength of the BFML samples were about 5%, 6.2%, 1.63% and 2.4%, respectively. In fact, an enhancement in flexural behavior was observed when the hybrid FMLs were subjected by cryogenic cycles.
