Investigation of Tensile Properties of FML Composite Due to Moistures Aging

Fiber-metal composites are polymer composites reinfored with fibers and metal sheets.  In this study, the tensile properties of CARALL (CarbonReinforced Aluminum Laminate with CFRP (Carbon Fiber Reinforced Polymer) under the influence of moisture are compared and studied experimentally and numerically by finite element (FE) method. According to ASTM-D3039 standard, six samples of CARALL and CFRP composite are made using manual lay-up and carbon fibers, 3001 resin, and T6-7075 aluminum sheet and also, the samples were stored in dry and moisture conditions for 14 and 25 days. ANSYS software is used to simulate and compare the results with experimental tests. Comparison of the results shows that the moisture reduced the tensile properties of the samples. Also, the elasticity modulus for the CFRP and CARALL samples in humid environment during 25 days reduces respectively as 47.3% and 56.8% in comparison with the dry environment.
