Abstract
The failure mode behavior of hybrid thin laminates consisting of Carbon Fiber Reinforced Plastic and Steel Plate Cold Commercial (CFRP-SPCC) in term of quasi-static tensile test was observed. The different fundamental failure mechanisms of fiber breakage, layer delamination, and matrix damage are discussed. The results from the experiment are compared with Finite Element Analysis (FEA) using Hashin failure criterion, and considered for more in-depth analysis using surface morphology of the [SPCC/±45/0]S specimen. The experimental results show that hybrid laminates can delay the premature fiber breakage and delamination of the laminates as well as increase the strain at the maximum stress up to 16%. The numerical model using FEA software showed Residual Thermal Compressive (RTC) stress and strain had a significant effect on the increased of strain performance in hybrid laminates due to the difference of Coefficient of Thermal Expansion (CTE) value between SPCC and CFRP.
