Experimental and numerical analysis of CFRP-SPCC hybrid laminates for automotive and structural applications with cost analysis assessment

Abstract

The present study evaluated CFRP and SPCC hybrid laminates by combined experimental and simulation analysis. The results showed that the strength of hybrid laminate [SPCC/[0]n]S increased more than 100% from 1000 MPa (0.5 mm thickness) compared to 2000 MPa (2 mm thickness). Moreover, by setting the volume fraction of hybrid laminates, the strength can increase from under 500 MPa to more than 3000 MPa with a minimum changed in strain performance. In other results, the effect of temperature differences during the manufacturing process is investigated. The analysis related to the operational temperature that used different material combinations was also evaluated. The band of temperature is varying from as high as 45 °C to as low as −45 °C. The outcomes demonstrate that the range of maximum strain of laminate from 45 °C to −45 °C can up to 0.1% of strain. Further analysis with a comparison regarding the angle effect of hybrid laminates with residual compressive stress and the curing temperature was also evaluated. The waviness trend shows higher when the temperature is set higher, and vice versa. The experimental results indicate good agreement with simulation results. Moreover, the analysis based on cost assessment was included and compared with other mechanical properties.
