Abstract

This paper focus on the investigation of tensile strength and thermal residual stress inUACS/Al laminates. The UACS (unidirectionally arrayed chopped strands) is made by cuttingparallel slits on unidirectional carbon fiber prepreg. Thus all of the carbon fibers in the cut prepregare 25 mm in length. Six cases of UACS prepregs are prepared with different slit angle θ, which isthe angle between slit and fiber direction, including 5.7°, 11.3°, 16.7°, 31°, 45° and 90°. A UACS/Allaminate consists of one UACS layer with four UACS plies and two aluminum layers, such as [Al/UACS4/Al]. Four pieces of UACS prepreg with alternate slit angle [θ/-θ/θ/-θ] are stackedtogether in the same fiber direction. Then the stacked UACS/Al laminate is cured using anautoclave. Tensile tests are performed to investigate the thermal residuals stress using yieldingpoint-shift method. Experiment results show that thermal residual stress is reduced in the case ofUACS/Al compared to conventional CFRP/Al. Among all the cases, specimen with slit angle of11.3o is the most impressive one with 37.7% reduction of thermal residual stress.
