Abstract
The A17075/CFRP multi-layered hybrid laminate material consists of the alternating A17075-T6 sheets and carbon/epoxy prepregs of M40 fade. The influence of volume fraction and fiber orientation of A17075/CFRP layer on flexural properties of A17075/CFRP laminate alternating A17075-T6 and carbon/epoxy prepreg was investigated. The results obtained from the experimental analysis are as follows: 1. In the fiber orientation, the mont of increase of the flexural rigidity was at the volume fraction and volume fraction compared with the flexural rigidity level(20.0GPa) of the volume fraction of CFRP. 2. In the fiber orientation the amount of decrease of the flexural rigidity was volume fraction and volume fraction compared with the flexural rigidity level of the volume fraction of CFRP. 3. In the fiber orientation, the flexural strength was 481.5MPa at the volume fraction of CFRP and 583.8MPa at the volume fraction and 653.7MPa at the volume faction. 4. In the fiber orientation, the flexural strength was 354.0MPa at the volume fraction of CFRP and 340.5MPa at the volume fraction.
