Effect of fibre waviness on compression failure of cross-ply carbon/epoxy laminates
Апстракт
Composites were made as cross-ply laminates with artificially introduced waviness near the middle, with different severity of waviness and different fractions of wavy layers. The laminates had configuration (0/(90 0(2))(n) /core/ (0(2) 90)(n)/ 0) with n = 2, 4, and 6 in samples with 24, 36, and 48 layers respectively. The fraction of wavy layers varied from 6 to 37%, and the severity of waviness, measured as the ratio of amplitude over half wavelength - 2a/lambda, varied from 0.03 to 0.08, which corresponded to the angular deviations from 7 to 14 degrees. The composites were tested in compression to determine the effect of wave severity and fraction of wavy layers on compression strength. Failure of tested coupons was examined to establish the mechanism of fracture initiation and propagation. Two compression failure mechanisms were observed.
