The impact behavior of hybrid composite plates cured at 120°C were examined by dropping weights on them for three hours. Two groups of hybrid composite plates were considered. In the first group (TYPE1), all plies were staked symmetrically or antisymmetrically with orientation angle 0°, but in the second group (TYPE2), plies were staked symmetrically or antisymmetrically with orientation angles 0° and 45°. The plates were subjected to impact loadings with energies of 12, 16, and 20 J. Deflections, contact forces, and absorbed energies were determined and compared for plates in the different groups.

不同能级冲击下混合复合板的损伤行为

在 120°C 下固化的混合复合板的冲击行为通过在它们上落下重物三小时来检查。考虑了两组混合复合板。在第一组 (TYPE1) 中，所有层都对称或反对称地放样，方向角为 0°，但在第二组 (TYPE2) 中，所有层都对称或反对称放样，方向角为 0° 和 45°。板承受能量为 12、16 和 20 J 的冲击载荷。 确定并比较不同组中的板的挠度、接触力和吸收能量。
