Impact behavior of hybrid composite plates dependent on curing and different stacking sequences

In this study, the drop weight impact response of cured hybrid composite plates has been investigated. Experiments were conducted on two groups of hybrid composite plates. The first group was based on upper and lower surfaces that are made of carbon (c) with the inner plates of glass (g), while for the second group the upper and lower surfaces were examined which are made of glass (g) with the inner plates of carbon (c). The orientation angle of the plates was 0, 15, 30 and 45 degrees and the collision energy was 12 J. Contact forces were obtained and compared for the plates with respect to the different sequence and orientation angles. Peak forces increased for all the sequences and orientation angles. However, the (g-c-c-g) stacking sequence showed a larger sensitivity to an orientation angle change. The deflections decreased for the (c-g-g-c) stacking sequence when the orientation angle increased.
