FINITE ELEMENT ANALYSIS OF LAMINATED HYBRID COMPOSITE PRESSURE VESSELS

In the present work an attempt has been made to numerically investigate the response of the hybrid composite material in different load conditions. Here a pressure vessel made of hybrid composite was chosen and analyzed by using the finite element simulation software Ansys workbench with ACP module. Two cases of hybrid composite materials are considered. Each case will contain 8 layers of composite material aligned in 0 deg direction. In the first case, each 4 layers are considered as one set and in the second case each two layers are considered as one set. E-glass, S-glass, Kevlar and graphite fibers with epoxy material were chosen as composite material. Static structural, free vibration and buckling analysis were performed. In view of these three analysis best composite combination was recommended.
