The primary objective of research is to determine the improved structural efficiency of plates can be with variable fiber spacing. The Post-buckling of laminated composite plate with variable fiber spacing is obtained numerically, using eight node isoparametric quadrilateral elements (serendipity element) with five degree of freedom per node. The mathematical formulation is based on first-order shear deformation theory and von-Karman non-linearity. The effect of the initial geometric imperfection, fiber spacing, orientation fiber, and direction of in-plane loading were considered. Numerical results for boron/Epoxy fiber reinforced laminates are presented for the different effects of the composite plate under in-plane loading. This study showed that the post buckling behavior of composite plate very sensitive for type of distribution fiber and the seventh distribution equation gives maximum buckling load and smallest deformation.

Composite laminate design is an important procedure in defining the mechanical properties of laminated composite structure to be used in multi-directional service loading application. Composite technologies or manufacturers who is lack of knowledge regarding the importance of laminate design, tend to develop a composite structure that will collapse or fail below the service requirement. The purpose of this study is to determine the effect of fiber orientation on flexural properties of the designed glass fiber reinforced epoxy laminated composite. Six sets of laminates with different fiber orientation and sequence were simulated using CompositeStar© software to determine its flexural properties. Samples were fabricated to verify the simulated data and were tested in accordance to ASTM D2344. Moreover, crack pattern within the samples after the flexural test is studied. From the simulated results, it shows that laminates which have fiber in tri-direction and quasi-direction display a higher flexural modulus and strength compared to laminates with fiber in uni-directional and bi-directional. In addition, data from tested fabricated laminates samples displayed the same modulus patterns against the simulated data, with variants from 8% to 35%. Additionally, it is found that samples with fiber in ±45 direction shows a transverse and shear cracking which prolonged the cracking propagation before the samples show a complete failure.
