Abstract
In this article, an investigation of Young's modulus E, shear modulus G, Po isson's ratio v and bending rigidity D for a general class of randomly orie nted composite laminate is presented. A simple random statistical analysis has been used to demonstrate that the mean values of E, G, v and D in the r andomly oriented laminate are close to those analytical values obtained fro m the classical lamination theory. Also, the influences of the various lami na material properties E-2/E-1, G(12)/E-1 and v(12) to the values of E, G, v and D of the laminate are investigated. The results from this statistical analysis provide a set of general guidelines for designing the values of E , G, v and D of the randomly oriented composite laminates based on the give n values of the influence factors E-2/E-1, G(12)/E-1 and v(12).
