Abstract
Materials. The materials used in this research were T300/5208 unidirectional graphite/epoxy composite panels supplied by the Army Materials Technology Laboratory. The panels were in square form of 12 in. by 12. in. with nominal thicknesses of 0.042 in. (7-ply) and 0.144 in. (24-ply) respectively. All of the panels were subjected to c-scan examination for uniformity and integrity. The properties of the material are presented in Table 1. A schematic of the unidirectional composite is shown in Fig. 1.
