An incident involving unexpected collapse of a deck on a cruise linerhas been reportedto a regulator. Preliminary investigationpoints to possible problemsinstructural panels made of continuous and oriented fiber-reinforced composite.The quality of components needsto be checked to specification.Laboratory testing ofsamples fromthe composite panels revealed the moduli of elasticity in the longitudinal and transverse directions to be 25GPaand 5GPa, respectively. The volume fraction of fibers is 0.20. (a)Determine the moduli of elasticity of fiber and matrix phasesto help the investigation. (b)Besides the quality of individual components, what else could lead to the premature failure of continuous and oriented fiber-reinforced composites?
