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?

Mechanical Properties of Solids

There are three types of matter- solid, liquid and gas. Out of them, solids have a rigid shaped and size. The intermolecular forces of attractions in solids are greatest. Mechanical properties are the physical properties of a material which it shows, when it is provided with certain amount of force or load. These properties are to be kept in mind for various purposes. When a force is applied to an object, the object may or may not get deformed depending upon its elastic property. But every time the object develops a restoring force against the force applied. This is commonly known as stress. If the object changes its dimensions due to the force applied it develops strain ( which is the ratio of change in dimension to the original dimension).
