ABSTRACT

Fiber reinforced composite laminates consist of basically two different materials: glass and resin. These two are combined in many different ways such as short fiber mats, long fiber woven rovings and unidirectional filament windings. These layers can have very different thermal expansion coefficients. In addition, the thermoplastic liner also has different thermal expansion coefficients from the FRP layers. The difference in expansions can give rise to severe stresses in the different layers. This problem is realized by designers but limited work has been done because of the complexity of the problem. Thermal stress analysis will be addressed in this chapter.
