Abstract

Composites distort during manufacture, causing difficulties assembling structures, and leading to increased costs. An interative approach to tool design is often used, with the geometry modified on a trial and error basis in order to produce the correct cured shape. In this chapter the fundamental mechanisms that cause the residual stresses producing these distortions are first considered. The ways in which these mechanisms cause distortion in flat plates and spring-in in curved composites are then considered, together with the ability of models to predict the changes in geometry. Finally distortion in more complex structures is discussed briefly. Much of the research that has been done on this topic has been for autoclave curing of thermosetting resins, but the same phenomena are directly relevant to other manufacturing processes.
