TL;DR: In this article, a plane strain finite element model for simulation of the development of process-induced deformation during autoclave processing of complex-shaped composite structures is presented, where a "cure-hardening" mechanism is used.

TL;DR: In this article, the authors present an experimental study that shows that spring-in can be strongly affected by a number of factors such as cure cycle, tool surface, part geometry, and lay-up.

TL;DR: In this paper, an experimental study of the effect of process conditions and part aspect ratio on tool-part interaction induced warpage is presented. But the results of the study are embodied in an empirical relation, which can be a useful guide to predict laminate warpage over a range of industrially relevant conditions.

TL;DR: In this paper, a plane-stress continuum damage mechanics (CDM) based model for composite materials is developed and implemented in the commercial finite element code, LS-DYNA and the results of the application of the model to the prediction of impact damage growth and its effects on the impact force histories in carbon fibre reinforced plastic laminates are shown to be physically meaningful and accurate.

TL;DR: In this paper, the flow and compaction of angle laminates, manufactured with the autoclave process, was studied for two carbonepoxy composites (AS4/3501-6 and AS4/8552) under a wide range of bagging and molding conditions.
