Process Modeling and Analysis Tools for Thermoplastic Composite Missile Structures (MSC P4082)
The primary objective of the proposed Phase II SBIR program is to demonstrate material modeling and process simulation tools for predicting properties of thermoplastic matrix composites (TPMCs) for next generation aviation and missile structures. In order to sufficiently characterize the influence of the material characteristics and processing conditions on structural properties, the proposed methodology is based on extensive material characterization, processing data, and mechanical testing of thermoplastic composite structures with representative geometry and fiber orientation. The work proposed for the Phase II program will build on the model development, process trials and experimentation performed in Phase I to extend the material/process modeling and property prediction to representative cylinders and missile structures. Development and demonstration of a methodology for material modeling and process simulation of compression molded thermoplastic composites will also be performed as part of the Phase II program. The material and process models will be integrated into a commercial finite element software code for improved structural analysis of thermoplastic composite structures. This will provide an improved understanding of the influence of processing parameters on material properties, lead to more efficient production of thermoplastic composites, and facilitate the implementation of TPMCs into future aviation and missile structures.
