A Guide to Modeling Thermoplastic Composite Manufacturing Processes

Download or read book A Guide to Modeling Thermoplastic Composite Manufacturing Processes written by Corey Lynam, P. Eng., and published by DEStech Publications, Inc. This book was released on 2014-09-09 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Models and experiments for faster, less expensive manufacture of thermoplastic partsFocused on simulating thermal defects in thermoplasticsTechniques for better molds, tooling and equipment Book explains methods and coding to create FEM-based models to optimize process variables and predict dimensional distortions during the manufacture of thermoplastic matrix composite parts. After investigating defects, such as spring-in, caused by thermal inconsistencies during manufacture, the text offers a step-by-step approach to simulating and predicting the magnitude of distortion via readily available FE codes. Models are validated by testing using the example of a multi-staged roll-formed continuous thermoplastic woven laminate, which can be readily extended to a variety of mold geometries. Information in this book is intended to reduce the need for costly and time-consuming re-tooling in thermoplastic parts design.
