Abstract: Fiber reinforced polymer composites are rapidly attracting an increasing market share in a number of leading industries including aerospace, automotive, marine, and sports equipment. In particular, recent developments in fabricating advanced textile fiber reinforcements and resin materials, as well as new rapid manufacturing processes, have now allowed polymer matrix composites to be a competitive alternative to several traditional materials. A traditional challenge during processing of composites, however, is the presence of large variations in the raw material along with propagating uncertainties during different stages of manufacturing. This in turn has posed a great challenge for composite manufacturers for quality control of their final products, especially when it comes to the development/use of new products/material options where less knowledge is available. This seminar, through a number of industrial case study examples, will discuss the current state-of-the-art and future challenges on integrating testing, multi-scale finite element modeling and optimization tools for (a) predicting and optimizing the material behavior of composites under diverse applications, and (b) identifying the main material, geometry, and processing factors that can have the largest effect on manufacturing quality variations.
