Abstract

The increasing demand for high-performance polymer-derived composites with improved stiffness-to-weight and strength-to-weight ratios requires significant research efforts for the implementation of multiscale computationally-driven design and manufacturing. Processing can lead to substantial residual stress build-up, which can compromise laminate strength and generate undesired residual deformations. Fortunately, cure-cycle parameters (cure temperature, hold times, ramp rates) can be optimized through computational process modeling techniques to reduce process-induced residual stresses. Advances in process modeling are crucial to Integrated Computational Materials Engineering (ICME), an emerging branch of mechanics intended to transform the design and manufacturing paradigm of advanced structures, and drastically reduce engineering time and cost through computationally-driven approaches. This talk will highlight multiscale process modeling techniques to understand the influence of processing parameters on polymer-derived composite performance in aerospace, automotive, and wind energy applications.
