小行星9409963 该奖项旨在研究和模拟控制复合材料制造中用作预制件的2D和3D纺织机织物变形行为的基本物理机制。 将进行模型实验，以量化各种约束条件下的局部晶胞行为，并确定各种编织图案的纤维屈曲的临界应变条件。 这些实验的结果将被纳入一个单元模型，可用于预测复杂零件形状的一致性质量。 该研究旨在建立科学的设计准则，以更有效地使用纺织品预成型件。 从研究中获得的见解可能会导致开发新的，创新的，强大的方法，用于大批量制造复合材料零件。

9409963 Chen The award is for research to understand and model the fundamental physical mechanisms which govern the deformation behavior of 2D and 3D textile woven fabrics used as preforms in composite manufacturing. Model experiments will be conducted to quantify local unit cell behavior under a variety of constraint conditions and to determine critical strain conditions for fiber buckling for various weave patterns. Results from those experiments will be incorporated into a unit cell model that can be used to predict quality of conformance to complex part shapes. The research is directed toward the establishment of scientific design guidelines for more efficient use of textile preforms. Insights gained from the research are likely to lead to the development of new, innovative, and robust methods for high volume manufacturing of composite parts.
