9409963陈，该奖项是为了研究了解和模拟2D和3D纺织机织物在复合材料制造中用作预制件的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单胞行为，并确定不同组织模式下纤维屈曲的临界应变条件。这些实验的结果将被合并到一个单元细胞模型中，该模型可以用于预测复杂部件形状的一致性质量。这项研究旨在建立科学的设计指南，以便更有效地使用纺织品预制件。从研究中获得的见解可能会导致开发新的、创新的和强大的方法，用于大批量制造复合材料部件。

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.
