Self-Reinforced Composites as Advanced Materials for the 21ST Century

9979249 Nahr少数民族研究规划补助金中描述的项目将在18个月内进行。 它们主要关注聚合物加工过程中加工参数对微观结构发展的影响，特别是挤出混合和注塑成型-导致形成自增强的微米和纳米复合材料。 更具体地说，将开发实验和数值模拟方法，以评估液晶聚合物和柔性线圈热塑性塑料的共混物的加工过程中的工艺参数和形态发展之间的相互关系，后者作为基体聚合物。这种共混物通常被称为“原位复合材料”、“自增强复合材料”或“分子复合材料”，这些研究结果应成为制定有竞争力的研究提案的基础。 此外，它们将与本科生和研究生两级的教育活动以及广泛的辅导和外联活动密切结合。

9979249NahrThe projects described in this Minority Research Planning Grant will be conducted over an 18 month period. They are concerned principally with the effects of processing parameters on the microstructure development in polymer processing, in particular extrusion mixing and injection molding - leading to the formation of self-reinforcing micro-and nanocomposites. More specifically, experimental and numerical simulation methodologies will be developed to evaluate the interrelationships between the process parameter and morphology development during processing of blends of a liquid crystalline polymer and a flexible-coil thermoplastic, the latter serving as the matrix polymer. This blend is often referred to variously as "in-situ composites", "self-reinforcing composites", or " molecular composites".These research results should provide the basis for development of a competitive research proposal. In addition, they will be closely integrated with educational activities at both the undergraduate and graduate levels, as well as with extensive mentoring and outreach.
