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.

9979249纳尔本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。他们主要关注加工参数对聚合物加工过程中微结构发展的影响，特别是挤出混合和注射成型--导致自增强微米和纳米复合材料的形成。更具体地说，将开发实验和数值模拟方法来评估液晶聚合物和柔性盘管热塑性塑料(后者作为基质聚合物)共混物加工过程中工艺参数和形态发展之间的相互关系。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”。这些研究结果应该为开发具有竞争力的研究方案提供基础。此外，它们将与本科生和研究生的教育活动以及广泛的指导和外联活动密切结合。
