The research involves the improvement of pitch-based carbon fibers used in construction of composite materials. Composites using various shaped fibers are formed, the compressive properties are tested, and comparisons made to predict optimum fiber shape. Matrex stress analyses for each fiber shape are considered theoretically. The buckling load and moment of inertia of the fibers are determined experimentally. The matter of fiber formation is emphasized. All fibers are produced by the same method and under the same conditions- melt spinning. The experimental portion requires chemical processing combined with mechanical testing. This project is one supported under the Creativity Awards for Undergraduate Engineering Students.

该研究涉及沥青基碳纤维在复合材料结构中的改进。使用不同形状的纤维形成复合材料，测试压缩性能，并进行比较以预测最佳纤维形状。从理论上考虑了各种纤维形状的基体应力分析。实验确定了纤维的屈曲载荷和转动惯量。强调纤维形成的问题。所有的纤维都是用同样的方法在同样的条件下生产的——熔融纺丝。实验部分需要化学处理和机械测试相结合。本项目为“工科本科生创意奖”资助项目。
