Engineering Creativity Award: Improved Pitch-based Carbon Fibers

这项研究涉及用于复合材料建筑的沥青基碳纤维的改进。用不同形状的纤维制成复合材料，测试了其压缩性能，并进行了比较，以预测最佳的纤维形状。从理论上考虑了每种纤维形状的Matrex应力分析。通过实验确定了纤维的屈曲载荷和转动惯量。强调了纤维形成的问题。所有的纤维都是在相同的条件下用同样的方法生产的--熔融纺丝。实验部分需要化学处理和机械测试相结合。这个项目是工科本科生创造力奖的资助项目。

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.
