The purpose of this research was to further develop the technology for low-cost carbon fiber production for a variety of commercial applications and to make recommendations based upon the findings of this research. Major research objectives were to: Demonstrate production and characterization of low-cost carbon fibers, including installing and testing all fiber spin lab equipment; procuring furnaces for heat treatments (dry, stabilization, and carbonization); characterizing carbon yield, fiber diameter, uniformity, microstructure, and surface modification; and evaluating the relationship between processes and fiber micro-structure and its physical/mechanical properties; and to Demonstrate fabrications and characterize composites made from low-cost carbon fiber. The purpose of this effort was to assess the potential for a wide range of composite applications for the low-cost carbon fibers, including fabricating different fiber forms, evaluating different processes for fabrication of the carbon fiber composites, and investigating the effects of matrix, fiber forms, fiber surface treatments, hybrid fibers, and additives on the physical and mechanical properties of the prepared composites. |
