| Summary |
"This work was focused primarily on the manufacture of polymer matrix composites using renewable and recycled materials. Methods are explored to recover valuable carbon fiber in a usable form from scrap materials. A novel pyrolysis process was implemented at the University of Missouri-Rolla (UMR) composites laboratory. Sufficient usable carbon fiber was recovered from scrap to allow new part fabrication and preliminary physical properties testing of this new material. Results were compared to those obtained using low cost virgin carbon fibers commonly used in compression molding applications. This work also describes the testing of new resin systems developed from soybean oil in the pultrusion process. Both neat resin test panels and pultruded carbon fiber/epoxy rods were produced to allow mechanical characterization of these new products. Preliminary mechanical testing of the neat resin and pultruded parts indicate that the resin system can be used to manufacture composite products by pultrusion. Resin properties such as viscosity and pot life remain well suiuted for pultrusion. Resin reactivity was only slightly decreased"--Abstract, leaf iv. |
