摘要

Utah State University has recently developed a low cost, "green" hybrid rocket technology based on a form of additive manufacturing known as fused deposition modeling (FDM). To date all of the hybrid fuel applications have relied upon commercially available feed stocks optimized for structural properties. Generally, commercial feed-stocks are suboptimal for propulsion applications. By blending various plastics, there exists considerable potential to enhance the burn characteristics of the printed hybrid rocket fuel. Blending of polymers to form enhanced-property alloys is more complicated than just throwing the materials together into a melting pot. Seldom do different types of polymers blend well together. Polymers that do not mix well together are referred to as immiscible. The plastics most useful for propulsion applications including Acrylonitrile Butadiene Styrene (ABS) and Low-Density Polystyrene (LDPE) are immiscible, requiring special processes to obtain usable product. Elaborations on this process are presented in this paper. The fabrication of standard grain shapes using these two plastics and their alloys are explained. The results of burning them and their mixes are analyzed.
