这是一个奖项，以支持研究的建议， 回收有价金属和增强的可行性 金属基复合材料（MMC）的组成部分，以便 消除不必要的惰性微粒的环境排放 和有害的金属浸出物。 热电偶 将评估铝和镁基质MMC的再处理 一个新的流程图将被设计为适应独特的 处理技术 最终将带来两大好处 复合材料回收工艺的商业化。 一是 潜在的严重环境危害源将被消除， 直接在来源地对复合废料进行再加工。 第二，贵重金属和高强度钢筋都将被 有效地再加工成新的复合结构， 整体节省人工、材料、能源和成本。 这项研究与环境工程计划是一致的 目标. 调查人员有很高的资格进行调查， research. 该提案是对SBIR第一阶段计划的回应 公告NSF 86-19。 从1987年2月1日起的6个月内， 推荐

This is a recommendation for an award to support research on the feasibility of recovering the valuable metallic and reinforcing components of metal-matrix composite (MMC) materials in order to eliminate the needless environmental releases of fine inert particulates and harmful metal leachates. PyrometallurgicaI and electrometallurgicaI reprocessing of aluminum and magnesium matrix MMC's will be evaluated and a new flowsheet will be designed to accommodate the unique processing technology. Two major benefits will result from the eventual commercialization of a composite recycling process. First, a potentially severe source of environmental hazard will be eliminated by reprocessing composite scrap material directly at the point of origin. Second, both valuable metals and high strength reinforcements will be efficiently reprocessed into new composite structures resulting in overall savings of labor, materials, energy and cost. This research is consistent with the Environmental Engineering program objectives. The investigators are highly qualified to carry out the research. This proposal was in response to SBIR Phase I Program Announcement NSF 86-19. An award of $40,000 for six months starting February 1, 1987 is recommended.
