Environmental Hazard Control By Metal Matrix Composite Reprocessing

这是一项建议，以支持关于回收金属基复合材料中有价值的金属和增强成分的可行性的研究，以便消除不必要的细惰性颗粒和有害金属渗滤液的环境释放。将对铝和镁基MMC的火法冶金和电冶金再加工进行评估，并将设计一个新的流程以适应独特的加工技术。复合材料回收过程的最终商业化将带来两个主要好处。首先，通过直接在原产地对复合废料进行再处理，将消除潜在的严重环境危害源。其次，有价值的金属和高强度的增强材料将被有效地重新加工成新的复合材料结构，从而节省劳动力、材料、能源和成本。本研究与环境工程专业的目标一致。调查人员完全有资格进行这项研究。该提案是为了响应SBIR第一阶段项目公告NSF 86-19。建议从1987年2月1日起六个月奖励4万美元。

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.
