This Small Business Technology Transfer Phase I project will demonstrate feasibility a rapid, low-cost method of manufacturing continuous fiber-reinforced ceramic composites (CFCCs). CFCCs are a class of material whose tremendous market potential has been thwarted by their excessive cost, resulting from the current, inefficient manufacturing methods. Thor Technologies, Incorporated will team with Los Alamos National Laboratory (LANL) to integrate three technologies into a single efficient manufacturing process: (1) preceramic polymers; (2) high frequency microwave (HFMW) radiation; and (3) polymer infiltration/pyrolysis (PIP) processing. The HFMW-PIP process will produce CFCCs in a fraction of the time and at a fraction of the cost of current methods. Preliminary studies have mitigated the technical risk, and the potential for greatly enhanced productivity over current methods mitigates commercialization risk. The proposed effort will characterize the effects of HFMW radiation on the materials, will demonstrate process feasibility by manufacturing and testing coupons and simple shapes (tubes), and will assess the productivity and economic potential of the process. The Proposed PI has substantial experience with preceramic polymers and the PIP process, while our collaborators at LANL have extensive experience with HFMW heating. Thor Technologies has the managerial and financial resources to develop the process to full-scale production. A wide variety of industries, ranging from aerospace to the petroleum and chemical processing industry, would benefit from the availability of low cost materials that are stable under hot, oxidizing conditions, do not corrode, and weigh less than metals yet are strong and tough. Although their price has relegated CFCCs to small, niche market to-date, reducing their cost to the point at which they compete with metals, such as intermetallics and superalloys, will open substantial new markets. Applications in transportation and energy will result in increased productivity and a cleaner environment for the nation.

这个小型企业技术转移阶段项目将证明可行性是一种生产连续纤维增强陶瓷复合材料（CFCC）的快速，低成本的方法。 CFCC是一类材料，其巨大的市场潜力因当前效率低下的制造方法而受到过多成本的挫败。 Thor Technologies，Incorporated Will Will与Los Alamos国家实验室（LANL）合作，将三种技术整合到一个有效的制造过程中：（1）杂物前聚合物； （2）高频微波炉（HFMW）辐射； （3）聚合物浸润/热解（PIP）处理。 HFMW-PIP过程将在当前方法的一小部分和一小部分中产生CFCC。 初步研究降低了技术风险，并且高于当前方法的生产力大大提高了生产力，从而减轻了商业化风险。 拟议的努力将表征HFMW辐射对材料的影响，将通过制造和测试优惠券和简单形状（管子）来证明过程可行性，并将评估该过程的生产力和经济潜力。 拟议的PI在前陶瓷聚合物和PIP过程中具有丰富的经验，而我们在LANL的合作者在HFMW供暖方面具有丰富的经验。 Thor Technologies拥有管理和财务资源，可以开发全面生产的过程。 从航空航天到石油和化学加工行业的各种各样的行业将受益于在炎热，氧化条件下稳定的低成本材料的可用性，不腐蚀和重量低于金属，但又强大而坚固。 尽管他们的价格已将CFCC降级到迄今为止的小型，利基市场，将其成本降低到与金属竞争的地步，例如金属中的金属和超合金，但将开设大量的新市场。 运输和能源上的应用将提高生产率和更清洁的国家环境。
