This Small Business Innovation Research (SBIR) Phase I project will develop and demonstrate a pultrusion-based continuous, automated, near net shape manufacturing technology. The technology may be able to reduce the finished cost of constant cross section carbon/carbon composite structures by an order of magnitude or more. The resulting change to accepted cost/performance paradigms arising from this revolutionary reduction in carbon/carbon price will open a wide range of new commercial markets that until now have been constrained by cost to using much lower-performance pyrolytic graphite. The research includes design and fabrication of a lab-scale, automated production line, plus process optimization runs and analytical characterization of the resulting carbon/carbon test samples. Key technologies to be demonstrated include the continuous matrix impregnation of moving dry carbon fiber preforms as they pass through the wet-out portion of the processing equipment, plus continuous in-line rigidization of a high char yield matrix. The resulting "green" composite is expected to be developable into a commercially viable high-density carbon/carbon part after a single carbonization cycle. Mechanical and thermal properties of the low cost carbon/carbon will be many times better than the current commercial materials this product will replace. Carbon/carbon has unique high temperature thermal and mechanical properties. A few large dollar-value markets that will eagerly accept and apply commercially-priced carbon/carbon components include heat treating furnace structures, steel-making electric arc furnace electrodes, fuel cell components, heat exchangers, thermal radiators and crucibles.

这项小型企业创新研究（SBIR）I阶段项目将开发并展示基于脉冲的连续，自动化，近乎净形制造技术。该技术可能能够减少恒定横截面碳/碳复合结构的成品成本，或更大。 由于碳/碳价格的革命性降低而产生的公认成本/性能范式的变化将开放各种新的新商业市场，到目前为止，这些商业市场受到了使用成本限制，以使用较低的绩效热解石墨。 该研究包括设计和制造实验室规模的自动生产线，以及生产的碳/碳测试样品的过程优化运行和分析表征。 要证明的关键技术包括移动干碳纤维预成型的连续基质浸渍，它们可以通过处理设备的湿润部分，以及连续的高char屈服矩阵的在线内刚化。在单个碳化周期后，预期所得的“绿色”复合材料可开发成商业上可行的高密度碳/碳部分。 低成本碳/碳的机械和热性能要比该产品所取代的当前商业材料好很多倍。 碳/碳具有独特的高温热和机械性能。 一些大型美元价值市场将热切接受并应用商业价格的碳/碳组件包括热处理炉结构，制造钢制电弧炉电极，燃料电池组件，热交换器，热辐射器和十字架。
