For advanced ceramics composites, affordable manufacturing is still the most essential shortcoming with respect to successful commercial use. This holds particularly for components made out of composites with complex hierarchical structure and high demands of mechanical performance and reliability at the same time., e.g. fibre-reinforced ceramic composites (FRCMCs) which have been developed to overcome the intrinsic brittleness and lack of reliability of monolithic ceramics. Their major advantages include higher temperature capability, lighter weight, better corrosion resistance and adequate damage tolerance. There is a wide spectrum of FRCMCs depending on the chemical composition of the matrix and reinforcement although at present only Cf-C/SiC composites produced by the silicon infiltration route have obtained commercial production level. However, fibre reinforced composites based on oxides (Oxide-Oxide FRCMC) would offer essential advantages with respect to long time stability in oxidizing atmospheres. Although in the past decades there has been a considerable interest in Oxide-Oxide FRCMC, there is at present almost no production concept which meet the requirements in view of cost and performance. Here, this proposal starts and focus on a new concept based on the integration of two reactive production routes for alumina employed at TUHH (reaction bonding sintering) and UFSC (biotemplated alumina by Al vapour infiltration) which will give advanced performance and low production costs at the same time . For this route, an advanced shaping based on CAD/CAM concept (rapid prototyping by LOM) can be integrated additionally favouring easy small scale manufacturing which is in general very typical for these materials.

对于先进的陶瓷复合材料，负担得起的制造仍然是最重要的缺点，就成功的商业用途。这尤其适用于由复合材料制成的具有复杂层次结构且同时具有高机械性能和可靠性要求的部件。例如纤维增强陶瓷复合材料（FRCMC），其已经被开发用于克服单片陶瓷的固有脆性和可靠性的缺乏。它们的主要优点包括更高的温度能力，更轻的重量，更好的耐腐蚀性和足够的损伤容限。尽管目前只有通过硅渗透路线生产的Cf-C/SiC复合材料获得了商业化生产水平，但根据基体和增强体的化学组成，FRCMC有很宽的范围。然而，基于氧化物的纤维增强复合材料（氧化物-氧化物FRCMC）将提供在氧化气氛中的长期稳定性方面的基本优点。尽管在过去的几十年里，人们对氧化物-氧化物FRCMC产生了相当大的兴趣，但目前几乎没有满足成本和性能要求的生产概念。在这里，该提案开始并专注于一个新的概念，该概念基于TUHH（反应结合烧结）和UFSC（Al蒸汽渗透生物模板氧化铝）采用的两种氧化铝反应生产路线的整合，这将同时提供先进的性能和低生产成本。对于该路线，可以集成基于CAD/CAM概念的先进成形（通过LOM的快速原型制作），另外有利于容易的小规模制造，这通常对于这些材料非常典型。
