Process development for Titanium Composite Cost Reduction and Manufacturing Maturity, TiCCRaMM

钛基复合材料（TMC），即钛合金基体中的碳化硅纤维，是一种新型材料，具有独特的强度和低重量的组合，在航空航天、空间和能源领域等一系列应用中具有吸引力。钛基复合材料降低成本和制造成熟度项目的目标是为TMC开发现有的生产技术，为这些行业的高价值供应链奠定基础。该提案汇集了一个由TMC专家SME TISICS（原始设备制造商Rolls-Royce和Messier Bugatti Dowty），SKYLON航天器开发SME反应发动机和供应链合作伙伴Bodycote HIP领导的财团。该项目旨在解决提高制造成熟度和可行的制造经济性的关键技术挑战;减少碳化硅纤维工艺步骤，开发可定制的净成形制造方法，新的低成本和/或可重复使用的模具材料，并提高原料转化率。目前需求量低、成熟度低以及制造方法分散在原始设备制造商和中小企业之间，使得该技术目前不经济;成功将为TMC带来世界领先的低成本集成能力，作为未来英国供应链的基础，以满足苛刻的应用、市场和环境，这些都是质量关键且不适合聚合物复合材料的。在航空航天领域，TMC可以减轻重量，从而减少燃料燃烧、排放和生命周期成本。同样，在其他部门也可以提高性能、可靠性和使用寿命。

Titanium matrix composites (TMC), silicon carbide fibre in a titanium alloy matrix, are novel materials with a unique combination of strength and low weight attractive in a range of applications e.g. aerospace, space and energy sectors. The objective of the TICCRAMM – Titanium Matrix Composite Cost Reduction and Manufacturing Maturity - project is to develop existing production technologies for TMC to lay the foundation for a high value supply chain into these sectors. The proposal brings together a consortium led by TMC specialist SME TISICS of OEMs Rolls-Royce and Messier Bugatti Dowty, SKYLON spacecraft development SME Reaction Engines and supply chain partner Bodycote HIP. The project aims to resolve key technological challenges for greater manufacturing maturity and viable manufacturing economics; reducing silicon carbide fibre process steps, developing customisable net shape manufacturing methods, new low cost and / or reusable tooling materials and improving feedstock conversion. Current low volume demand, low maturity and manufacturing methods dispersed between OEMs and SMEs make the technology uneconomic at present; success will lead to a world-leading, low-cost integrated capability for TMC as the foundation of a future UK supply chain for demanding applications, markets, and environments which are mass critical and unsuited to polymer composites. In aerospace TMC can reduce weight and thus fuel burn, emissions and life cycle costs. Similarly, improved performance, reliability and service life can be achieved in other sectors.
