Advanced materials and processes are required to meet the performance goals in the design of advanced turbofan engine, SiC/Ti composite is typically used in low pressure turbine shaft (LPTS). Firstly, establish the viability and effectiveness of composite cylinder assemblage (CCA) micro-mechanics model and representative volume element (RVE) micro-mechanics model which are utilized to calculate the mechanical parameter of continuous fiber reinforced metal matrix composite (CFRMMC), respectively. Results show that RVE model is more applicable to calculate continuous fiber reinforced LPTS. Secondly, parameters of mechanics performance calculated by RVE model are taken as input to build mechanics analysis model of fiber reinforced metal matrix composite shaft structure. The optimal solution will be got by design and analysis of CFRMMC shaft structure with 2 kinds of loads. Compared with deformation and stress of shaft structure with different material scheme, then an optimization scheme of SCS/Ti2AlNb composite of LPTS can be obtained.

A novel 3D printing route to fabricate continuous fiber reinforced metal matrix composite (CFRMMC) is proposed in this paper. It is distinguished from the 3D printing process of polymer matrix composite that utilizes the pressure inside the nozzle to combine the matrix with the fiber. This process combines the metallic matrix with the continuous fiber by utilizing the wetting and wicking performances of raw materials to form the compact internal structures and proper fiber-matrix interfaces. CF/Pb50Sn50 composites were printed with the Pb50Sn50 alloy wire and modified continuous carbon fiber. The mechanical properties of the composite specimens were studied, and the ultimate tensile strength reached 236.7 MPa, which was 7.1 times that of Pb50Sn50 alloy. The fracture and interfacial microstructure were investigated and analyzed. The relationships between mechanical properties and interfacial reactions were discussed. With the optimized process parameters, several composites parts were printed to demonstrate the advantages of low cost, short fabrication period and flexibility in fabrication of complex structures.
