Fiber reinforces sintered composition materials

摘要

The dynamics of composition powder material extrusion vs. technological parameters is studied The extrusion parameters for porous performs of copper fibres and Cu-Mo composite one are optimized. It is shown that orientation of fibers is possible when the latter are distributed non-consentrately in powder matrix as well as when ld. The physical-mechanical properties of composition powder materials are studied. A practically non-porous structure is formed when λ=4-6. In this case the fibers strength is realized in full extent.
