Conclusions

The feasibility is demonstrated of substantially reducing volume changes during the sintering of high-porosity materials by the addition of fibers to a powder mixture. The mechanism of sintering of powder-fiber composites containing more than 25% of fibers is similar to the mechanism of sintering of pure fiber materials. The mechanical properties of permeable composite materials are determined by the fiber component, and their hydrodynamic characteristics by the powder component.
