Effect of heat treatment on structure and mechanical properties of basalt fibers and its application for fabrication Cu based composite

Abstract This paper firstly presents an experimental investigation of the effects heat treatment temperatures and atmosphere on tensile strength structure basalt fibers. The results show that fibers after in air (200–600 °C) have characteristics amorphous state due to oxidation Fe 2+ into 3+ . On contrary, vacuum induces crystallization reason is cations can act as network modifiers participate enhance glass network. Furthermore, single fiber decreases with increase temperature. However, about 3 times treatment. this foundation, were used for fabrication copper matrix composites by spark plasma sintering (SPS) hot press (HPS) first time. exhibit reinforced prepared SPS 276 MPa, which are higher than HPS (192 MPa) fast heating rate short holding
