Özet

Hybrid composites are material types obtained by combining two different composite structures. This study focused on investigating the mechanical properties of a hybrid composite material produced in a circular shape with aluminum sheath and metal matrix composite core (Al-Ceramic mixture). Mechanical properties were determined by compression, bending, and hardness tests. Ceramic reinforcement improves the basic mechanical properties of metal matrix composites (MMC). However, some features such as strain ability are adversely affected. It was aimed to improve such properties by producing MMC material with sheath. Al7075 was used as the sheath material and Al2124-B4 C MMC material was used as the core material in this hybrid material. Composite rods were produced by extruding the billets prepared by the PIT (powder in tube) method. With this method, the core material in powder form was compressed into Al tube materials. In the core material, three different ratios of B4 C were used as 5, 10, and 15% by volume fraction. The extrusion process was carried out at 500°C degrees and with an extrusion rate of R=14. According to the test results, the strain ability, which decreased with the B4 C reinforcement, improved in materials produced with sheath.
