Abstract

The composites material is considered to be any multiphase such that exhibits a significant proportion of the properties of both constituent phases such that a better combination of properties is realized. The purpose of investigation of strengthener variation in mechanical properties of metal matrix composite was developed is to investigate the mechanical properties of metal matrix composite reinforced different geometry size and shape of reinforcement. Aluminum was chosen as the matrix material and low carbon steel as the reinforcement in the form of continuous rod and woven rod. There also differences in the reinforcement diameter been used among the sample. Mould was made from low carbon steel along with the jig. The jig is used to arrange the reinforcement orderly during casting process. The composite is fabricated by using on of the pressureless metal infiltration process which is stir casting technique. The amount of matrix and reinforcement used is about 95 % and 5 % from the finish part respectively. The composites properties among each sample with different geometry shape and size are compared. To make a comparison, investigation of mechanical properties of composites which is tensile test and charpy impact test conducted under ASTM D3552 and E23 standard respectively. The Scanning Electron Microscope (SEM) machine also used to study the interphase between matrix and reinforcement. The result shows that, reinforcement with geometry of woven form have better mechanical properties compare to the other two specimens with continuous form of reinforcement.
