“…Moreover, the amount of defect within the grains increased with large grain size. Therefore, the hardness of specimens having large particles was lower than that of the small ones [6][7][8][9]. The figures also show that yield stress and compression strength increased with low particle size [10].…”

Al 2 O 3 is widely used as the reinforcing additive in the metal matrix composites. The influence of Al 2 O 3 particle size on the density, hardness, microstructure, yield stress, compression strength, and elongation of the sintered Al-Al 2 O 3 composites were investigated. In the present study, 10 wt% of Al 2 O 3 powder with three different particle sizes (3, 12 and 48 µm) were used in the production of the samples. Powder metallurgy technique was utilized to obtain more homogeneous Al 2 O 3 distribution across the composites. The samples were cold pressed at 440 MPa, and sintered at 550 • C for 45 min. Results showed that the relative density of the composite was initially increased with decreasing particle size. However, it was decreased with further particle size reduction. It was also pointed out that the mechanical properties of the specimens were increased with decreasing particle size. The grain size and particle distribution homogeneity was decreased with raising the particle size.

“…This is due to presences of large content of reinforcements (SiC particles) at the surface of composite which accelerates the pits growing into the metal. In addition, that the pits initiation sites tend to possibility of occurring galvanic corrosion on the interface between the hard ceramic particles and soft matrix alloy [7]. …”

Abstract-This paper aims to study the corrosion resistance of metal matrix composite of an aluminum alloy (Al 6061) reinforced by SiC particles with 10wt% and 20wt%. Composite materials were prepared by stir casting using vortex technique. Corrosion behavior of aluminum matrix composite in sea water (3.5% NaCl solution) was examined using potentiostatically polarization measurements. The corrosion rate was calculated by Tafel equation and from the achieved polarization results. It was found that adding of SiC particles to the aluminum alloy matrix increases the corrosion rate. It was shown that the corrosion resistance decreases with increasing of SiC particles as compared of base alloy. Index Terms-Aluminum matrix composite, stir casting, electrochemical corrosion.

“…Polymer matrix when reinforced with fibers results in some single-phase materials that are better representative of certain properties, which could not be attained by two materials. Apart from advantages in terms of strength and stiffness, properties such as corrosion resistance [1], wear resistance [2] and temperature resistance [3], make them suitable for aerospace industries, marine industries, automobile & wind turbine blades [4].…”

Abstract. In this work the effect of notch position on the flexural properties of neat epoxy GFRP laminates were assessed. Three different set of samples consisting three specimens were prepared. First batch of samples comprised of specimen without any stress raisers, while other two batches consisted samples with 1mm deep and 1 mm wide groove. Further, the notched samples were tested at two different orientations, making the notch to appear on the top (compressive face) and bottom (tensile face) of the specimens. Testing was conducted at the loading rate of 1mm/min according to ASTM D790-17 standard. Test results revealed that when notch was present on the loading side (compressive face), the ultimate strength increased, as the stress raiser compensated the compressive deformation (fiber crushing) and allowed the laminate to go for higher deformation. Whereas the same notch when appeared on tensile face, strength of material decreased. Average ultimate strength of samples without notch was 234.7 MPa while the same for samples with notch on compressive and tensile face were 240.7 MPa and 194.5 MPa respectively. Average flexure modulus of the samples with notch on the compressive and tensile side was 13.27 GPa and 11.90 GPa respectively as compared to 14.44 GPa of sample without notch.
