| Abstract | ||
| In this research a functionally graded polymeric composites (FGPCs) were produced using centrifugal casting method . These composites were fabricated from unsaturated polyester resin as a matrix reinforced with silicon carbide particles (SiCp) of different particle size (75,106,150 µm) and ( 6vol%)bulk volume fraction, using (600 RPM) mold rotational speeds . The aim of the present research was to study the effect of (SiCp)particle size on local values of volume fraction ,hardness and Young modulus at specific points along the graded samples. Hardness was measured at these points then graded samples were cut to eight portions . Density , volume fraction were calculated, then standard homogenous samples of constant but different volume fractions were manufactured. Results show that local values of volume fraction, hardness and young modulus decreased in nearby positions of the center of rotation and increased in positions far away from the center of rotation. | ||
