Mechanical properties of epoxy based hybrid composites reinforced by glass fibers and sic particles

الملخص EN

In the present study mechanical properties of pure epoxy and hybrid composites were studied.

Pure epoxy and hybrid composites were prepared by Hand lay-up molding and investigated.

The composites constituents were epoxy resin as the matrix, 4 % and 8% volume fractions of glass fibers as reinforcement and 4 % and 8 % of silicon carbide as filler particles.

The investigated 0Tmechanical properties were hardness0T, 0Ttensile properties (0Tultimate tensile strength (UTS), fracture strength0T), and 0Timpact properties 0T(0Timpact strength, 0Tfracture toughness0T).

0TThe experimental results showed that 0Tthe mechanical properties, Hybrid composite with (Epoxy + 8 %GF + 8 % SiC) has the maximum hardness of (82) shore D, Hybrid composites with (Epoxy + 8 %GF + 4 % SiC) has the maximum (UTS), fracture strength, impact strength (GRcR) & fracture toughness (KRcR) of (107) MPa, (108) MPa, (9900) J / mP 2 P, (27.

487) MPa.mP -1 / 2 respectively.
