In the
present study, traditional and hybrid composites were prepared
by Hand lay-up molding and investigated. The composites
constituents were unsaturated polyester resin as the matrix, 3%
and 6% volume fractions of carbon fibers as reinforcement and 3%
of Al2O3, Al, Cement and local Gypsum (calcium sulfate anhydrate
CaSO4) as filler particles. The investigated physical properties
were density, porosity while the mechanical properties were
tensile properties, bending modulus of elasticity. The
experimental results showed that increased volume fraction of
carbon fibers to (6%) led to increase in physical properties
(density, porosity. As for the mechanical properties, carbon
fiber composites and (3% carbon fibers/Al2O3)-contained hybrid
composites gave the higher tensile and fracture strength, carbon
fiber then gypsum composites gave the higher bending modulus. |
