Enhancement of mechanical properties of unsaturated polyester resin by mixing with carbon-kevlar hybrid fibers

Abstract EN

Mechanical properties of unsaturated polyester resin (SIROPOL 8340-PI) incorporated with carbon Kevlar hybrid fibers were calculated.

Impact strength, tensile strength, flexural strength, and hardness were studied for composite material reinforced with hybrid carbon - Kevlar fibers as a woven roving 0˚-45˚with density (1.77g / cm3) and (1.47g / cm3) respectively.

These fibers were mixed with unsaturated polyester resin in different reinforcement percentage (20 %, 40 %, 60 %) and the effect on the above mechanical properties were studied, where we see Improves in these mechanical properties after reinforcement by fibers and the value of mechanical properties will increase with increasing percentage of reinforcement.
