摘      要：The purpose of this research is to know the mechanical characteristics of polymeric foam and polyurethane with fiberglass reinforcement. The focus of the observations on the average maximum compressive force, mean maximum stress and elastic modulus where the observed characteristics are obtained from static press test. Furthermore, tensile testing is performed to observe the mechanical characteristic of mean maximum force, mean maximum stress and elastic modulus. The polymer as a matrix is use 157 BQTN-EX with thermoset resin with fiberglass reinforcement. Tensile test specimens were made according to ASTM D638 standard and ASTM 1621-00 standard for static press test. Three variation of composition is A, B and C where fiberglass used 10%, catalyst 5%, resin 55% and polyurethane 30%. The test result showed that the test specimen on composition C value of characteristic compressive force average 22.838 kN, the mean maximum compressive stress average 19.128 MPa and average modulus of elasticity is 161.447 MPa. While on tensile test the variation of material composition with the same fiber was obtained on compositional test specimen C value of the mean gravity characteristics of the average maximum of 1.214 kN, the mean maximum tensile stress is 20.243 MPa and average modulus of elasticity is 803.634 MPa.
