Flexural, compressive and thermal characterization of hybrid composite materials

Abstract

In this research, investigate the effect of weight fraction (1%, 2%, 3%, 4%) industrial waste (silica gel particles) as fillers with 3% carbon fiber in unsaturated polyester resins on some properties such as flexural strength, flexural modulus, compressive strength, and thermal conductivity. Specimens composite was conducted by using the hand lay-up method and tested according to ASTM standards. The average particle size of the silica gel was 136.4 µm. Analyzed of the mechanical and physical properties that examined using SPSS with Tukey test and One Way ANOVA to know effect weight fraction of (carbon fiber/silica gel particle) on those properties, where statistical significance was set at P ≤ 0.05. From results, it is observed that the addition of silica gel particles up to 4% with 3% carbon fiber as strengthening materials to unsaturated polyester resins, leads to increase values the flexural strength, flexural modulus, compressive strength (293.00 ± 4.000 MPa), (5.4300 ± .04560 GPa), (124.67 ± 5.033 MPa) respectively, while the values of thermal conductivity decrease with addition 4% silica gel to (.0300 ± .02000 W/m.K°) compare with specimen unsaturated polyester (.3367 ±.03215 W/m.K°). The results of (SPSS) showed that the values (P) calculated from One Way ANOVA for flexural strength, flexural modulus, compressive strength, and thermal conductivity were (0.02, 0.001, 0.0001 and 0.04) respectively, less than (0.05) this indicates that the filler material has a clear effect on those properties that have been examined.In this research, investigate the effect of weight fraction (1%, 2%, 3%, 4%) industrial waste (silica gel particles) as fillers with 3% carbon fiber in unsaturated polyester resins on some properties such as flexural strength, flexural modulus, compressive strength, and thermal conductivity.
