Electrical and Mechanical Performance of Hybrid and Non-hybrid Composites

Abstract

A B S T R A C TT his paper investigated the moisture absorption, mechanical behavior and the dielectric performance of hybrid and non-hybrid polymeric composites. Hand lay-up technique was used for processing carbon; glass reinforced polyester resin composites (non-hybrid) and carbon-glass/polyester hybrid composites with various fiber configurations. The maximum resistance of water absorption was obtained for the hybrid composites with combinations [2C-2G], where the water absorption ratio reached to 1%. In addition, the maximum tensile, flexural strengths and ILSS of t his combination were 123 MPa, 1397 MPa, and 22.35 MPa, respectively. This is due to the higher tensile strength of polyester matrix and good adhesion between the glass and carbon fabrics with the polyester matrix. The dielectric constant of nonhybrid composite with codes [C] is higher than non-hybrid composite with codes [G] and dielectric constant for all hybrid composites lies between non -hybrid composites.

Mode I fracture toughness of Carbon/glass hybrid comopsite

“…The manual hand layup technique was developed for manufacturing the non-hybrid and hybrid composites as a form of four layers. The details about the used technique and properties of the reinforcement and polyester resin are reported in previous publications [22][23][24]. The designation and stacking configuration of hybrid and non-hybrid composites are listed in Table 1 and Figure 1.…”

Effect of Water Absorption on the Tensile Characteristics of Natural/ Synthetic Fabrics Reinforced Hybrid Composites

“…Sanjay et al [7] the water absorption of laminate [G/G/B/G/B/G/B/G/G] was slightly exceeded from that obtained for laminate configuration with glass only. Carbon-E-glass/polyester hybrid composites, prepared by hand lay-up at several stacking sequences, showed the maximum moisture ratio reached to 3% at immersion time 264 hour for the combination [G/G/G/G] [8]. Also, Jesthi et al [9] used the same fibers (carbon and glass) reinforced polyester composites at various stacking sequences to evaluate the tensile strength after immersed into the seawater for 90 days.…”
