Mechanical and Electrical Characterization of Glass Fiber-Epoxy Composites with Date Pit Powder
Maher Nadher Abdullah Abstract: This research investigated the influence of filling date pits powder (DP) on the physical and mechanical characteristics of glass fiber-reinforced epoxy composites (EG) to form glass fiber reinforced epoxy resin filled with date pit powder (EGDP). Composite materials were produced with different DP ratios: 5%, 10%, 15%, 20%, and 25% wt. Measured results indicated a progressive enhancement in mechanical properties, comprising tensile, bending, impact resistance, shore D hardness and physical properties, consisting of dielectric constant, dielectric loss and A.C. electrical conductivity, together with water absorption relatively, when DP≤15%. This enhancement was ascribed to the homogeneous filler distribution and improved interface bonding between the filler, fibers and polymer matrix. On the other hand, when the filler ratio DP ≥ 20%, a reduction in performance was detected as a result of the creation of voids and agglomerates, leading to a decrease in the mechanical and physical characteristics. As a result, 15% was regarded as the best concentration ratio that led to attaining the best compromise between mechanical and physical enhancement and structural stability of the composite.
