INVESTIGATION OF SOME MECHANICAL PROPERTIES FOR NATURAL (EGGSHELL) AND INDUSTRIAL (CALCIUM CARBONATE) MATERIAL / REINFORCED WITH GLASS FIBER WITH POLYMER COMPOSITE

Abstract

The purpose of this paper is to discuss the influence of adding eggshell and calcium carbonate powder reinforced with glass fibers and epoxy resin. Hand Lay-up method was utilized for the preparation of samples from epoxy resin as a matrix material with (6%weight fraction chopped glass fiber) and (2%,4%, 6% & 8% weight fraction eggshell, CaCO3 powder) as filler material. The tensile and impact properties are tested for the specimens containing calcium carbonate and eggshell powder reinforced with glass fiber and epoxy resins, also the result analyzed by (SPSS) to determine the specimens have best mechanical properties. The mean particle size analyzer of the eggshell powder and calcium carbonate powder were (12.6µm, 0.4-1µm) respectively. The results showed that the mean values of tensile test, modulus of elasticity, impact strength and fracture toughness (247.50,222.00MPa) (8.450,7.500 GPa) (8.150, 7. 500K.J/m2) (9.1675, 7.8345 MPa.m1/2) respectively increased with the addition (6% glass fiber+8%CaCO2, eggshell), while the mean values of the elongation percentage at break (%) decrease with the addition (6% glass fiber+8%CaCO2). The SPSS statistical shown the values was significantly increased whenever the value (Sig < 0.05).
