Stadying mechanical properties for polyethylene composites rein for by fish shell particles

Abstract

In this research we use both High Density Polyethylene (HDPE), and LowDensity Polyethylene (LDPE)were used as matrix to the composite material and fish shell particles were used as a reinforced filler, Plunger injection molding method were used to prepare samples which have different filler percentage as below:-1. Pure High Density Polyethylene (HDPE).2. Pure Low Density Polyethylene (LDPE).3. High Density Polyethylene (HDPE) reinforced with fish shell particles in thefollowing percentage (30, 40 and 50%).4. Low Density Polyethylene (LDPE) reinforced with fish shell particles in the following percentage (30, 40 and 50%).In this research some of the mechanical properties (Modulus of elasticity, Impact strength, Hardness, and Creep rate). The research results showed that the values of (Modulus of elasticity, Hardness) will increase with the increase of the filler percentage for both types of polyethylene used in this research, in the other hand thevalues for impact strength and the values of Creep rate of the all samples used in this research will be decreeing with the increase of the filler percentage.
