Analysis of Mechanical Properties of Low Density Polyethylene/Rice-Husk Composite using Micro Mathematical Model Equations.

Abstract

Low Density Polyethylene and Rice-Husk of 0.300µm particle size were melt-blended together by extrusion process and the mechanical properties of the composite were investigated using ASTM D638 test method with Instron testing machine of LK10K and model-3 type. Experimental results showed that tensile strength and percentage elongation of the composite exhibited a gradual decrease with increase in filler loading while tensile modulus and hardness showed gradual improvement with increase in filler loading. The correlative analysis of the mechanical properties of the composite was compared with the experimental results and the results from the micro mathematical model equations. The result showed that there is a distinct variation between the experiment results and results from micro mathematical model equations. The mechanical properties of the composite indicate that it may useful in some applications that require low strength, high stiffness and hardness.

Combined effect of thermoplastic and thermosetting adhesives on properties of particleboard with rice husk core

“…However, modifiers are still expensive and increase the cost of UF adhesive. Polyethylene matrix is extensively used in the production of lignocellulosic filled thermoplastic composites because it is high performance binder for lignocellulosics [11][12][13] . For this reason, LDPE could play an important role in the production of particleboard having a rice husk core.…”
