A Study of Surface Morphology and Flexural Strength of Hemp Fiber Reinforced Composite with Recycled High Density Polyethylene Matrix

Abstract:

Hemp fiber has recently captured a significant interest in the science and engineering community because of its high specific strength and stiffness with an environmentally friendly feature. This paper reports a systematic study relating a specific surface treatment on hemp fiber with respect to the flexural strengths of the treated hemp fiber reinforced recycled polymeric composites. The flexural strength, strain, and modulus of rupture of the composite were tested on a constant rate of extension testing machine following ASTM standards. Surface morphologies of fiber and fracture surfaces of the composites were also observed using the Scanning Electron Microscope (SEM) and Fourier Transfer Infrared Spectroscopy (FTIR) technique.
