Hemp fiber reinforced composites was prepared using high density polyethylene (HDPE). Hemp fiber is a cellulosic fiber. It is used as reinforcement in thermoplastic matrix composite requires knowledge of their morphology and structure. In this paper, mechanical properties of chemically treated fiber reinforced HDPE composites were investigated over range of fiber content (0-50 wt%). The hemp fiber was alkali treated with 1-10 wt% to remove waxes and non-cellulosic surface components and triethoxyvinyl silane treated with 0.5-3 wt% to improve a better fiber-matrix interface. Fiber/matrix adhesion was assured by the use of use of polyethylene-graft-maleic anhydride (PE-g-MA) as a compatibilizer. Scanning electron microscopy (SEM), Fourier transforms infrared spectroscopy (FTIR), Differential scanning calorimetry (DSC), X-Ray Diffraction (XRD) and tensile tests were carried out for hemp fibers high density polyethylene composite. Findings indicate that a 5 wt% NaOH treatment effectively improved the fiber-matrix interface resulting in improved mechanical properties. All 40 wt% alkali treated fiber reinforced HDPE composites displayed higher young’s modulus and lower elongation at break as compared to neat HDPE, compatibilization with PE-g-MA resulted in an increased young modulus of the composites as consequence of an improved fiber-matrix interfacial adhesion.

In-situ synthesis of high-density polyethylene (HDPE) reinforced groundnut shell particulate (GSP) composite with treated GSP within the range of 10-30 wt% at 10 wt% has been achieved. The adopted technique used in the production of the composite is melt mixing and compounding using two roll mills with a compression moulding machine. Properties such as hardness, tensile strength, impact energy and water absorption analysis were examined. The result revealed that addition of GSP increases the hardness value from 22.3 to 87 Hv. However, the tensile strength progressively decreased as the GSP increases in the HDPE. This trend arises due to the interaction between neighbouring reinforced particulate which appears to influence the matrix flow, thereby inducing embrittlement of the polymer matrix. It was also observed that water absorption rate steadily increased with an increase in the exposure time and the absorbed amount of water increases by increasing the wt% of the GSP. Analysing the obtained results, it was concluded that there were improvements in the hardness, tensile strength, impact energy and water absorption properties of the HDPE-GSP polymer composite when compared to unreinforced HDPE. On these premises, GSP was found as a promising reinforcement which can positively influence the HDPE properties of modern composites.
