The Improvement in Mechanical Properties of Coconut Shell Powder as Filter in HDPE Composites

Journal of Polymer Science & Applications is a scholarly peer-reviewed, academic journal that publishes original research articles undergoing peer review process with the help of experts in the field of Polymer Science.

Composites have been prepared using the coconut shell powder and high-density polyethylene (HDPE) as the components. Coconut shell powder was mixed with HDPE via compounding of coconut shell powder and HDPE of HDPE and Coconut shell powder. The resultant materials were cast in three outlines and dried which resulted in composites. Their mechanical properties have been studied in detail and compared with the conventional composite made from the coconut shell powder used as reinforcement and high-density polyethylene (HDPE) which was used as a matrix. The resulting material can be used in the applications of Aerospace and Automobile etc.

Composite materials were developed as a class of materials capable of advanced aerospace, electronics, structural, automotive and wear applications. This composite material used in our study was coconut shell powder and HDPE (High-Density Polyethylene). The advantage of the composite materials is their tailored mechanism which includes low density, high specific strength [1-4]. The top five coconut producing countries are Indonesia, Philippines, India, Brazil and Sri Lanka. The places in India include Gujarat, Maharashtra, Karnataka, Kerala, Tamil Nadu, Bihar, Andhra Pradesh, West Bengal, Orissa, and Assam. A coconut usually contains coconut water and core which is consumed and the remaining is left a shell as waste.

These shells contain Natural fibers which are eco-friendly, biodegradables that are eco-friendly, cheap and renewable to the environment. Chemical composition of coconut shell powder consists of Lignin (29.4%), Pentosans (27.7%), Cellulose (26.6%), Moisture (8%), Solvent Extracts (4.2%), Uronic Anhydrides (3.5%) and Ash (0.6%) [5-9]. HDPE works like a hardener; the only type of polyethylene produced was LDPE. A German scientist (Karl Ziegler) made the greatest contribution in producing high-density polyethylene. The mechanical properties change drastically over high-density polyethylene to low density polyethylene. In general, the degree of branching in polyethylene determines its mechanical properties.
