Abstract

Enhancing the physical characteristics of high-performance materials is largely dependent on the reinforcement of polymers by microparticles. The physical behavior of polyester composites containing coconut and walnut shell microparticles was thus investigated in order to create an engineering material for industrial use. Most researchers investigated the flammability test of fiber bio-composites only. There is a possibility that two particular polymers embedded in a thermoset polymer matrix could provide the lowest burning rate in length per unit min. Microparticles from walnut and coconut shells were mixed completely with polyester resin in separate batches. In this study, a new set of polymer composites with varying weight percentages of CSµP/WSµP (1:1) (2.5, 5.0, 7.5, 10.0, 12.5, and 15.0 wt%) and epoxy resin (LY 556) as a PMC material are used. At room temperature, epoxy resin (LY 556) and hardener (HY951) are mixed 10:1. Physical attributes including dimensional stability, density, and moisture content are examined. The enhanced binding between the epoxy resin and the CSµP/WSµP, as well as the decreased void formation, are responsible for the maximum density of 15.450 g/cm³ that the CSµP/WSµP (1:1) particulate-reinforced epoxy composites display. According to the results, these composites’ dimensional stability is at its best when the particle level is 2.5 weight percent. It is used in the door frames, windows and partitions of the kitchen and bathroom areas.

Keywords: Epoxy-based composite, physical characteristics, dimension stability, coconut and walnut shell micro particulate.
