Abstract

Polypropylene is a thermo plastic, tensile properties of polypropylene are crucial in the real world applications as they determine structural integrity and durability. Epoxy is a thermosetting plastic finds applications in various fields like aerospace, automobile, food packing etc. A major concern is the disposal of epoxy composites after their service life, since most of the waste is sent to landfills, causing land pollution and soil infertility. In this experimental study, polypropylene composites (PPE) were fabricated with varying weight percentage (5%, 10%, 15%, and 20%) of recycled micro-epoxy particles. The composites performance was evaluated under tensile loading. The findings revealed a moderate improvement of 15% in the tensile modulus. The tensile strength was declined by 7.2% for 20% recycled epoxy proportionate and percentage elongation also decreased drastically about 52.5% with increasing epoxy particle content. The reuse of waste epoxy particles in the polypropylene matrix leads to sustainability and circular economy. The Fourier-Transform Infrared Spectroscopy (FTIR) test confirms the cross linking of the epoxy. Scanning Electron Microscopy (SEM) was employed to examine the micro structure of the composite and also to analyse the material failure behavior. The SEM images at fracture surface shows material fails due to both ductile and brittle fracture. The SEM results confirmed that the recycled micro-epoxy particles were uniformly dispersed in the Polypropylene matrix material.

Keywords: Tensile properties, Polypropylene, Recycled Epoxy, Micro-compounder injection molding, and SEM.
