Composite material from waste poly (ethylene terephthalate) reinforced with glass fiber and waste window glass filler

ABSTRACT This research is manufactured composite materials from waste poly (ethylene terephthalate) reinforced with glass fiber and filled with waste window glass powder for tile application. The composite samples were prepared by the melt-mixing method followed by compression molding. The mechanical, thermal, and physical properties are investigated. To do this Charpy impact and Rockwell hardness testing machines, DSC, and Thermogravimetric analysis instruments were used. For this, it was prepared eleven samples by varying the glass fiber weight percentage from 0 to 10, matrix weight percentage from 70 to 85, and glass powder filler weight percentage from 5 to 20. The maximum impact strength (5.11 J/cm2) is recorded at 10% weight of glass fiber, 85% weight of PET matrix, and 5% weight of window glass filler. The maximum Rockwell hardness (184.2HR) and the minimum water absorption (0.048%) are also recorded at 0 weight % of glass fiber, 80 weight % of poly(ethylene terephthalate), PET, matrix, and 20 weight% of window glass filler. It can be concluded that the impact strength increased with increased weight % of glass fiber and decreased with increased window glass filler. The Rockwell hardness increased, and the water absorption decreased with increased weight % of window glass filler. GRAPHICAL ABSTRACT
