The multiaxial behaviour comparison of virgin polypropylene and polypropylene reinforced with 30 % glass fibres

Abstract

This study is concentrated on the multiaxial behaviour comparison of pure polypropylene to polypropylene reinforced with 30 % of glass fibre (PP30GF), both materials were subjected to the drop-weight test. PP is a semi-crystalline thermoplastic polyolefinic polymer which has a good resistance to the impact load and is commonly used in the wide area of the plastics industry to production of many application. In this study PP samples and PP samples with 30 % glass fibres were injection moulded and subsequently subjected to the penetration test at various potential energies. The results were evaluated and discussed. The results show that reinforced PP has a better behaviour at the multiaxial stress in comparison to the virgin one. © 2018, North Atlantic University Union.
