Mechanical Behaviour of Polypropylene And Human Hair Fibres And Polypropylene Reinforced Polymeric Composites

Abstract

Bio fibres have recently become eye-catching to researchers, engineers and scientist as an alternative reinforcement for
FRP (fibre reinforced polymer) composite. Due to their low cost, fairly good mechanical properties, high aspect strength .Three to
four ton of human hair fibre wasted in India annually .These fibre pose an environmental challenge In order to find commercial
application the wasted human hair fibre mixed with polypropylene.
Polypropylene based composite are prepared using hair fibre obtained from human hair. Human hair fibres are mixed into
polypropylene (PP) at 3,5,10 and 15 % by wt. using two roll mills. The composite are compression moulded at specific time and
temperature. Polypropylene and hair fibre polymer reinforced composite have better flexural and impact strength than PP
(Polypropylene) and lower the tensile strength of polypropylene and hair fibre polymer reinforced composite than (PP)
polypropylene.
