A study on the trans-crystallisation behaviour of flax fibre reinforced polypropylene composites and effect on mechanical properties

Abstract

The effect of flax fiber reinforcement on crystn. behavior of polypropylene (PP) was investigated using a hot-stage optical microscope. To follow the crystn. kinetics, cooling rate and crystn. temps. were varied. Flax fibers with different processing history e.g. green flax, Duralin flax, alkali and silane treated flax were used for investigation. The effect of fiber treatment on crystn. behavior was obsd. Finally the effect of trans-crystallinity on the interfacial shear strength in micro-composites was studied by fiber pull-out metho
