Effect of time at temperature for natural fibres

The manufacture of natural fibre reinforced polymer matrix composites is generally assumed to be limited to temperatures not exceeding 200 degrees C. However, given the covalent bonding in the various constituents of natural fibres, they should retain properties to an extent dependent on the time at temperature. This study considers fibre mechanical properties after heating in air for various temperatures and times. (C) 2017 The Authors. Published by Elsevier Ltd.
