Design and process optimization of reinforced natural fibre mat (NMT) composites by Pervaiz, Muhammad, M.Sc.F.,
|
Consumer awareness
and stringent environmental legislation has initiated a renewed interest in
using plant fibres as reinforcement in thermoplastics. The main objective of
this research project is to develop high performance sheet moulded natural
fibre thermoplastic composites by understanding and implementing new design
concepts of fibre morphology. We have determined important design parameters
such as critical fibre length, interfacial shear stress (ISS) and used them in
comprehensive modeling to predict composite strength. The model was validated
using experimental results. The study also indicated a significant improvement
of 15-20% in mechanical properties by using maleated
coupling agents and organo-silanes. A unique one-step
method of utilizing hybrid natural fibres in random orientation has enhanced
the impact energy absorbing behaviour of composite products by almost one
hundred percent compared to non-woven mat-reinforced thermoplastics.
Environmental performance of natural fibre composites compared to glass fibre
plastics in terms of energy consumption is also studied.
