Cellulose fiber and nano-fiber composites based on castor oil-polyurethane matrix

Abstract

Hybrid cellulose composites comprising woven hemp fabric interspersed with microcrystalline cellulose in a matrix of castor oil based polyurethane. The compsoites were derived from natural resources except for the diisocyanate required for chain extension and crosslinking, together with likely interfacial bonding with the cellulose components. The composites were characterised using scanning electron and optical microscopy, therrnogravimetry and infrared spectroscopy. Mechanical properties measured were creep, recovery and modulated force thermomechanical analysis. Multiplexed frequency was used to obtain activation energy for the glass transition. The composites were semi-flexible, with hiigh tensile strength and toughness, the main damping peak was centred on ambient temperature making the composites suitable for vibration damping application.
