Mechanical behavior of cellulignin based composites

A powder derivative of acid pre-hydrolysis processing of cellulosic wastes, known as cellulignin, was used as filler in resin matrix composites. The f lexural mechanical properties of cellulignin-polyester, epoxy or urea-forma ldehyde matrix composites was evaluated. The results obtained show that the urea-formaldehyde and epoxy based composites can be used as alternative ma terials for low cost and low strength applications. Their advantages over t he common wooden agglomerates or composites are presented and are based on the fact that cellulignin can be obtained virtually from any cellulosic was te.
