Mechanical Characterisation Of Sawdust And Chipwood-Filled Epoxy Composite

Natural fibre are increasingly being used as reinforcement in commercial thermoset due to their low cost and renewable nature. In this research the composite of epoxy with sawdust and chip wood untreated wood fibre content 14% by weight as a filled were studied and waste wood obtained from the timbe...
