Injection moulded bamboo charcoal(BC) particles were used to reinforce Polylactic Acid (PLA) polymer
to enhance its mechanical properties. It was found that by increasing small amount of BC particles into
PLA would enhance its impact strength, tensile strength and modulus of elasticity. The formation of
mirror , mist and hackled zones of PLA/BC samples observed under fractographic images through an
optical microscopy has explained their energy absorption mechanism . To achieve better mechanical
properties of PLA/BC composites with the consideration of ease of manufacturing , it was found that the
optimal percentage of BC particles for PLA/BC composites is 7.5 wt%.
