Abstract

Carbon fiber is widely used in engineering applications. As existing assistive device is heavy, expensive and non-recyclable, reclaimed carbon fiber reinforced polylactic acid composite with different weight percentage of ratio is fabricated by using internal mixer and extruder. The effect of reclaimed carbon fiber and physico-mechanical properties of composite were studied. In this research, the weight ratio of reclaimed carbon fiber is 0 wt.%, 10 wt.%, 20 wt.% and 30 wt.%. After that, the composite panels are cut to desired dimension of specimen according to ASTM standard. Then, morphology properties and mechanical properties are studied. From the data collected, it concluded that the density, tensile properties and flexural properties of the composite are increasing along with the increasing fiber loading. Carbon, oxygen, sulfur and zirconium element are present in the reclaimed carbon powder when the pretreatment of reclaimed carbon powder are investigated by using energy dispersive x-ray spectrometer. The dispersed of carbon fiber and fiber pullout are observed by using scanning electron microscope. For the composition with 30 wt.%, the carbon fiber is fully dispersive and melt around the PLA because there is no porosity detected in the micrograph image. Therefore, it has the highest tensile strength if compare with other composition.
