Abstract
Carbon dust (CD) is an industrial waste generated during machining process of carbon fibre reinforced polymer composite industries. The common practice disposing carbon dust was into landfill and recycling process. The recycling or reused carbon dust as filler still at the earlier stages due to the uncertainity in reclaimation process and to control the distribution of the carbon dust loading in thermoset under different parameters polymer processing. It has been reported that this carbon dust has demonstrated the possibility to use as filler to replace raw material especially virgin carbon fibre. This research demonstrate the fabrication of polymer composite using reclaimed carbon dust and resin as the matrices. The number of sample using different ratio of carbon dust varied from 0% to 30% and fabricated using vacuum bagging and autoclave curing method. Different approach of curing method performed on test sample to study the impact of process toward quality of sample that impact mechanical properties of the sample. The mechanical properties was determined using Universal Testing Machine (UTM) according to ASTM D3039 and ASTM D6641. Non Distruction Test (NDT) were also performed on fabricate samples according to E494-95 to validate the strength properties under destructive testing. The correlation between the distribution of the CD and the mircostructure from fractography images of tensile strength was observed through scanning electron microscope (SEM) to understand the relevant failure factors with the strength properties and processing parameters. The final result shows that the increase of rCD content as a filler loading inside thermoset decrease the value of tensile strength but increase the value of compression strength. The observation using SEM shows that the increase of rCD cause more weak ashesion between resin and the matrix hence impact the mechanical properties of thermoset. During curing parameter control using Autoclave, the increase of pressure cause better inner quality of thermoset with less void content and porosity hence increase the tensile strength value. However, the compression strength does not shows significant impact upon increasing of curing pressure.
