Title : The effect of carbon whisker loading on carbon foam on physical and mechanical properties

Abstract :

Carbon foam is demanded in large quantities since it has certain attractive features like lightweight and high-temperature stability makes them versatile in many applications. Since the carbon foam from renewable resources gets a lot of attention, this study is a focus to fabricate a high strength carbon foam using natural resources such as sucrose and carbon whisker to produce good strength properties of carbon foam. The specimens were prepared via blowing method with varies loading of carbon whiskers of 0.1 wt%, 0.2 wt%, 0.3wt%, 0.4 wt%, 0.5 wt% and 0.6 wt% before mixing with sucrose and boric acid. Then, the materials are mixed uniformly with carbon whisker and boric acid for 2 hours. Next, foaming and setting of solid organic foam for 48 hours and dehydration for 16 hours. The carbonization in the inert atmosphere takes place for 2 hours constant temperature and the heating rate at 2°C/min until 900°C. The morphology, porosity, density and compression properties were analysed in this study. SEM analysis presented the distribution of carbon fibre on the wall structures and some debonding and holes were observed. Images of carbon fibre still bonded between walls surfaces and embedded on the wall structures were also observed. The bulk density result shows that the highest carbon whisker contains has a higher value reading which is 0.238 g/cm3 with 84.87% of porosity. The highest whisker carbon contains shows a good result in compressive strength which is 0.13 N/mm2 and it can be concluded as the best parameter among their carbon loading
