Title : Effect of Carbonization Temperature on Physical and Mechanical Properties of Carbon Foam

Abstract :

Carbon foam is lightweight material that reveals many unique properties which is good thermal conductivity and high mechanical strength. This study is to generate carbon foam from sucrose and was derived from 10g of sucrose and 10 wt% of boric acid. The process was continued with the foaming process in the oven at 120oC for 48 hours. The solid organic foam was continued to dehydrating process at 250oC for 16 hours with rate of 2oC/min in a box furnace. The carbonization temperature was 600oC, 700oC, 800oC and 1000oC for 2 hours with the similar heating rate of 2oC/min. The purpose for carbonization process is to create a high quality structure and properties of carbon foam where the carbon content in the material increases while the precursor is carbonized. Finding shows the density and porosity value of 1000oC carbonization temperature is the higher which is 0.600 g/cm3 and 50.08% respectively. Scanning Electron Microscope (SEM) shows the surface structure of temperature 1000oC has more pores than other temperatures during the carbonization process. Energy Dispersive Spectroscopy (EDS) analysis shows oxygen content in the range of 2.08 to 11.73 wt% in the carbon foams prepared in the range of 600oC to 1000oC by the carbonization process. The highest carbonization temperature of 1000oC reveals the mechanical properties which is 2.307 N/mm2 as the highest compressive strength. It is concluding that the higher the carbonization temperature gives the higher compressive strength and the density due to the increase in the material structure of the pore
