Carbon fiber chemistry
WebThe carbon fibers (Zoltek, St. Louis, MO, USA) used are Chopped Carbon Microfibers (CCMF), with df = 7.2 μm diameter, 3 mm and 6 mm length, 416.7 and 833.3 aspect ratios, and Milled Carbon Microfibers (MCMF), with df = 7.2 μm diameter, length of 150 μm and 200 μm, and 20.8 and 27.8 aspect ratios, as shown in Figure 1 a. WebCarbon fibers were synthesized using a low-cost, economical method. Fresh rubber wood fibers ( Hevea brasiliensis) were burned using a furnace in an inert condition at 350 to 450 oC for 2-4 hours, and after that the fibers were ground at 18000 rpm for 20 to 40 seconds.
