Studi Kekuatan Tarik Serat Nonwoven Silikon Karbida

Abstract

-Tensile strength measurement has been done for silicon carbide nonwoven fiber that produced for polycarbosilane using electrospinning technique. Silicon carbide nonwoven fibers produced with the same process parameter (high voltage, tip to collector distance and feed rate solution). The curing process time varied at 1, 1.5 and 2 hour(s). The pyrolysis process took placed after the curing process for 1 hour. Tensile measurement for the nonwoven fiber has done by framed the sample and the pulling speed at 1 mm/s. The results showed the tensile strength of nonwoven fiber has a lower value compared to the woven silicon carbide fiber. Tensile strength of the fibers against the curing process time were 1.85 MPa, 8.98 MPa and 10.66 MPa, respectively. The fibers diameter value against the curing process time were 6.13, 4.17 and 4.23 μm. These results showed the fibers toughness take the tensile load caused by the friction and adhesion inter-fibers, then the elasticity of fibers depend on the fibers diameter
