The tensile fractured surfaces of the CB-filled SMR-L with and
without ALK at various curing systems were examined by using a
Zeiss Supra-35VP scanning electron microscope (SEM) to obtain
information regarding the filler dispersion, rubberefiller interac-tion and to detect the possible presence of micro-defects.
The fractured pieces were coated with a layer of gold to eliminate
electrostatic charge build-up during analysis.
