Abstract
Based on the dispersion characters of organic modified attapulgite (OAT) short fibers in nature rubber (NR) matrix, this paper analyzed the effects, in terms of addition amount of OAT, processing technology of rubber compound and heat treatment, on mechanical properties and anisotropy of OAT/NR composites. Results indicated that mechanical properties were better when the OAT content is 50 phr and thin-passing is 20 times, meanwhile, the longitudinal and transversal tensile strength of OAT/NR composites were 17.01 0.5 Mpa and 14.18 0.5 Mpa respectively. The anisotropy is obvious. Also the tensile and tear broken section were studied by the scanning electron microscope (SEM) and the forming mechanism of OAT/NR anisotropy composites was discussed.
