Abstract In this work, Epoxidized natural rubber/sawdust short fiber (ENR-50/
SD) composites at different fiber content (5, 10, 15 and 20 phr) and size (fine size
at 60–100 μm and coarse size at 10–20 mm) were prepared using two-roll mill
and electrical-hydraulic hot press machine respectively. Curing characteristics,
water uptake, tensile, morphological, physical, and thermal properties of the composites were investigated. Results indicated that the scorch time and cure time
became shorter whereas torque improved as SD content increase. Though the
decline of tensile strength and elongation at break values, modulus, hardness
and crosslinking density have shown enhancements with the increasing… More >
