Short term stress–strain properties were investigated for natural rubber reinforced with short cellulose fibres at various fibre loads. Stress–strain measurements were also performed on natural rubber composites containing cellulose fibres, electron irradiated in the presence of butadiene or N ‐hydroxymethylacrylamide, where the latter monomer produced the greatest improvement in stress–strain properties. Chemiluminescence analysis indicated the existence of a surface layer on the fibres after irradiation treatments, and water absorption measurements showed a decrease in water uptake for composites containing irradiated fibres. The results demonstrate the improvement of mechanical properties with a reduced sensitivity to moisture.
