Nowadays, replacing petroleum-based materials with renewable resources is a major concern in terms of both economical and environmental points of view. In good agreement with this emergent concept of sustainable development, this work deals with the study of innovative green polyamides (DAPA) based on rapeseed oil-dimer fatty acid reinforced with cellulose fibres (CF). Mechanical properties of DAPA and its biocomposites were examined. Tensile tests were used to follow the effect of strain rate, temperature and filler content on the Young modulus and the yield stress. Tensile tests revealed that the Young modulus and the yield stress highly increased with increasing CF concentration. Halpin-Tsai and Eyring's micro-mechanical models were found to successfully predict the Young modulus and the yield stress respectively, of DAPA and DAPA/Cellulose biocomposites. These results clearly highlighted the attractive properties of DAPA-based biocomposites and demonstrated that these materials are good alternatives to conventional composites.
