Polymer composites reinforced with natural fibers designed with the lowest possible environmental degradation is the major objective of several scientific researches, we focus on polymer composites with polyamide 6 (PA6) matrix, because they are very abundant materials of the family of common plastics, finding its primary application in several fields such as the automotive, building, furniture and packaging industries.The choice of a reinforcement preventing plant waste responds to the challenge of developing new polymeric materials with advanced physicochemical and thermal properties while respecting the ecosystem.Through this study, we aim to recover natural waste, optimize the properties of polyamide 6 and make it more biodegradable.The rate of reinforcement relative to PA6 varies from 5% to 20% by weight, the impact on the properties of PA 6 was evaluated by IR, DRX, DSC, ATG and pycnometry.
