This study investigates the vibration and viscoelastic characteristics of composites reinforced with argan nut shell (ANS) particles, with mass fractions of 10, 20 and 30%. A multi-criteria analysis was used to select the appropriate thermoplastic matrix for composite fabrication, considering criteria like stiffness, wettability, density and fatigue resistance. Viscoelastic properties were assessed by dynamic mechanical analysis (DMA), and the modal properties were identified using an experimental modal analysis. The results show that the incorporation of ANS improves composite stiffness, which is reflected in increased resonant frequencies and storage modulus, but decreases damping capacities compared to the virgin matrix.

摘要

This study investigates the vibration and viscoelastic characteristics of composites reinforced with argan nut shell (ANS) particles, with mass fractions of 10, 20 and 30%. A multi-criteria analysis was used to select the appropriate thermoplastic matrix for composite fabrication, considering criteria like stiffness, wettability, density and fatigue resistance. Viscoelastic properties were assessed by dynamic mechanical analysis (DMA), and the modal properties were identified using an experimental modal analysis. The results show that the incorporation of ANS improves composite stiffness, which is reflected in increased resonant frequencies and storage modulus, but decreases damping capacities compared to the virgin matrix.
