摘要： The characteristics of two different kinds of lignocellulosic materials (vegetable fillers) with two morphologies as Argania nut-shells (ANS) particles and Coir Fibers (CF) were used as reinforcement for phenolic resin (Bakelite) in this work, and the composite are studied as a function of filler types, shape, content (10, 20, and 30% wt. percent) and manufacturing loading force (1500 and 3000 LBs). Compression molding was used to create the composites, which were then evaluated using Scanning electronic microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), bending, dynamic-mechanical-thermal and rheological studies. The morphology of broken samples demonstrates that both fillers are well dispersed and distributed. When fillers are added to the matrix, the flexural characteristics improve, and the optimal values are attained in the case of Argania nut-shells. The results showed that the kind and shape of the fillers had a direct influence on the dynamic mechanical characteristics of the composites due to the reinforcement's modulus augmentation. It was noticed that, the increment of manufacturing loading force decreased the mechanical and dynamical properties of composites. The optimum properties obtained indicate that the composites can only be manufactured at low manufacturing loading force (1500 LBs).
