“…The results of the tensile stress at break σ test are shown in Figure 6(a), it is observed that the composite 2 whose ber is treated with NaOH has a higher tensile stress value than that of the composite 1, this can be explained by the effect of the treatment of the bers which improves the cohesion between the surface of the ber and the chains of the PVC matrix, which results a certain hardness of the material. Unlike composites 3 and 4, where a second polymer was added, which caused a weak morphological structure of the composite [21].…”

Date palm (Phoenix dactylefera L.) fibers, which are natural wastes, have been recovered and exploited in the synthesis of composite materials by mixing them with two different polymers: polyvinyl chloride (PVC) and polystyrene (PS). The four samples were characterized using infrared spectroscopy (FTIR), water absorption rate (W) measurements, thermal conductivity (λ), and mechanics (tensile stress and stretching at break) testing. The results proved that: (i) At 40°C, the composites absorption rate was higher than at the room temperature. While this rate was better for the composites with non-alkali-treated fibers; (ii) to obtain a thermally insulating composite, polystyrene polymer should be added to the matrix and the alkaline treatment of the used vegetable fibers should be required. (iii) Composites made of non-alkali treated fibers have a high stretching at break values while composites made of alkali-treated fibers have a high tensile stress value.
