Resumen:
The aim of this work is to evaluate the effect of the fibers alkali treatment on the injection processing. Woven jute preforms were used to prepare the composites using the vacuum infusion technique. The fibers were treated with NaOH (5 wt%) for 24 h at room temperature. Single filament tests showed that the treatment was detrimental for the mechanical properties of the fibers. The injection times increased in the treated jute preforms as a consequence of the increase in the exposed area and the flow resistance. The preform permeability decreased, also, in the tubular structure collapse of the fibers, which could reduce the capillary pressure. Flexural and impact properties of the treated jute composites decreased mainly in the lower mechanical properties of the fibers.
