Resumen:
A novel fibre treatment recently proposed in the literature was optimized in the case of
woven jute fabric/vinylester laminates to obtain the best tensile properties. It consists on
an alkali treatment superimposed to biaxial tensile stress. Optimization was performed
by changing the treatment time. The novel fibre treatment was compared with
traditional chemical methods. Tensile properties exhibited a maximum with the
treatment time at 4 h due to the less efficient period of time and to the excessive fibre
damage for times shorter and longer than 4 h, respectively. All composites with fibres
treated with alkali under stress exhibited improved tensile strength in comparison with
the composites with untreated fibres or with fibres treated with traditional methods due
to the better interfacial properties and the structural changes of the fibres promoted by
the novel treatment. Stiffness values were only higher for the composite with fibres
treated with alkali under stress for 4 h, probably in correspondence with a maximum in
the stiffness of the individual fibres.
