Resumen:
A novel fibre treatment recently proposed in the literature was
optimised 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. Optimisation 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.
