Resumen:
Polymeric materials prepared from natural raw
materials have gained increased significance because of
unsure petroleum supply in the future and concerns
about environmental problems. Natural products are
attractive because they present several advantages, such
as abundance and availability from renewable resources,
relatively low cost and the possibility of biodegradation
in some cases (Rowell, 1997).
The chemical modification of vegetal oils can result
in new monomers with multiple functional sites (Khot et
al, 2001). The linseed oil resin obtained in this work
was further reacted with styrene by means of free
radical polymerization and filled with pine wood flour.
The knowledge of the creep behavior of these new
materials is essential for evaluating their performance in
practical appliances.
This work investigates the creep performance of
wood flour-linseed oil based thermoset composites.
Specially, the filler content and testing temperature were
considered in the evaluation of creep performance of the
composites. The Bürgers model was used to predict the
viscoelastic behavior of the composites. The effect of
time after sample preparation (aging) on creep behavior
was also evaluated.
