Abstract
Mechanical properties and dimensional stability of wood
fibre plastic composites containing different commercial
coupling agents (PP-g-MAH) was studied. Polypropylene and
two types of wood fibres, particle board chips and cutter
chips from thermal treated wood were used in the
composites. The grade of the coupling agent has an effect
on the achieved mechanical properties of the composites.
The effects were similar for both types of fibres used.
The 3 w-% addition of the coupling agents improves more
the impact strength properties than the 2 w-% addition.
The wood-fibre plastic composites proved to be
dimensionally stable. The same coupling agent that
increased the mechanical properties of the composite, had
also a positive effect on the dimensional stability of
the composite. The strength properties of the composite
materials are improved when the interaction between the
polymer and wood fibres are improved. The improvement of
the interaction increases also the dimensional stability.
