Acoustic and mechanical properties of polymer composites reinforced by pre-deformed palm fiber

Abstract EN

This research was carried out to study the mechanical properties and thermal and acoustic insulation properties of prepared polymer composite.

Petiole date palm fibers with the length (2-3mm) and with different volume fraction ratio (10, 20, 30 and 40 %) were used as filler in preparation of polymer composite.

The research imply study effect of pre- deformation for petiole date palm fiber by chosen compression loads (0, 2, 4 and 6 MPa) on the mechanical properties as well as on the thermal and acoustic insulation properties of prepared composites.

It was concluded that the pre-deformation to the fibers improves the thermal and acoustic insulation properties of prepared composite, as well as an increase in the tensile strength and hardness values with increasing compression load on the fibers.

The highest values of the tensile strength and hardness reach to (133MPa) and (106) respectively for the polymer composite filled with 40 % volume fraction of petiole date palm fibers which pre-deformed under compression load equal to 6 MPa.
