Acoustic emission generated from wood-polypropylene composites

Abstract
Acoustic emission generated from wood-polypropylene composites. The objective of the study was to assess the effect of wood particle size on the characteristic of acoustic emission generated from wood-polypropylene composites and on their tensile strength. The maximum event count, total event count, percentage of maximum force at the time of acoustic emission initiation and tensile strength were determined. It was found out that the filling of polypropylene with larger wood particles significantly increases the maximum event count, total event count and tensile strength, and decreases the percentage of maximum force.
