Bending strength of black and composite agglomerates of cork

Abstract

The bending strength of black and composite agglomerates of cork is investigated. In the preparation of the agglomerates, the raw material used was black regranulate (BR) of cork. Specimens of black agglomerate (BA) with a different thickness were obtained. In the case of the composite agglomerate (CA), both the particle size of BR and the resin dosage were varied. The bending strength increased with the increase in the specimen thickness for BA and in the particle size and the resin dosage for CA. This later parameter, in particular, greatly influenced such a mechanical property of this agglomeration product of cork.
