High-density composite panel based on wood fibres and leather shavings; Study of mechanical properties
Pages: 19 - 24
Marius C. Barbu,
The up-cycling of alleged residues from industrial production processes provides a sustainable way to raw material procurement. In this work high density fibreboards (HDF) were manufactured with different leather amounts by using spruce fibres, as well as vegetable and mineral tanned leather shavings (Wet White, Wet Blue). Subsequently, their mechanical and physical properties were analysed and compared with each other, as well as with those of wood fibreboards. To gain an insight into the
mechanical properties of the panels and their internal bond (IB), flexural modulus (E) and bending strength were tested. The results for the urea formaldehyde-bonded HDF boards show enhancement of the transverse IB with increasing Wet Blue leather content, whereas the other mechanical properties decline meanwhile. The results of this study underline the usefulness of integrating leather shavings to HDF and give an overview of their influence in wood fibre materials.
