Subject:
manufacturing; particleboards; wood
Abstract:
... As a response to increased costs and a shortage in wood supply it is a current approach to reduce the amount of material in the manufacturing process of particleboard (PB). However, the production of lightweight PB by simply reducing density results in decreased panel properties. Thus, investigations to re-engineer the panel’s core layer are required in order to achieve density-reduced panels whic ...

Abstract:
... This paper presents an analysis of 3-dimensional engineered structural panels (3DESP) made from wood-fiber-based laminated paper composites. Since the existing models for calculating the mechanical behavior of core configurations within sandwich panels are very complex, a new simplified orthogonal model (SOM) using an equivalent element has been developed. This model considers both linear and nonl ...
