Characterisation of cellular composites using synchrotron X-ray microtomography Background: Cellular materials are common. In nature they can be found in form of wood, bone and cork. Manmade cellular materials are usually honeycombs and foams. A great demand for bio-based, renewable and lightweight products has surfaced, in the wake of climate change and increasing oil prices. For example, the European project SustainComp (

Stiffness of aligned wood fiber composites: Effect of microstructure and phase properties

The effect of wood fiber anisotropy and their geometrical features on wood fiber composite stiffness is analyzed. An analytical model for an N-phase composite with orthotropic properties of constituents is developed and used. This model is a straightforward generalization of Hashin's concentric cylinder assembly model and Christensen's generalized self-consistent approach. It was found that most macro-properties are governed by only one property
