All wood cellulose films from flow
Flow is a variable that has fundamental effect on solutions, dispersions and suspensions. Molecular and particle alignment is facile to be induced by flow but control of the exact organization is far from trivial. Shear is dominantly present in film processing and a key controllable for cellulose materials. We elucidate on flow of cellulose dispersions in and prospect the knowledge to continuous film formation process.

Recyclable Composites with Wood based Reinforcement
Effective composites properties inherently depend on a vast array of micromechanical phenomena. In this project we aim to gain insights into the relationship between the properties (e.g. mechanical and wetting) and microstructure of the virgin and modified wood-based fibers. We investigate the interfacial properties, dispersion, pretreatments and environmental effects to quantify the impact of these on the effective composite properties.

Multiscale modelling and testing of biocomposites for equestrian sports
With this project, we aim to manufacture biocomposite materials, perform mechanical tests on them and model their mechanical behaviour. In particular, we target biopolymers reinforced with cellulose fibres, the latter which is an important resource from the Swedish forest industry. Due to complex hierarchical heterogeneous micro-structure of these materials, multi-scale modelling approaches including computational homogenization on realistic micro-structural RVEs and orientation averaging will be followed. It is also intended to link advanced in-situ experimental testing (in microscopy under mechanical loading) of constituent and interface properties to numerical multiscale models for predicting the mechanical response and failure of the biocomposite under deformation. The end application of the research is sustainable weight reduction in equestrian sports (saddles, fences etc.), where we see biocomposites as a very interesting alternative.
