Introduction: The utilization of wood pulp fibres in composite materials has gained major interest during
the last years. One of the major motivations has been the potential of wood pulp fibres and
their nanofibrillated derivatives for increasing the mechanical properties of some materials.
However, in order to exploit the full potential of wood pulp fibres and cellulose nanofibrils
as reinforcement in hydrophilic and hydrophobic matrices, several characteristics of fibres
and their interactions with a given matrix need to be understood.
With the increasing capabilities of novel microscopy techniques and computerized image
analysis, structural analysis is moving forward from visual and subjective evaluations to
automatic quantification. In addition, several microscopy techniques for obtaining 2D and
3D images of a given composite material, including field-emission scanning electron
microscopy (FESEM) and X-ray micro-computed tomography (X-µCT), have evolved
considerably during the last years. X-µCT is a non-destructive method for obtaining the
three-dimensional structure of a physical material sample. It is well suited for structural
analysis of complex heterogeneous materials such as paper, biological materials and fibrous
composites (Samuelsen et al., 2001; Holmstad et al., 2005; Axelsson, 2008). In addition,
FESEM is a powerful technique for assessment of a variety of materials. One of the major
advantages of FESEM is its versatility and high-resolution power (Chinga-Carrasco et al.,
2011). Structures down to 1-2 nm can thus be visualized and quantified.
In this work we will focus on practical and complementary imaging and image analysis
techniques. We will also give a brief introduction to SEM, X-µCT and to 3D image analysis
methods, emphasizing topics that are relevant for characterisation of composite materials.
Selected case studies of wood pulp fibre-reinforced composite materials and their
corresponding microstructure-property relationships will be discussed.
