Effects of Different Advanced Engineering Materials on Deformation Behaviour of Wood Structural Materials

Timucin Bardak


Wooden composites reinforced with advanced engineering materials are promising as building materials. The use of these materials has been increasing in recent years. It is important to understand the behaviour of their deformation under load for optimum design of composite materials. There is limited information about the deformation behaviour of wooden composites under different loads. In this study, strain and displacement distributions were measured for wood structural materials made with glass fibre, carbon fibre, oak (Quercus robur), and polyurethane resin. The digital image correlation method (DIC) was used for this purpose. Deformation behaviours were determined from the images recorded under specific loads in the bending test. There was an increase of 17.3% in bending strength of wood composites with the addition of glass fiber. The cracking process was visualized for different advanced engineering materials. The imagery clearly showed the development of the strain and displacement field. The deformation behaviours of reinforced and unreinforced wood composites were different. The strain distribution of wood composites significantly affected the strength properties.
