Flexibility indicators of laminated, densified and carbon fiber reinforced wood

Abstract

In this report it was determined the modulus of elasticity, rupture, ductility and flexibility indices of Cryptomeria japonica wood. Solid and densified wood specimens were prepared, laminated with epoxy resin, and reinforced with carbon fiber. Static bending tests were performed in the radial and tangential directions with respect to the transverse direction of loading. The densification, laminating and reinforcement of C. japonica wood increases its modulus of elasticity and modulus of rupture. In contrast, these modifications decrease its ductility and flexibility indices. In addition, the parameters determined in the tangential direction are higher than those determined in the radial direction.
