Improving Interfacial Adhesion in Pla/wood Biocomposites

Comparison between accelerated thermo - hydro aged wood and naturally aged wood

The effects of aging in wood in term of physical, mechanical and chemical degradation has been studied first by Jiro Kohara [1] and more recently by Erhardt et al. [2-3] and Obataya [4]. It has been observed that similar degradation can be found in thermo-hydro (TH) treated wood [4]. The aim of this study is to compare the mechanical behavior of naturally aged and accelerate TH wood in the radi...

Strength of Wood Beams With End Splits

A method of analysis for determining crack propagation loads on wood beams with end splits is presented. The method is based on (1) linear elastic orthotropic fracture mechanics concepts, (2) theory of complex variables, and (3) least squares boundary value collocation (BVC). Using this method, the critical stress intensity factor, Kllc of Douglas-fir beams with end splits is determined to be 2...

Adhesion Mechanisms of Durable Wood Adhesive Bonds

This chapter presents and discusses the current state of the art regarding adhesion mechanisms in characterizing durable adhesive bonds for wood composites. Particular emphasis is placed on phenol-formaldehyde (PF) and polymeric methylene diphenyl diisocyanate (pMDI) adhesives. An overview of current adhesion mechanisms is presented with an emphasis on categorizing adhesion mechanisms relative ...
