Shear propertiesSandwich panelCore materialBalsa wood is an appropriate core material for structural sandwich applications due to its high strength- and stiffness-to-weight ratios. However, the mechanical properties vary considerably owing to the inherent scattering of natural wood materials. One approach...
The mechanical properties of plantation-grown balsa wood from Papua New Guinea (PNG) were determined according to American Society for Testing and Materials D143-09. Static bending, hardness, compression parallel and perpendicular to grain, and shear parallel to grain tests were performed on kiln-...
In the present study, the mechanical properties of balsa wood required for the continuum damage mechanics analysis are calculated using experimental, analytical, and numerical results. Extensive experiments are carried out that evaluate the tension, compression, and shear properties. Equivalent modulus has...
This article presents an experimental study into thermal softening and thermal recovery of the compression strength properties of structural balsa wood (Ochroma pyramidale). Balsa is a core material used in sandwich composite structures for applications where fire is an ever-present risk, such as ship...

Kasal, in Encyclopedia of Forest Sciences, 2004 Relationship between Mechanical Properties and Anatomical Structure of Wood Wood anatomical structure significantly affects the mechanical properties of wood and wood composites. Parameters such ...
The core was made of wood fibers in the form of three dimensional wavy structure of 10 mm thickness. After gluing all layers, thin sandwich panels were prepared. For all panels, basic properties such as: density, Young's modulus and bending strength were determined. The results show that ...

Based on the experimental results and observations, several analytical models are proposed to predict the quasi-static compressive strength of balsa wood under uniaxial loading conditions. Results also show that the initial failure stress is very sensitive to the rate of loading, and the degree of ...

Mechanical properties of transparent wood based on delignified basswood impregnated with epoxy (D-basswood/Epoxy) has also been reported [1]. D-basswood/Epoxy composites showed EL = 5.78 GPa and σL∗ = 42.7 MPa, which means higher modulus but lower strength compared with D-Balsa/PMMA at...
