Effects of Hot Pressing on Resistance of Compressed Oil Palm Wood to Subterranean Termite (Coptotermes gestroi Wasmann) Attack

open access: yesBioResources, 2013
Oil palm trunks are a by-product of oil palm plantations and provide raw material to the woodworking industries. However, their resistance against degradation by termites needs to be improved; this study investigated hot pressing as a chemical-free ...

Can Elastomers Combine Stiffness, Toughness and Fatigue Resistance?

open access: yesAdvanced Materials, EarlyView.
This review studies how the molecular and macroscopic architecture of elastomers influence their mechanical properties including: stiffness, stretchability, toughness, fatigue resistance, and damping behavior. By linking the structure to performance, it proposes design principles for advanced elastomeric systems that combine mechanical properties ...

Displacement fields of wood in tension based on image processing: Part 1. Tension parallel- and perpendicular- to grain and comparisons with isotropic behaviour

open access: yesSilva Fennica, 2000
Displacement fields for tensile loaded rubber and wood in parallel- and perpendicular-to-grain were obtained from digital image correlation. The results showed that the digital image correlation can reveal fine details of the nature of displacements ...

Sustainable and Multifunctional Natural Macromolecular Polymers for Aqueous Zn Metal Batteries

open access: yesAdvanced Materials, EarlyView.
We comprehensively review the structure‐function relationships and regulatory mechanism of natural macromolecular polymers in stabilizing zinc anodes at the microscopic and mesoscopic scales. The interactions among polymer structures, optimization strategies, and regulatory mechanisms are discussed systematically summarizing recent related research ...

Compression drying of energy wood

open access: yesFuel Processing Technology, 2014
Abstract This study investigated the compression drying of energy wood in the form of sawdust. The test was carried out on freshly-felled Scots pine ( Pinus sylvestris ), Norway spruce ( Picea abies ) and Downy birch ( Betula pubescens ) in Finland. The compression pressure (6–38 MPa) and time (0–60 s) were adjusted in the experiments; it was found ...

Flax Composites With Improved Interfacial Strength Through Microbially Induced Mineral Precipitation

open access: yesAdvanced Materials, EarlyView.
A bio‐inspired biomineralization strategy introduces an additional hierarchy to flax fiber composites. By controlling microbe‐mediated mineral particle deposition through tuned salt concentrations, stress transfer within the natural fiber composite is enhanced.

Experimental determination of the limiting flexibility of eucalyptus wood for axially compressed elements

open access: yesStructural Mechanics of Engineering Constructions and Buildings, 2020
Relevance. Wood is one of the most widely used building materials throughout history, and because of its physical-mechanical properties it mainly has been used in flexed and compressed elements.

Surface densification of acetylated wood

open access: yes, 2016
The mechanical properties of wood can be improved by compressing its porous structure between heated metal plates. By adjusting the process parameters it is possible to target the densification only in the surface region of wood where the property ...
