Flying on wood and fabric: The tree species used for the construction of the Ansaldo A.1 Balilla biplane (1918)

Mauro Bernabei et al.

Summary: The Ansaldo A.1 Balilla biplane is a significant historical artifact that showcases the Italian aircraft industry's advancements in World War I. It is primarily made of wood and has a skillful construction using various tree species. It represents a crucial piece of historical and cultural heritage prior to the rise of synthetic materials in aircraft construction.

Comparing the suitability of domestic spruce, beech, and poplar wood for high-strength densified wood

Matthias Jakob et al.

Summary: Wood is an efficient material in terms of mechanics, but often falls behind metals and engineered composites in terms of absolute mechanical properties. Densification is a promising approach to improve the mechanical properties of wood. This study investigated the densification of spruce, beech, and poplar wood through a two-step process involving chemical treatment and hot pressing. The results showed that chemically treated and densified wood exhibited better dimensional stability and improved strength.

The strength and stiffness of oriented wood and cellulose-fibre materials: A review

Matthias Jakob et al.

Summary: This article provides a selective review of cellulose-based fibre materials with either unidirectional or close-to unidirectional orientation. It describes the structure and representative values of strength and modulus of elasticity in fibre direction for each type of material, and offers a concise comparison of mechanical performance between individual fibre and bulk materials.

Interpretation of Strengthening Mechanism of Densified Wood from Supramolecular Structures

Kunpeng Li et al.

Summary: In this study, densified wood was prepared by hot pressing after removing partial lignin and hemicellulose through alkaline solution cooking, which resulted in improved tensile strength and elastic modulus. The content of intermolecular H-bonds was found to be significantly positively correlated with the mechanical properties of densified wood.

Characterization of Microstructure, Chemical, and Physical Properties of Delignified and Densified Poplar Wood

Jiajun Wang et al.

Summary: The densification of wood through delignification processes resulted in cell collapse and micro-cracks near the wood surface, enhancing hydrogen bonding among fibers. Increasing alkali dosage led to decreased set recovery, while considerable compressive deformation fixation was achieved through post-densification hydrothermal treatment at 180 degrees Celsius. The results suggest that delignified densified wood can be easily manufactured and exhibits great potential as a sustainable material.

Mechanical properties of compressed wood

Siavash Namari et al.

Summary: This paper presents a comprehensive test programme and database of Compressed Wood (CW) materials, with over 720 material tests conducted. The results will help engineers utilize CW in developing new products and connections, with comparisons made to characteristic values of solid wood from literature. The densification of wood significantly improves strength and stiffness, contributing to the uptake of CW in the building and construction industry for environmental benefits.
