“…However, there are some results that show relatively high compressive strength for HDPE/wood flour 50 wt% of approximately 41 MPa, 18 which is significantly higher than the flexural strength (approximately 27 MPa) of the same composite and values for a similar composition (HDPE/sawdust 50 wt%), for which flexural strength was 22 MPa and tensile strength only 9 MPa. This is similar to composites with well-aligned reinforcement, where the compressive strength under loading in the reinforcement direction is usually lower than the tensile strength.…”

“…It has been well-known for a long time that MC affects not just the dimensions but also the physical and mechanical Fig. 1 A typical time-stress graph of a longitudinal compression followed by a fixation for 5 min, based on Báder and Németh (2018a) properties of wood (Huang et al 2006;Hernández et al 2014). Bauschinger published this fact in Munich in 1883, and many researchers dealt with this topic later, because of its practical and theoretical importance (Tiemann 1907;Vorreiter 1949;Kollmann 1951;Niemz and Sonderegger 2017).…”

Since the properties of wood significantly change with its moisture content, it is important to know the effect of different moisture conditions on wood. A brief summary is provided on this topic in the first part of this article. The compression along the wood grain is a modification resulting in better pliability. The moisture dependence of mechanical properties of longitudinally compressed wood is not known yet. For this purpose, the results in this article are considered as basic research results. Bending-and compression tests on beech specimens compressed longitudinally by 20% were carried out at different moisture contents. Changing moisture content has almost no significant effect on the modulus of rupture of wood that has been longitudinally compressed, compared to the sensitivity to changes in moisture content of untreated wood. However, the effect of moisture content on the change of bending modulus of elasticity, compressive strength parallel to the grain and bendability coefficient diverges significantly. As a result of these changes, there is a great difference in the pliability with different moisture contents of treated wood. For the best pliability during bending, the moisture content of longitudinally compressed wood must be close to its fiber saturation point.Publisher's Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

“…Good agreement was found between measured parameters and theoretical predictions. Munoz-Escalona et al [48] impregnated six low density tropical hardwoods with vinyl monomers and cross-linked them using a 60 Co source of radiation. The aim was to produce dense wood composites with properties equal to those of denser hardwoods.…”

The second part of a comprehensive review of the literature on wood published in the Journal of Materials Science since its inception in 1966 is presented. The topics reviewed include wood modification and surface treatment, the thermal stability of wood and resistance to fire, the physical properties of wood chars and wood-based carbon materials, and the structure-related properties of wood-cement and wood-polymer composites. The papers reflect the wide range of techniques utilised to improve wood properties, the role of wood as a precursor for carbon-based materials and cellular ceramics and the application of wood as a composite reinforcement. JMS is in the vanguard of the latest developments in all these disciplines.
