The study investigates the suitability of paulownia wood as raw material for plywood production, both as pure paulownia plywood and in combination with poplar, and compares the results with those of pure poplar plywood. For this research, paulownia trees were harvested from a six-year-old plantation in Northern Italy. The logs were peeled to produce veneers, which were then used to manufacture plywood panels. Veneers were classified based on surface appearance according to the European standard EN 365:1995, with the 46% rated as Excellent and the remaining 54% assigned to Class I. Plywood panels were produced using poplar, paulownia, and a mix of both species in a 5-ply configuration. These panels were evaluated for appearance, mechanical performance, and bonding quality. Bending tests were conducted in both longitudinal and transverse directions to determine the modulus of elasticity and strength; density was also measured. Bonding quality was assessed through shear tests after pretreatment, considering intended applications in both interior dry environments and exterior covered environments. Overall, paulownia plywood exhibited more surface defects, such as cracks, bubbles, and areas with adhesive exudation, compared to mixed poplar-paulownia panels. Its density was also lower than that of poplar and mixed panels. From the mechanical perspective, paulownia plywood showed lower strength and stiffness compared to poplar and mixed panels, with the mixed panels performing similarly to or slightly below poplar. While paulownia wood can be used for plywood production, it is most effective when used as internal layers in mixed panels with poplar.</p></div>","PeriodicalId":550,"journal":{"name":"European Journal of Wood and Wood Products","volume":"83 4","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145167211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite their favourable physical and aesthetic properties, their relatively low density limits use to wood-chip production and minor interior applications. This study aimed to enhance the material properties of these species through thermo-mechanical densification. The effects of compression ratio, pressing time, and pressing temperature were evaluated on color change, set recovery (wet and dry), pull-off strength, and delamination. <i>Eucalyptus nitens</i> showed excellent color stability under all conditions (ΔE*ab < 5), while Tasmanian oak exhibited significant darkening at 175 °C (ΔE*ab 6.17–9.06). At 175 °C and 37% compression, <i>E. nitens</i> responded more strongly, achieving a mean wet-use set recovery of 0.0%, compared with 2.7% for Tasmanian oak. Both species showed significantly improved dimensional stability at 37% compression ratio compared to 25%. The highest <i>F</i>-values observed for <i>Eucalyptus nitens</i> and Tasmanian oak were 25.36 and 17.91, respectively. Increased compression also improved pull-off strength in both species, but in Tasmanian oak, extractive migration at 175 °C likely reduced coating adhesion. The densification process had minimal impact on bondability overall. However, a higher pressing temperature significantly reduced delamination in Tasmanian oak (<i>P</i>-value 0.031), while showing negligible effect in <i>Eucalyptus nitens</i>. The results suggest that both <i>Eucalyptus nitens</i> and Tasmanian oak species were stable following the densification process and would make the densified wood serviceable under conditions in which the EMC does not exceed 17% if unprotected.

This study focuses on guamuchil wood (<i>Pithecellobium dulce</i>), recognized for its rapid growth, high hardness, and adaptability to arid environments, as a candidate for transparent wood applications. Unlike traditional delignification, which can damage wood, the photooxidative method used here preserves its integrity by partially modifying the wood under milder conditions. Thus, this study explores the enhancement of guamuchil wood transparency through a photooxidative process, an approach not previously applied to this species. Visual analysis revealed a progressive increase in transparency of guamuchil wood with UV exposure, reaching maximum clarity at 10 h (GW10) due to extensive chromophore degradation. Exposure beyond this point led to undesirable yellowing due to excessive oxidation. SEM analyses revealed the photooxidative treatment of guamuchil wood-induced cell wall thinning, increased cell diameter, and enhanced structural order. EDS showed a reduction in carbon content from 44.16 to 42.14% and an increase in oxygen content from 55.84 to 57.86%, indicating partial degradation of lignin. FTIR analysis confirmed these oxidative changes, showing decreased aromatic lignin peaks and increased hydroxyl and carbonyl signals, with lignin content reduced from 27.5 to 21.9%. The water contact angle decreased from 62.4° to 12.2°, reflecting increased surface hydrophilicity due to lignin degradation and the exposure of hydroxyl groups. These changes contributed to a substantial improvement in optical transmittance, rising from ~ 6% in untreated wood (GW0) to 19% in GW10 at 7 mm thickness, achieved without polymer infiltration. This demonstrates the effectiveness of the photooxidative process in enhancing transparency through selective lignin degradation and surface modification. This study demonstrates a novel photooxidative process to enhance guamuchil wood transparency, achieving significant optical improvement without polymer infiltration. The process selectively degrades lignin, offering a sustainable alternative to glass in construction with reduced environmental impact.</p></div>","PeriodicalId":550,"journal":{"name":"European Journal of Wood and Wood Products","volume":"83 4","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145166608","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analysis of flame patterns, temperature profiles, the mass loss rate and charring degree showed that cracks had a significant effect on the combustion behavior of wood. The mass loss rate (MLR) was higher for wood with radial cracks compared to wood without cracks. By introducing the concept of charring volume and assessing the effect of cracks based on charring length and depth, it can be seen that cracks have the greatest effect on the area directly exposed to the flame. The effect of cracks increases dramatically when the angle reaches 30°. Cracks affect combustion through two main mechanisms: firstly, external heating accelerates the airflow at the crack, creating an entrainment effect that increases the oxygen content in the combustion zone; secondly, the accelerated airflow enhances thermal convection.

Investigating its structural integrity when subjected to sudden impact loading is essential for advancing efforts in standardisation, development, maintenance, repair, and the preservation of its historically significant design characteristics. This study presents a comprehensive analysis of the dynamic structural response of a cura baglama subjected to controlled drop-test scenarios. A reverse engineering methodology, coupled with three-dimensional explicit dynamic analysis, was employed to examine the instrument’s behaviour under impact loading. The study evaluated the effects of seven distinct impact positions, simulating a drop from a fixed height of 1000 mm. The simulation results provided critical insights into the instrument’s impact response by visualising deformation patterns and equivalent stress distributions across its structure. Regions susceptible to damage were identified by comparing the computed equivalent (von Mises) stress with the material’s yield strength, which served as the threshold for irreversible damage. This approach enabled the determination of the critical drop height corresponding to structural failure in each scenario. The findings indicate that, although all scenarios were simulated at a fixed drop height of 1000 mm, Impact Scenario 5 exhibited the lowest calculated threshold for damage initiation, with a critical drop height estimated at 172 mm based on the material yield criterion. These structural impact response analyses offer valuable guidance for instrument designers, facilitating the development of cura baglama models with enhanced strength. While the findings are specific to the analysed instrument model, the methodological approach can be generalised to similar studies.
