To address the issues of low efficiency, high consumables usage, and low accuracy in traditional BWC mechanical performance testing, a non-destructive testing method for BWC mechanical performance was proposed based on machine learning. First, the images of the cross-section and longitudinal sections of the BWCs were collected. Then, a UNet-based image-segmentation model was used to segment the bamboo, wood, and holes in the cross-section. Additionally, the image features, including texture, frequency, and spatial characteristics of the BWC were extracted using the gray-level co-occurrence matrix (GLCM), db wavelet, Fast Fourier Transform (FFT), and Gabor filtering. Finally, the results of image segmentation and feature extraction served as inputs, and the corresponding mechanical performance parameters as outputs to build the dataset that informs the artificial neural networks (ANNs) model predicting the mechanical properties of BWCs. The research results show that the accuracy, mean intersection-over-union (MIoU), and Kappa coefficient of the image segmentation model are 0.9586, 0.8242, and 0.9125, respectively. In predicting the elastic modulus (MOE) and static bending strength (MOR) of the BWC using ANNs, the coefficient of determination (R) values were found to be 0.85 and 0.89, respectively. Besides, the mean absolute percentage error (MAPE) of the ANNs was 11.6% and 7.4% for MOE and MOR, respectively.

However, its heartwood, which has a high resin content (RC), is limited in its applications. This is because the exudation of resin can cause issues such as unsightly appearance, degumming, or paint bubbling, posing a significant challenge to its use. Hence, the heartwood of radiata pine was taken as the research object, and the resin in wood removed and fixed by microwave-superheated steam (MS) treatment was studied. The moisture content (MC), RC, relative content of turpentine, and the anti-resin-exudation performance were determined; the changes in the morphology of resin in the resin canals, the Young's modulus of the latewood cell wall, and the chemical composition were analyzed. The findings show that MS can remove some of the pine resin in the wood, but not all. Microscopic observations confirmed that some resin remained in the resin canals of the MS treatment samples. In addition, the turpentine content decreased dramatically after MS treatment. For instance, the average turpentine content of latewood in samples after treatment at 120 °C was reduced to 9.7%, only 0.3% after treatment at 140 °C, and no turpentine was detected after treatment at 160 °C. This may explain why the wood after MS treatment showed good anti-resin-exudation, as the volatilization of turpentine would lead to the increase in softening point and thermal stability of resin. In addition, the Young's modulus of latewood cell wall increased with superheated steam (SS) treatment temperature. The resin was oxidized, dehydrogenated, and isomerized after MS treatment. These findings confirmed that MS treatment improves the anti-resin-exudation performance of radiata pine by increasing the softening point of residual resin and fixing it inside the wood. Through this strategy, the treated radiata pine heartwood shows greater potential for application.</p></div>","PeriodicalId":550,"journal":{"name":"European Journal of Wood and Wood Products","volume":"82 3","pages":"785 - 796"},"PeriodicalIF":2.4,"publicationDate":"2024-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139501304","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}

In addition to the mechanical performance, it is also key to investigate the fungal susceptibility and moisture dynamics of poplar, to gain insight into the service life of engineered poplar products. This paper therefore investigates the fungal decay resistance, as well as the moisture sorption properties of (thermally modified) hybrid poplar clones and Norway spruce. Fungal decay resistance was tested using the mini-block test. Moisture dynamics were evaluated using a floating test and dynamic vapor sorption (DVS). A higher fungal decay resistance and a significant decrease of moisture sorption was observed for thermally modified poplar. Our results show that the overall moisture properties of poplar and spruce are similar and that differences among the poplar clones are negligible, demonstrating the potential of poplar wood for engineered wood products.

Upon subjecting oriented strand board to heat, it undergoes combustion, resulting in the production of gas and char as the primary decomposition products. This char layer serves as a protective barrier, shielding the underlying material from further combustion. Additionally, increasing heat flux resulted in a higher heat release peak and a reduced time to ignition, indicating a significant influence of heat flow during fire initiation and promotion stages. Moreover, higher heat flux led to a shorter flame burning duration and accelerated the sample's burning rate. Increasing gas diffusivity through the char raises the peak heat release rate and shifts the plateau region upwards. Similarly, reducing char thickness boosts the peak heat release rate.
