Also, compare the shift in Natural Frequency that of a SYP-SP (Sweet Potato) bio-composite to a commercial SYP composite. Additionally, the motivation behind the study is to eventually provide biodegradable materials, as petroleum-based products being a finite resource and having more potential to harm the environment. The researcher obtained the Natural Frequencies by Experimental modal analysis using a cantilever beam vibration technique. The shift for the first three natural frequencies for damage induced SYP-SP composite was 10%, 8.6%, and 9.5% and for SYP-Commercial composite was 7.95%, 0.7%, and 0.9% respectively. The undamaged specimens of SYP-SP bio-composite and that of a commercial SYP composite showed behaviour almost on similar lines. Thus, stating the potential use of SYP-SP bio-composite for commercial applications like wood flooring, fencing, and other related applications.","PeriodicalId":14414,"journal":{"name":"International Wood Products Journal","volume":"11 1","pages":"166 - 172"},"PeriodicalIF":1.1,"publicationDate":"2020-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20426445.2020.1780383","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47283957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the average fibre length in the sapwood was higher than the heartwood, while the lumen diameter showed the reverse. Holocellulose, α-cellulose, lignin, extractives, and ash content of the sapwood was higher than the heartwood.

The test surfaces included 12 varieties of untreated and modified wooden surfaces. A total of 17 participants took part in the experiments, in which they compared 33 specimen pairs arising from various surface combinations. The results demonstrated the considerable differences in tactile warmth quality among wood surfaces. Surface coatings, such as oil and varnish, and thermal modification induced a change in the tactile warmth of wood. In pine and birch, a decrease in the tactile warmth of the surface was readily perceived after surface densification. The results provide some insights into how materials could be selected, based on their warmth quality, to improve the thermal comfort of living spaces and suggesting that this could be achieved by the extensive use of wood.","PeriodicalId":14414,"journal":{"name":"International Wood Products Journal","volume":"11 1","pages":"129 - 137"},"PeriodicalIF":1.1,"publicationDate":"2020-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20426445.2020.1746889","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41747110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We hypothesize that students studying the structure and protection of wood will show similar acceptance of VR systems. We developed X-ray micro-CT models to show the distribution of silica in the Australian marine borer resistant timber, satinay and copper in treated pine. Students taking a course in wood protection used a VR device to explore the distribution of silica in satinay and copper in pine. Students were surveyed to assess their views on the system as a learning tool. The results showed that students were very positive about the VR system, and they frequently commented that the system was better than traditional methods at aiding understanding of wood structure/protection.
