Thus, it is important to understand the long-term shear performance. Therefore, we proposed the tensile shear testing method to investigate the long-term shear performance of wood. This testing method is to apply stabilized axial load for a long-term and to be able to measure the shear deformation. In order to evaluate the method, the results were compared with results of JIS block shear test. As a result, the mean value of shear strength in the proposed method was 30% lower than the block shear test. The reason for the small results of the proposed method is that the specimen has two shear face and breaks at the weak side, and the shear face is affected by rotation due to the tensile deformation of the perpendicular to grain direction. Therefore, the coefficient of variation of 6.8% in the proposed method shows smaller than 11.1% in the block shear test. And the shear strength value of the proposed method was little bit higher than one of the four-point-bending type shear test methods, and all specimens were shown the shear failure. Based on these results, the proposed method was judged to be useful as a shear test method.","PeriodicalId":17390,"journal":{"name":"Journal of The Society of Materials Science, Japan","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135761433","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}

In order to make this technology applicable to general purpose, LDPE or LLDPE is suited as the base resin, and thin films should be produced by the inflation method. In this study, we attempted to realize a transparent moisture-absorbing film with LLDPE as the resin material and 50% nano-sized zeolite addition. However, the higher the zeolite content, the more difficult kneading and film-forming processes become. In fact, by using the blown film extrusion and cast film extrusion processes, it was impossible to form a film by tearing after extrusion when film processing was attempted by adding nano-sized zeolite with a surface modification treatment that produces high transparency. The results of our attempts to improve the problems from these results, it was found that a combination of a surface modifier that is highly effective in increasing the refractive index of the particles to increase their transparency and a modifier with excellent processability can be useful to facilitate kneading and molding. As a result, it was confirmed that resins containing 50 wt% surface-modified zeolite with such two surface modifiers could form 30 micrometer-thick films without dilution.","PeriodicalId":17390,"journal":{"name":"Journal of The Society of Materials Science, Japan","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135761436","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}
