Cylindrical samples were prepared with 0.1-0.5% by weight of SWCNTs and MWCNTs nanoparticles. The samples were tested for friction coefficient and wear rate using a pin on disk. Moreover, the mechanical properties were evaluated by measuring the density and hardness of the samples. The study found that the mechanical and tribological properties of HDPE composites were significantly improved. The best tribological properties were observed in the HDPE nanocomposite sample with 0.5 wt. % SWCNTs and 0.2 wt. % MWCNTs, resulting in a reduced friction coefficient and wear rate.","PeriodicalId":212154,"journal":{"name":"Journal of the Egyptian Society of Tribology","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123528588","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}

The present work investigates the ESC generated from the contact-separation and sliding of the composites of rayon and polyester (PET) strings blended by carbon fibers (CF) on wool fibers. The present experimental work showed that the values of ESC generated at 100 % rayon were relatively low. Sliding of rayon/PET on wool recorded higher ESC values than that observed for contact-separation. When rayon/PET was blended by CF, drastic drop in ESC was observed from the contact-separation and sliding of strings on wool. It seems that the the presence of CF conducts the charge from one surface to the other causing significan drop in the resultant ESC generated on the two surfaces. It can be concluded that blending rayon/PET by CF drastically reduced ESC so that the proposed textile became environmentally safe, where the effect of CF was significant.","PeriodicalId":212154,"journal":{"name":"Journal of the Egyptian Society of Tribology","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121915232","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 the present work, the ESC generated from the contact-separation and sliding of cotton and polyester (PET) strings blended by carbon fibers on wool fibers is measured. The experiments revealed that ESC generated on the surface of cotton/PET from the contact-separation with wool showed relatively higher negative values that increased with increasing PET content. While, the positive sign of ESC generated on the wool surface remarkably increased with increasing PET content. It was observed that ESC generated on the surface of wool from the sliding on cotton/PET displayed remarkable increase of positive values that may be attributed to the ranking of the cotton, PET and wool in the triboelectric series. It can be concluded that addition of carbon fibers (CF) drastically decreased ESC and consequently the proposed strings will be environmentally safe materials. The drastic decrease of ESC compared to that observed in strings free of CF is attributed to the easy charge transfer offered by CF.","PeriodicalId":212154,"journal":{"name":"Journal of the Egyptian Society of Tribology","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132152966","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}

This phenomenon is known as the triboelectric effect. The triboelectric series was developed in order to determine the likelihood of charge transfer when two materials come into contact with one another. This study aims to investigate the effect of calcium carbonate content in sedimentary rocks close to the city of Minia on the charge generated on the surface of the rock upon contact with another surface such as Kapton and polymethyl methacrylate (PMMA). The two materials were selected because Kapton is close to the bottom of the series, while PMMA is close to the top. It was found that a higher calcium carbonate content in a rock made it more likely to obtain a negative charge, thus lowering its position in the triboelectric series. Some rocks which are low in calcium carbonate with a few calcium carbonate-rich pockets on their surface induce a low charge on the surface they touch under a high contact force, due to the easy-to-break calcium carbonate pockets depositing calcium carbonate particles with an opposite charge on the other surface.","PeriodicalId":212154,"journal":{"name":"Journal of the Egyptian Society of Tribology","volume":"184 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133435161","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}
