This paper describes the formation of carbon fibres from various precursors. Currently, the most widely used pre-cursor is polyacrylonitrile. This is due to the fact that the obtained fibre has very good strength parameters. In opposition to the non-organic source, a renewable material is presented, which is lignin. This review highlights the advantages of using this ecological precursor and presents the general properties of the obtained carbon fibre.","PeriodicalId":129081,"journal":{"name":"Insight - Material Science","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131457866","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 main purpose of this study was to address a new method in judgement of presence of ball in the volleyball field in the shortest possible time by manipulation of lines surrounded the field and the ball layer’s structure. A carbon semi- conducting fabric layer designed ball was thrown to the printed circuit board (PCB), which have replaced the surrounded field lines. The ball was thrown in six different angles of 15, 30, 45, 60, 75, and 90 degrees and with 20 and 40 m.s-1 speed. As soon as the semiconducting ball hits the PCB lines, the LED, which embedded under the PCB, turns on and announce the presence of the ball in the field. In 20 m.s-1 speed, the PCB detected 97.1% of ball presence in the field per 1500 trials six angles. Almost similar, in 40 m.s-1 speed, the accuracy of PCB in hit detection was 97.6% per 1500 trails. Additionally, regardless of ball speed, the more perpendicular the ball hit the PCB line, the accurate detection was made. The smart line judgment system could be a reliable, efficient, and affordable technology that provide referees with an accurate decision and athletes with a faster game flow. ","PeriodicalId":129081,"journal":{"name":"Insight - Material Science","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129985215","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}

Various crack propagation mechanisms, such as longitudinal splitting and shear-cracking, have been shown as possible strand failure mechanisms by themselves in strand, but this may not be true in stressed strand in piles that has been embrittled by Hydrogen and without pre-cracking (Cracks initiating from stress concentrations naturally rather than with notching). Concentration measurements were performed to determine the level of Hydrogen involved in the embrittlement.Results indicate that the fracture mechanism differs from shear cracking or longitudinal splitting alone as previously shown, but is a multi-step process of crack propagation starting perpendicular to stress, followed by variations of inter-lamellae longitudinal splitting at brittle region of lamellae and shear cracking at breaks in the lamellae. This process results in the crack following a “staircase” progression, and finally leading to ductile overload once cross-section has been significantly reduced. This fracture mechanism was also shown to be valid whether the strand was stressed by bending or mult-axially by stressing through a duct.","PeriodicalId":129081,"journal":{"name":"Insight - Material Science","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124225077","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}
