However, an even more significant increase in demand in automotive is foreseen if the cost price of carbon fiber could come down substantially. In 2012 the US Department of Energy set a target price level of 10 USD/kg to get carbon fiber into mainstream cars. These low-cost carbon fibers should possess a tenacity of at least 1.7 GPa with a corresponding elastic modulus of 170 GPa. Carbon fibers are currently predominantly based on polyacrylonitrile (PAN) precursor fibers, while pitch is used for some high-modulus fibers. The cost price of PAN-based carbon fibers is determined for at least 50% by the PAN precursor. Consequently, over the last decade huge R&D programs have been undertaken in search of cheaper and more sustainable precursors such as lignin and polyethylene. Despite major efforts no significant commercial successes have been obtained up to now in stark contrast with numerous claims in the scientific literature regarding so-called breakthrough technologies. Next to the recent revival in carbon fiber research another carbon allotrope, the carbon nanotube (CNT), has received huge attention as the ‘next generation’ reinforcing element for composites. Fibers and yarns have been made directly from CNTs or have been added into other high-performance fibers to boost their properties. However, also here despite major research efforts and numerous high impact publications the results obtained were at best interesting or doubtful with little commercial success.</p></div>","PeriodicalId":7186,"journal":{"name":"Advanced Industrial and Engineering Polymer Research","volume":"5 2","pages":"Pages 90-106"},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2542504822000100/pdfft?md5=2a8aee91ae15d71881b6cba9f4084bb3&pid=1-s2.0-S2542504822000100-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47088394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this research, the necking defect in an EFC process has been studied experimentally and the effects of macromolecular architecture such as long chain branching (LCB) on the extent of necking have been determined using image processing methodology. The methodology is based on the analysis of a sequence of image frames taken with the help of a commercial CCD camera over a specific target area of the EFC process. The image sequence is then analyzed using Matlab® based image processing toolbox wherein a customized algorithm is written and executed to determine the edges of the extruded molten polymeric film to quantify the necking defect. Alongwith the necking defect, particle tracking velocimetry (PTV) technique is also used in conjunction with the Matlab® software to determine the centerline and transverse velocity profiles in the extruded molten film.

We also aimed to explore the property changes caused by the larger specific surface area due to the size effect. Samples were prepared with a hydraulic press after internal mixing. In the case of ground tire rubber (GTR) filled mixtures, the tensile properties showed rubber-like characteristics: with a significant decrease in modulus, elongation at break remained high, and tensile strength slightly decreased. The fracture surfaces of the samples were analyzed by scanning electron microscopy (SEM), wherein the case of materials made with uGTR showed better adhesion between the phases. In order to investigate the interfacial adhesion between the GTR and LDPE, we performed dynamic mechanical thermal analysis (DMTA). The glass transition peak of the uGTR shifted to a higher temperature and the storage modulus was higher than in the case of samples containing fGTR. Finally, we determined the Shore D hardness of the materials, which decreased with increasing GTR content, but hardness was greater in the case of uGTR samples. The better mechanical properties of blends containing uGTR were explained by better interfacial adhesion between the two phases due to the significantly higher specific surface area compared to fGTR.</p></div>","PeriodicalId":7186,"journal":{"name":"Advanced Industrial and Engineering Polymer Research","volume":"5 1","pages":"Pages 12-17"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.aiepr.2021.07.001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43666483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
