Its aim was to describe the release of BisGMA and TEGDMA monomers from composite core resin over three time periods. For this purpose, five Clearfil Photo Core resin samples were prepared and elution was measured using high performance liquid chromatography at 1, 7 and 28 days post-immersion in 75% ethanol. The findings confirmed good model fit to the data related to released monomer quantity.","PeriodicalId":20417,"journal":{"name":"Polymers and Polymer Composites","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78460440","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}

Different gas volume flows are set to vary the energy input during tape laying at 1 m/s. The tape preforms are characterized by means of thickness measurements, microsection analysis, peel-test, compression thermal analysis and flexural test to assess the degree of consolidation. Subsequently to ATL, tape preforms are processed in stamp forming at different pressure settings in a rapid-closing downstroke press. The resulting laminates are analyzed to assess the influence of tape preform consolidation and molding pressure. The results reveal a dependency between gas volume flow during automated tape laying and consolidation of the correspondent tape preforms. Laminate quality of specimen after stamp forming is independent to the tape preform consolidation according to the results of this investigation.","PeriodicalId":20417,"journal":{"name":"Polymers and Polymer Composites","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75130542","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 effective material properties of the shaft and disk are assumed to vary along their radius directions and determined via the Halpin–Tsai model together with the rule of mixture. Different non-uniform and uniform distributions of GPLs in the rotating assembly are taken into account. In accordance with the finite element (FE) method, the modelling and free vibration analysis of the nanocomposite shaft-disk rotor system is conducted. To verify the present analysis, both the theoretical and experimental methods are employed. A comprehensive parametric study on the effects of the graphene nanoplatelets (GPL) weight fraction, GPL distribution pattern, length-to-thickness ratio and length-to-width ratio of GPLs, shaft length, elastic support stiffness and rotating speed on the free vibration results are investigated, which gives effective ways to achieve improved mechanical performance of a rotating nanocomposite disk-shaft assembly.","PeriodicalId":20417,"journal":{"name":"Polymers and Polymer Composites","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76944136","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}
