Self-lubricating composites belong to a class of materials that provide a thin layer of lubricant, known as tribofilm, when two surfaces rub against each other. Composite wear surfaces exhibit different chemistry, microstructure, and crystal structure compared to unreinforced solid lubricant metal matrix composites, thanks to the presence of solid lubricants. However, these lubricants, which offer extremely low friction and a long lifetime, do not respond appropriately to different environmental conditions. Therefore, strategies have been developed to construct novel aluminum-based self-lubricating hybrid composites that can adapt to various environmental conditions. This article explores the potential of solid lubricants as essential components in self-lubricating hybrid composites. The present review focuses on Al-based self-lubricating hybrid composites and highlights the types of solid lubricants used as reinforcing phases, processing methods, and the tribological behavior of the composites.","PeriodicalId":42952,"journal":{"name":"Composites-Mechanics Computations Applications","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136008074","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}

Dental implant systems are created with polyether ether ketone-reinforced carbon utilizing a random sequential algorithm (RSA) that is modelled in ANSYS to understand the impact of internal-hex and conical abutment types. The abutment screw is tightened (stage 1), relaxed (stage 2), retightened (stage 3), and then relaxed (stage 4) to determine the preload value and removal torque. Internal hexagonal abutment connections and CFR-PEEK composite materials have been shown to be exceptionally good at preventing screw loosening. It is discovered that a conical connection is a poor abutment for preventing screw loosening.","PeriodicalId":42952,"journal":{"name":"Composites-Mechanics Computations Applications","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135601209","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}

Free damped vibration tests for the cantilever beams with different symmetric stacking sequences are performed. Logarithmic decrement analysis is used to evaluate the effective amplitude-dependent loss factor of the samples. Inverse analysis is used to find the dynamic properties of single ply based on the laminated beam theory and the complex moduli approach. It is found that the loss factors of GFRP laminates almost linearly depend on the maximum strain amplitude. Maximum value of the loss factor of unidirectional ply is realized in the transverse direction to fibers and reaches ~0.023 for the strain amplitudes up to 0.1% in the frequency range 20-60 Hz.","PeriodicalId":42952,"journal":{"name":"Composites-Mechanics Computations Applications","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135800893","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}
