Therefore, monitoring the state of composites and setting up an appropriate manufacturing process are essential. With the sheet winding method, prepregs are wound around a mandrel with each prepreg having an edge formed at the seam. Two forms of prepreg edges can exist: one where the prepreg edge has a gap, and the other, where the prepreg edge overlaps. This research examined the effects of the forms of the prepreg edges on the cure-induced internal states using a fiber-optic-based method. In the case of the edge involving a gap, strain level peaks at the prepreg edges were observed throughout the curing process. Meanwhile, the sample containing an overlap presented no strain level peaks during cooling. According to the results, it would be preferable to have overlapping present at the prepreg edges.","PeriodicalId":7291,"journal":{"name":"Advanced Composite Materials","volume":"141 1","pages":"674 - 685"},"PeriodicalIF":2.9,"publicationDate":"2022-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59703269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study demonstrates a numerical prediction of the rolling tire noises considering tread composite material models in the coupled acoustic-structural finite element analysis. The viscoelastic master curves were developed for the frequency-dependent damping in the structural vibrations of the tire. It was numerically found that the tread composites with 230.4% and 1,428% larger storage (E’) and loss moduli (E”), respectively, resulted in 1.16–9.79% louder structure-borne noises. Moreover, the elastic modulus (E) of the tread composites was proportionally related to the tire noises, suggesting that reduced elastic and viscoelastic moduli are desired for low-noise tires. This study can contribute to thoroughly understanding how the composite material properties, particularly viscoelasticity, can be designed to control structural noise and vibration in next-generation structures such as autonomous electric vehicles and urban air mobility.","PeriodicalId":7291,"journal":{"name":"Advanced Composite Materials","volume":"32 1","pages":"501 - 518"},"PeriodicalIF":2.9,"publicationDate":"2022-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42935920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effective material properties of FG-CNTs are changed through the thickness direction based on five diverse distributions of CNTs. All of the effective material properties of the nanobeam are temperature-dependent. Nonlocal strain gradient theory is applied to consider the size effect. A higher-order shear deformation beam theory is utilized to consider the shear impacts. Three kinds of relations are employed to study the effects of the hygro-thermo loading comprehensively on the frequency of the nanobeams. An analytical solution technique is utilized to solve the nonlocal governing equations achieved from Hamilton’s principle for several boundary conditions.

Furthermore, it was suggested that a mixture of calcium phosphate and alumina was formed at a sintering temperature of 1550 °C.

First, these models’ accuracy was verified by comparison with an elastic modulus measured for injection molded dumbbell specimens of CFRPA6. Although there was a slight difference between the elastic moduli estimated from the N–H models and the M–T model, the difference was discussed in terms of model properties. Next, estimation errors caused by assuming carbon fiber (CF) as isotropic were calculated under several conditions. The maximum error occurred in the condition that the tensile direction was perpendicular to the fiber axis. Despite CF had large anisotropy, it was approximately 10% for both models. We infer that the small error was caused by a specific stress field.","PeriodicalId":7291,"journal":{"name":"Advanced Composite Materials","volume":"31 1","pages":"564 - 582"},"PeriodicalIF":2.9,"publicationDate":"2022-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46481000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
