In this study, the cruciform test method was used to experimentally evaluate the interfacial tensile strength in pitch-based carbon fiber/matrix. The process of interfacial debonding between pitch-based carbon fiber/epoxy resin was successfully observed, and an interfacial tensile strength of 41.3 MPa was obtained.

Immediately subsequent to theinitiation ofthetests,splitting occurred along thedirection ofthefiberfrom the tip of a notch, and rapidly progressed for all investigated stress levels. Thereafter, the rate of development was almost constant after 3×104 cycles and the AE behavior also changed. These results indicate that the AE behavior is indicative ofthe splitting behavior.We discussed the AE behaviorbased on theexperimentalresultsforthesplitting behaviorand therelationship between theAE,and thefatiguedamagebehavioroftheunidirectionalCFRP laminatewasobtained.From this relationship,it is possible to predict the damage type,size,and quantitybycomprehensively evaluating thefrequencycharacteristics,and each parameter oftheAE waves.","PeriodicalId":145108,"journal":{"name":"Journal of the Japan Society for Composite Materials","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129228350","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}
