This study proposes a self-healing system using multiple short microvascular channels in the through-thickness direction. First, the impregnation advantageofusing thischannelconfiguration isconfirmed through delamination infiltration tests. Next,thefeasibilityofthischannelconfigurationisevaluatedbytensiletestsandfour-pointbending tests.Doublecantileverbeamtestswerethenconductedtoconfirmitshealing function.Finally,this system is applied to composite stiffened panels and the healing performance is evaluated using compression testing following panel indentation. The healing system almost fully recovered the originalstrength,confirming itshigh potentialunderpracticalconditions.Additionally,theweight reduction potential of the self-healing system was discussed through a strength comparison of specimens with different thicknesses.","PeriodicalId":145108,"journal":{"name":"Journal of the Japan Society for Composite Materials","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132134964","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}

In addition, interfacial shear strengths were evaluated using the feature points of the measured load-displacement curve.It can beconcluded from the results that the higher the interfacial shear strength, the higher the macroscopic tensile strength.
