Pushout and pullout testing on single fibers are the two primary methods for examining interfacial properties such as the coefficient of friction, residual stresses, interfacial strength or toughness, and the fiber roughness. In this study, single fiber pullout tests were performed on silicon carbide fibers (SCS-2) embedded in a barium borosilicate glass matrix. The samples were made by first passing the silicon carbide fibers through a flame and then sandwiching them between two pieces of glass. The sandwich was then heated in air for 75 min at 850°C under slight pressure. Relations between the length of the debond and the applied load (during progressive debonding) and between the embedded length and the applied load during pullout were determined from the pullout tests. The transparency of the glass allowed the propagation of the debond crack to be observed using an optical microscope. The roughness of the interface caused significant wearing during pullout.</div>","PeriodicalId":100298,"journal":{"name":"Composites Engineering","volume":"5 6","pages":"Pages 633-648"},"PeriodicalIF":0.0,"publicationDate":"1995-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0961-9526(95)00009-C","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90825719","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}

Contrary to the traditional approach which does not allow any relative displacement at the interface without fracture, this paper considers elastic deformation of the interphase zone between the matrix and the fiber by replacing the zone by an “equivalent elastic interface”. The elastic behavior of the equivalent elastic interface describes the local elastic rigidity and deformation of the interphase zone and can be quantified by a mechanics parameter called “shear stiffness coefficient” which is proportional to the ratio of the shear modulus to the local thickness of the interphase material. This paper also outlines an ultrasonic reflectivity modeling that can be used for the experimental measurement of the interfacial shear stiffness coefficient along the length of an embedded fiber. Further, an experimental method of measurement of the shear stiffness coefficient is presented and experimentally measured values are tabulated. The significance of the quantification of such a parameter is that the elastic property of the interface obtained can be used as a common basis among material scientists designing and developing the composite systems, and groups studying material behavior for life prediction. Also, the parameter can be used by production engineers to assure that the designed properties of the composite are being achieved, and by the end users to ensure that the designed and produced properties are being retained in use.</div>","PeriodicalId":100298,"journal":{"name":"Composites Engineering","volume":"5 6","pages":"Pages 697-711"},"PeriodicalIF":0.0,"publicationDate":"1995-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0961-9526(95)00010-K","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75189367","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 presented finite element model enables modelling of several important thick and thin ply stacking sequences like cross-plies, angle plies and quasi-isotropic laminates. Due to periodicity it suffices to model a representative volume element of the laminate. The boundaries of this unit cell represent prospective crack surfaces. In this way varying crack configurations and crack densities could be simulated. By application of periodic boundary conditions the stiffness tensors for laminates containing different crack configurations were calculated. The results are presented in the form of reduced engineering stiffness parameters as functions of matrix crack densities for a thick quasi-isotropic [(0°/90°/+45°/−45°)s]M glass/epoxy laminate, a thick [(0°/90°/+55°/−55°)s]M carbon/epoxy laminate and a thin (0°/+45°/−45°)s glass/epoxy laminate.

Samples aged in an oxidizing atmosphere have been tested in flexure at room temperature, and also by fibre “push-down” to investigate the interfacial properties. Tensile tests have been carried out from room temperature up to 1200°C on the BMAS material, and it was found that a steady degradation in strength occurred from 500 to 1100°C, with a small but significant increase up to 1200°C. Creep experiments have been performed on both the Pyrex and BMAS materials, it was found that Pyrex has a creeping matrix and elastic fibres below the matrix softening point, whereas the BMAS composite showed creep in both components, though at long times the creep rate was shown to be fibre controlled. A simple model for the development of strain with time is reported and used to obtain values for the creep rate of both the matrix and fibres.
