Fracture Mechanics of the Microbond and Pull-out Tests
The properties of the fiber/matrix interface in composites have an influence on their overall performance. Common methods for studying the interface are micromechanical tests that load a single fiber/matrix interface to failure. Two popular tests are the microbond test [1] and the single-fiber, pull-out test [2]. In a microbond test a droplet of matrix is sheared off the fiber by pulling the fi...
متن کاملA shear-lag model with a cohesive fibre–matrix interface for analysis of fibre pull-out
A shear-lag model with a cohesive fibre–matrix interface has been developed for the analysis of stress transfer between the fibre and the matrix in fibre-reinforced composites in this paper. A bilinear cohesive damage evolution law is used to describe the fibre–matrix interface behaviour. The governing equations for the interfacial shear stress and the axial stress in the fibre are derived. Acc...
متن کاملTheoretical model of piezoelectric fibre pull-out
A theoretical model of a single piezoelectric fibre pull-out is developed to study the interaction between fibre deformation, pull-out stress and corresponding electrical field. Computer simulation of the stress–displacement curve of the fibre pull-out process is presented. Numerical examples show that the piezoelectric fibre pull-out behaviour can be both described and affected by its electric...
متن کاملInfluence of Different Adhesive Systems on the Pull-out Bond Strength of Glass Fiber Posts
This in vitro study evaluated the tensile bond strength of glass fiber posts (Reforpost - Angelus-Brazil) cemented to root dentin with a resin cement (RelyX ARC - 3M/ESPE) associated with two different adhesive systems (Adper Single Bond - 3M/ESPE and Adper Scotchbond Multi Purpose (MP) Plus - 3M/ESPE), using the pull-out test. Twenty single-rooted human teeth with standardized root canals were...
متن کاملAnalysis of Bond Strength by Pull Out Test on Fiber Glass Posts Cemented in Different Lengths
BACKGROUND The aim of this study was to evaluate, by means of pull-out test, the bond strength of fiberglass posts when cemented with different lengths in endodontically treated teeth. MATERIALS AND METHODS Sixty single-rooted bovine roots were cut in the cementoenamel junction with 21 mm length. They were endodontically treated and randomly divided into three groups (n = 20). Group 1 - Prepa...
