Interaction between Matrix Cracks in E-Glass/Epoxy Two-Dimensional MultiFiber Array Model Composites

The failure of composites has been the subject of intense research for many years. Although there are several composite failure mechanisms (e.g., fiber fracture, matrix cracking, delamination, and fiber-matrix debonding), the interphase region between the fiber and the matrix has been a critical fac...

Description
Summary:The failure of composites has been the subject of intense research for many years. Although there are several composite failure mechanisms (e.g., fiber fracture, matrix cracking, delamination, and fiber-matrix debonding), the interphase region between the fiber and the matrix has been a critical factor in all of these failure modes. This observation has fueled sustained and continuous research focus during the past 40 years on fiber-matrix interface strength. Although significant information has been obtained about the interphase region and its impact on composite failure, experimental micromechanics research to assess the influence of this parameter on the initiation and propagation of the different composite failure modes is a recent endeavor. In this communication, fragmentation data are presented for two-dimensional (2D) multi-fiber-array composites containing E-glass fibers that fracture with associated fiber-matrix debonding and matrix crack formation.
