Quantitative analysis based on atomic force microscopy characterization of interfacial properties between carbon fibers and epoxy resin subjected to hygrothermal and thermal treatments

It has been proved the interface between fibers and resin matrix suffers from severe service conditions, but it was rarely explored how to directly and quantitatively evaluate those negative effects. In this work, a novelly-designed quantitative analysis method was established via atomic force microscopy (AFM) based on shrinkage degree of resin matrix, and was further applied to assess the effects of hygrothermal and thermal treatment on the...
