Direct observation of microstructural fracture dynamics in carbon fiber reinforced plastics via in situ transmission electron microscopy
Source abstract
Abstract
Abstract The tensile deformation process of carbon fiber reinforced plastics (CFRPs) was in situ observed by high-resolution transmission electron microscopy (TEM). CFRPs were prepared with sizing and unsizing treatment on the fiber surfaces. The microstructural evolution of crack propagation along fiber/resin interfaces and inside resin matrices was examined. Fine resin fragments remained on the fiber surfaces after fracture. From the differences in the shape of the residual resin fragments between the two types of CFRPs, the influence of the sizing treatment on fracture was quantitatively evaluated. We demonstrated a new method on the basis of in situ TEM to evaluate the microstructural fracture dynamics and the influence of the sizing treatment on fracture.
