The Crack Growth Behaviors in FRP Plates with a Surface Crack

摘要

In order to clarify the crack growth behaviors in the glass fiber reinforced plastic (GFRP) plates, the experimental investigations were performed with the aid of a AE system. The tension specimens made by three types of glass fiber cloths (Woven Roving, Glass Cloth and Chopped Strandmat) were monotonically loaded and the glowth of a surface crack were recorded by a video camera. It was cleared that the crack growth behavior of GFRP plates were particularly different in the types of fiber cloths and the volume fractions.
