Abstract: This paper investigated the effects of different jet flow time on the inter-laminar shear strength (ILSS) of glass fiber cloth reinforced polymer (GFRP) composites. The results indicate that with the increase of the jet flow ablating time, the quantity of carbonized glass fiber cloth laminate increases linearly. The ILSS of remained GFRP composites decrease a bit, which indicates that the carbonized laminates on the surface of composite have little influence on the ILSS of remained deep-layer GERP composites. However, fracture model of glass fiber turn from tough to brittle. The results provide important data to the application of glass fiber cloth reinforced composites in the jet flow conditions.
