A method of femtosecond laser multi-pulse grid-like point etching (MP-GPE) was used to prepare glass fiber reinforced plastics with superhydrophobic properties. This article investigates the influence trend single-pulse energy (5-35 μJ) and pulse number (20-100) on morphology surface concave holes, including depth width. Different combinations process parameters have a modulating effect size hole structure ablation plastics. At 25 μJ 60 numbers, holes increases maximum approximately 63 μm, width upper is 33 μm. Under these conditions, water contact angle 160.6° obtained, which consistent theoretical calculation results 161.6°. very promising for power industry use this material in low-temperature, drag-reducing environments.
