Influence Factors of the Compression Performance of CFRP Sheet Confined GFRP Short Pipe
Compression performance of pultruded GFRP (Glass Fiber Reinforced Plastics) can be improved by confined CFRP (Carbon Fiber Reinforced Plastics) sheet, but it was affected by some factors. Two groups GFRP short pipe specimens of different outer diameter (104mm and 76mm) were axial compressed. The failure modes of longitudinal splitting and compressive strength failure for the GFRP pipes and those confined by CFRP sheet respectively were comparatively analyzed. Analysis on the influence to the compressive performance of GFRP short pipes confined by CFRP sheet was made from mechanical and geometrical parameters of the CFRP and GFRP in numerical methods. The laws of improvement of compression performance of CFRP sheet confined GFRP short pipe were recognized.
