Experimental Investigation on the Behavior of Hollow GFRP Pipes Subjected to Transverse Impact

Article Preview

Abstract:

As oil & gas exploration and production is moving increasingly towards offshore and deeper water, and then the demand for lighter and stronger material for deep water structures is growing. Fibre reinforced plastic (FRP) is a potential alternate. However, such application has low tolerance for accidental impact loads. This paper presents an experimental investigation on the behaviour of hollow glass fibre reinforced plastic (GFRP) pipes subjected to transverse impact. Drop weight impact tests were adopted. The GFRP pipe specimens were simply supported at two ends. The variations of strain, deflection and impact force were recorded. Different failure modes were observed and the critical factors affecting the damage of GFRP pipes were discussed. Their structural performance under transverse impact was assessed.
