Analysis of curved composite pipe under internal presure effect
The aim of this research is to study the behavior of composite curve pipi under internal pressure. Two groups of materials are used to manufacturing curved pipe. The first group is including woven roving (Mat) carbon composite pipes /epoxy composite and the second group is involving woven roving (Mat) fiber glass composite pipes /epoxy composite with 50% volume fraction. The experimental work included manufacturing pipe specimens by vacuum bag technique. Pipe specimens were having 100mm inner diameter, 450 mm length of curvature center line of curve pipe with (43 degree) and wall thickness is (4 and 3 mm). The test rig was designed and performed to study the effect of internal pressure on the composite pipes. Also, the tensile test of the samples was done. The analytical expression solution has been accomplished to determine the strain, stress, for hoop and longitudinal direction. It is evident that the hoop stress for woven roving carbon composite pipe was great significantly from the woven roving fiber glass composite pipe by almost (4.5) time. The internal pressure use in woven roving carbon composite pipe was great significantly from the woven roving fiber glass composite pipe by almost (3) times. The most dangerous region is found in the inner arc of the curved pipe (intrude) of curve pipe.
