Stress modeling of pipelines strengthened with advanced composites materials

Analysis of a carbon composite overwrap pipeline repair system

“…Common, FRP systems used for reinforcing pipe walls include glass fibre, aramid fibre, and carbon fibre composites. Toutanji and Dempsey [6] showed that carbon fibre reinforced polymers (CFRPs) perform better than those reinforced with glass or aramid fibres in that they improve the ultimate internal pressure capacity of pipes, significantly enhancing the strength, durability, and corrosive properties of the system.…”

Exact solutions for thin-walled open-section composite beams with arbitrary lamination subjected to torsional moment

“…Especially, the research efforts [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] to obtain analytical solutions for composite beams have been made by many researchers. Wu et al [3] developed an analytical model capable of analyzing the torsional behavior of composite box beams under torsional load without external restraint.…”

Design of fibre-reinforced polymer overwraps for pipe pressure

“…After performing a series of tests on the ArmorPlate Ò , Alexandra and Wilson (1999) proposed guidelines for the use of composite materials in pipeline repairing systems and came up with the stress modelling of pipelines strengthened with FRP under different loading conditions. Another investigation was performed using Glass FRP (GFRP), Aramid FRP (AFRP) and Carbon FRP (CFRP) by Toutanji and Dempsey (2001). The results revealed that CFRP performs better in comparison with AFRP and GFRP when it comes to increasing the burst strength of pipes.…”
