Hoop tensile and compression behavior of glass-carbon intraply hybrid fiber reinforced filament wound composite pipes

Abstract

Abstract The current study presents an experimental investigation aimed at exploring the effects of intraply fiber hybridization on the apparent hoop tensile and compression behavior of glass/carbon filament wound composite pipes by conducting split-disk and external parallel-plate loading tests, respectively. The efficiency of the hybridization process is also analyzed for a variation in fiber orientation by preparing composite pipes of different winding angles. The results show that a deterioration occurs in the apparent tensile strength of hybrid composites because of the weak interfacial adhesion between carbon and glass reinforcements. However, the compression behavior of glass fiber wound composite pipes, in terms of pipe stiffness and the stiffness factor, increases with the inclusion of carbon fiber. The increase in pipe stiffness and the stiffness factor are in the range of 10 and 20 %, respectively. Failure modes of the samples have also been discussed to understand fracture mechanisms. In conclusion, the intraply hybridization exercises significant influence, especially in the apparent hoop tensile characteristics of the pipes.
