Keywords: wound structures, glass-reinforced polyester, angle-ply reinforcements; Composite Pipes. The design of composite structures is always a very delicate task to ensure that an antisymmetrically wound laminate had the performance required. Our study was carried out with the aim to optimize the performance/ cost ratio of these materials. It consisted in the design and manufacture of orthotropic filament-wound glassreinforced polyester (GRP) pipes with different fiber orientation (± 45, ± 55, and ± 70°). Experiments on a 500-mm-diameter GRP pipes wound at different angles were carried out in various mechanical loadings, and the data found were compared with results obtained by analytical methods.
1. Introduction The pipe industry has been interested in composite materials since the 1950s. The interest in glass-fiber-reinforced polymer (GFRP) pipes is mainly due to their light weight combined with high mechanical characteristics, good corrosion resistance, and improved fatigue behavior compared with steel and aluminum alloy ones [1, 2]. Furthermore, GFRP pipes have become indispensable in many applications owing to this combination of properties. The pipeline industry has benefited from civil and military investigations by adapting composite materials to its own needs [3, 4]. Nowadays, the use of composite pipes is growing with the possibility of developing high-performance materials, and they are often used in almost all applications to withstand aggressive service, ambient temperature, and environmental conditions [1, 2, 5].

To produce composite pipes, different manufacturing processes have been developed, including centrifugal casting (CC) and filament winding (FW) processes [2]. Of the two techniques, the filament winding method is commonly used for manufacturing high-quality composite structures [6-8]. To produce composite pipes by filament winding, continuous reinforcement elements in the form of rovings (glass, carbon, aramid, etc.) impregnated with a liquid resin (polyester, epoxy, etc.) are used [9, 10]. A cylindrical composite structure is obtained by winding impregnated rovings on a rotating mandrel. The expanding use of these products and the high demands imposed on them is a real challenge to design engineers. Thus, more and more studies are being conducted to investigate these materials w
