Abstract
The focus of this lecture was to investigate the mechanical properties of different glass fiber reinforced composite pipes produced by filament winding technique. Properties of fiber reinforced composites (FRP) arise as a function of its constituent materials, their distribution, and the interaction among them and as a result of it an unusual combination of material properties can be obtained. There are various methods of their manufacturing, but filament winding is a very important and widely used technique for FRP production related to civil engineering. The basis of this technology includes winding of resin-impregnated fibers into a tool and hardening of the wound structure. This technology enables the fibers to be placed into the direction of the load that may be expected during exploitation of construction elements. By varying the winding angle with respect to the mandrel axis, directional strength can be obtained by the loads, which will operate on the finished product. It is essential to know the mechanical and thermal characteristics of filament wound tubes in order to employ them in design applications. Based on the investigation in the fame of this lecture, it can be concluded that from the mechanical point of view there are significant differences in the filament wound pipes with different fiber orientation. Regarding the tensile properties, the bigger winding angle lead to higher hoop tensile properties of filament-wound tubular samples. But, for the transverse compression properties of composite specimens the lower winding angle lead to higher transverse compression properties of the samples. The optimal mechanical properties have the samples on the primary level winded with angle 450. It was noticed a slight influence of the fiber tension but the velocity of the filament winding doesn’t influence on the mechanical properties of the specimens.
