The aim of this study is to investigate the mechanical properties of continuous fiber reinforced composite tubes, produced by filament winding technique. For this purpose, the full factorial experimental design was implemented. When designing filament winding composites three major factors are the most important: fiber orientation, fiber tension and velocity of the filament winding. The ultimate target is to achieve the composite pipes with good characteristics as bearing material for construction with the lowest possible weight. The filament winding composite pipes were made of glass fiber and epoxy resin. Glass fibers have good mechanical and thermal properties, and due to this reason, they are usually selected as the reinforcement material for filament winding technique. Thermoset or thermoplastic resin systems are usually used for impregnation of the continuous fibers in filament winding. Most commonly, epoxy resins are used due to their wide range of thermal and mechanical properties. The preparation of the composites was done by applying the 23 full factorial experimental design. For the purposes of these investigation, eight test specimen configurations are made and on the basis that, test results should provide material properties useful in the design stage. The velocity of the filament winding was taken to be the first factor, the second – fibre tension and the third – winding angle. The first factor low and high levels were chosen to be 5,25 m/min and 21 m/min, respectively, for the second factor – 64 N and 110 N, respectively and for the third factor – 100 and 900, respectively. The effect of a filament-winding processing variables on longitudinal and hoop tensile and bending properties of the prepared composites will be investigated according to American Society for Testing and Materials (ASTM) standards.
