The aim of this study was to investigate the mechanical and thermal properties of composite pipes based on epoxy resin and glass fibers produced by filament winding (FW) technology. Epoxy resins are widely used polymers in FW composite structures. The thermal characterization of the neat epoxy resin, curing, and post-curing characteristics for the determination of polymerization and glass transition temperature was performed, which is important for the mechanical properties of polymer composite pipes. In the present work, the applicability of the full factorial experimental design in predicting the hoop tensile and compressive strengths of glass fiber/epoxy resin composite pipes was investigated. The composite pipes in accordance with the 23 full factorial experimental design by using of three parameters and two levels of variation were prepared. The winding speed of the composites was taken to be the first factor, the second was the fiber tension, and the third was winding angle. T...
Thermal Stability and Hoop Tensile Properties of Glass Fiber Composite Pipes
International journal of engineering research and technology, 2015
Aim of this work is to present the thermal properties and mechanical behaviour of glass fibre/epoxy resin filament wound tubular structures winded with different winding angles. Conducted thermal analysis have demonstrated thermal stability of used epoxy resin system even at temperatures higher than 130oC and small percent of weight loss until temperature of 350oC. With help of split-disc test hoop tensile strength of manufactured composite samples was investigated. Received results have confirmed the expectations that use of higher winding angle in filament winding technology lead to better mechanical properties of composite tubular structures subjected under internal pressure. Also, fibre-matrix deboning was determined as failure mechanisms by all samples. SEM images have confirmed good merger between reinforcement and the matrix.

Design of polymer composite pipes produced by filament winding technology
2016
The aim of this study is to investigate the design of continuous fiber reinforced composite pipes, 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. 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 – fiber tension and the third – winding angle. The first factor low and high levels were chosen to be 525 m/min and ...
EXPERIMENTAL CHARACTERIZATION OF FILAMENT WOUND GLASS/EPOXY AND CARBON/EPOXY COMPOSITE MATERIALS
Composites have been used extensively in application such as pipes and pressure vessels. Therefore there is a need for further studies on the properties of these materials. This paper presents the results from a series of tensile tests on the mechanical properties of composite materials. Specimens cut from pipes made from composite materials were tested under internal pressure loadings have been tested by using a series of ASTM Standards test methods for mechanical properties.

Quality of Life (Banja Luka) - APEIRON, 2016
In the present work, the attempt was made to assess the applicability of the full factorial experimental design in predicting the hoop tensile strength of glass fi ber/ epoxy resin composite pipes by using of a split disk specimens. Split disk tension tests, provide reasonably accurate information with regard to the apparent tensile strength of composite pipe. In the study we used a number of composite pipes with different fi ber orientation, fi ber tension and velocity of the winding. The composite pipes were made by using of fi lament winding technology includes winding of resin impregnated fi bers into a tool and hardening of the wound structure. The preparation of the composite experimental samples was conducted in accordance with the 2 3 full factorial experimental design. The winding speed of the composites was taken to be the fi rst factor, the second was the fi ber tension and the third winding angle. The fi rst factor low and high levels were set at 5,21 m/min and 21 m/min, respec tively, for the second factor-at 64N and 110N, respectively, and for the third factor-at 10 0 and 90 0. To approxi mate the response i.e. the hoop tensile strength of the composite pipes within the study domain (5,25-21) m/min x (64-110)N x (10-90) 0 , the fi rst order linear model with the interaction was used. The infl uence of each individual factor to the response function was established, as well as the infl uence of the interaction of the two and three factors. We found out that the estimated fi rstdegree regression equation with the interaction gave a very good approximation of the experimental results of the hoop tensile strength of composites within the study domain.
Filament Wound structures are a kind of FRP composites that are being extensively used in many engineering fields because of their inherent advantages. This work involves the manufacturing technology viz. the filament winding technique to fabricate composite tubes. A step by step procedure of the fabrication process of tube is explained. The effectiveness of the FRP cylinders is evaluated by filling the E-Glass fibres in different orientation angle. The experimental results show that the cylinders having angle closer to the axial direction of the cylinder carrying more load capacity in comparison to normal FRP tubes. The Filament wound structures are able to effectively confine the fibres, thereby increasing their strength. To validate the results obtained from the experiments a 3-D finite element model of the filament wound tube was developed using NASTRAN in Unigraphics software. The nonlinear behaviour of the materials used in the experiments was incorporated into the FEA model by considering the appropriate stress-strain relationships. The behaviour of the confined composite cylinder was modelled using a Von-Mises stress criterion.are already defined on the style sheet, as illustrated by the portions given in this document.

Theoretical and Experimental Bending Properties of Composite Pipes
2015
Aim of this work is to determine the theoretical and experimental properties of filament wound glass fiber/epoxy resin composite pipes with different winding design subjected under bending. For determination of bending strength of composite samples three point bending tests were conducted. Good correlation between theoretical and experimental results has been obtained, where sample N4 has shown the highest value of bending strength. All samples have demonstrated matrix cracking and fiber failure followed by layers delamination during testing. Also, it was found that smaller winding angles lead to an increase in bending stress. From presented results good merger between glass fibers and epoxy resin was confirmed by SEM analysis. Keywords—Bending properties, composite pipe, winding design.
Mechanics of Composite Materials
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.
