Epoxy-glass fiber composite pipes were fabricated with filament winding machine. Full automation and precise control over the processing parameters are the major advantages of this manufacturing technique. Stacking sequence is one of the important processing parameters on which the properties of filament wound components depend to a large extent. This paper comes up with a comparative damage analysis of traditional composite pipes (TCPs) of stacking sequence [±55]6, and functionally graded composite pipes (FGCP) of stacking sequence [70-55-40-40-55-70]. The stacking sequence in FGCP was chosen such that the average stacking angle is retained the same as of TCPs, i.e. [±55]. An impact analysis of these pipes was carried out. Impact energy of 45 J was applied on both pipes and damage was quantified using back-lighting technique. It was observed that the damage occurred in FGCPs was 30% lesser compared to TCPs.

Structural Scale

Filament winding (FW) is one of the most common techniques for manufacturing composite pipes. The material properties and failure mechanism of composite pipes depend largely on winding pattern. In this study a micro mechanical approach for filament wound composites (FWCs) is pursued. A diamond-shaped repeated unit cell (RUC) is first constructed which characterizes the micro architecture of FWC pipe, such as winding angel, shift between successive circuits and the area of local undulation region. The micro mechanical model is embedded into commercial FEM code of ABAQUS as user-defined subroutine thus the link between the analyses in macro engineering structural scale and in micro material structural scale is established. By averaging micro stiffness constants over the cell macro ones needed for engineering structural analysis can be obtained. On the other hand, the macro structural analysis provides average stresses/strains of the cell locating at any concerned region of the macro structure for local stress and damage analysis. Effects of tow undulation caused by tow crossover on micro stresses are taken into accounted. The model is applied to glass/epoxy wound pipes with various winding angles and winding shifts. Mechanical properties are predicted and damage evolutions are simulated. The effects of delamination damage, usually introduced by lateral low velocity impact, on stiffness and ultimate strength of FWC pipe are also investigated.

Composite Pipes

In general, filament winding technique is used to fabricate the composite pipes using continuous fiber and matrix resin. In this study, fly ash based geopolymer resin composites reinforced by continuous glass fiber were used for fabrication and synthesized by different curing and sintering temperature, different pattern and different viscosity of geopolymer. The effects of that parameter on the product were investigated. The compressive properties of the resulting composite were determined on an Instron Universal Testing under compression mode and the results show that the helical pattern with low viscosity cured at 75°C give the highest strength.

Full Factorial

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 fiber/ 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 fiber orientation, fiber tension and velocity of the winding. The composite pipes were made by using of filament winding technology includes winding of resin impregnated fibers into a tool and hardening of the wound structure. The preparation of the composite experimental samples was conducted in accordance with the 23 full factorial experimental design. The winding speed of the composites was taken to be the first factor, the second was the fiber tension and the third winding angle. The first factor low and high levels were set at 5,21 m/min and 21 m/min, respec­tively, for the second factor – at 64N and 110N, respectively, and for the third factor – at 100 and 900. To approxi­mate 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 first order linear model with the interaction was used. The influence of each individual factor to the response function was established, as well as the influence of the interaction of the two and three factors. We found out that the estimated first-degree 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.

The current composite pipes such as E-glass have better properties compared to metallic pipes. However, these pipes are prone to failure during its service life. In contrast, natural fiber such as basalt fiber composite pipes has better mechanical characteristics compared to current composite pipes. Hoop tensile, longitudinal tensile and internal pressure loads were carried out through experimentally and numerically investigation on the basalt/epoxy and E-glass/epoxy pipe performance. The basalt/epoxy and E-glass/epoxy composite pipes have been manufactured with ±55o winding angle using dry filament winding with impregnation of epoxy resin used Vacuum Infusion Process (VIP) technique and investigated. Basalt and E-glass composite pipes with winding angles of ±45o, ±55o, ±65o, ±75o were fabricated in order to assess the optimal winding angle which can resists the subjected loads. There were good agreement between numerical and experimental results have been recorded. For internal pressure test, the basalt pipes have more internal pressure carrying capacity more than E-glass by 2.41%. Through this investigation, can be concluded that the natural based fiber of basalt can be used as a suitable replacement than E-glass, has further advantages of being cheap, abundant, renewable and easily recyclable. The also possess high strength, excellent flexural stiffness to cost ratio and low thermal conductivity
