Pipes that are light in weight are necessary for convenience and to reduce the cost of transportation and installation. A new design of glass fiber reinforced plastic (FRP) pipe with a bamboo and veneer layer is presented in this paper. The core layer of the sandwich structure of the pipe wall is made of bamboo and veneer, and the inner and outer layers are FRP. Range analysis and variance analysis of orthogonal experiments were conducted to investigate the effect of fiber stress, winding angle, and core material on the mechanical performance of the pipes subjected to shearing and parallel-plate loading tests. The results indicated that the new design of FRP pipe with a bamboo and veneer layer was feasible, and the pipe had better mechanical performance with a fiber stress of 300 N, a winding angle of 30°, and a core material of bamboo. Core material was the most influential factor in mechanical performance. The average density of pipes was 0.94 g/cm 3 , approximately half that of the glass fiber reinforced plastic mortar (GRPM) pipes. The FRP pipe offered advantages in terms of weight savings and improved mechanical performance, and it showed a great application potential for the future.

“…This angle is commonly encountered since the netting analysis suggests that this is the optimum angle to use in piping systems where the ratio of applied hoop to axial stress is 2:1 [13]. The stress components induced in each ply have to be calculated when the pipe is subjected to internal pressure.…”

The effects of elevated temperatures on the performance of glass-reinforced epoxy (GRE) pipes under multi-axial loadings were investigated. Finite element software was used to develop the layers of the winding angle on GRE composite pipes. The simulations of the closed-ended pipes' performance under internal pressure loadings of various hoop to axial stress interactions were observed, then the failure strength was illustrated in the form of a failure envelope. Five different stress ratios ranging from pure axial loading 0:1, 1:1, 2:1, 4:1 and pure hoop 1:0 were tested at elevated temperatures (room temperature (RT), 65°C and 95°C) respectively. The first ply failure (FPF) for GRE pipes was predicted based on Tsai-Wu failure criteria. The results show that the highest temperature reduced the strength of the GRE pipes since the hoop and axial stress decreased with increasing temperature and thus the mechanical properties of the GRE pipes were degraded with the increase of temperature. Both showed a strong dependence on the stress ratio and test temperatures. Moreover, as the temperature increases, the glass fibres become more ductile and cause the failure envelopes to shrink towards the origin and become slightly narrower to accommodate the increase in strength of the composite pipes. It is shown that the initial failure stress based failure envelope at elevated temperatures generally degraded, except for the 2:1 loading where the initial failure stress increased.

“…Several studies were carried out in order to determine the influence of FW parameters on the mechanical behavior of structures. For instance, Krishnan et al [5] evaluated the influence of the winding angle in composite tubes subjected to multiaxial cyclic pressure loadings. Failure envelopes showed a strong dependence on stress ratio and winding angle, with [±45]4, tending to be axially dominant, and [±63]4 performing better under high hoop-dominant loading.…”

Manufacturing characteristics of the filament winding process, such as the formation of a winding pattern, are usually disregarded in conventional numerical models. However, they could significantly affect stress and strain fields in thin-walled composite shells. This work presents an efficient way to realistically model the filament winding mosaic pattern in composite cylindrical shells under axial compression. The study comprises the linear finite element (FE) Eigenvalue and Eigenvector buckling model of thin-walled composite cylindrical shells using commercial software. A conventional model was developed and an optimization algorithm was used to find the highest Eigenvalue. After the optimum fiber angle was found, it was used for winding pattern drawing and modeling. Three winding patterns were modeled: 1/1, 3/1 and 5/1, where the numerator means the number of diamonds around the number of circumferences indicated by the denominator. The optimum angle-ply fiber layout found was [±30], which reached the highest critical buckling load. The winding pattern influenced the critical buckling load, and the 1/1, 3/1 and 5/1 patterns showed critical buckling loads of 11.237, 11.173 and 11.194 kN, respectively, whereas the conventional modeling approach indicates a critical load of 8.574 kN. 1.
