“…Nowadays, composite FRP piles have been an innovative solution for composite columns. There are a great number of experimental and analytical studies in the literature focusing on hoop stress behavior of glass-epoxy composites pipes [20,[24][25][26][27][28][29][30].…”

“…Filament wound (FW) composite tubes are the most common tubes in the industry. The mechanics and characterization of FW composites under axial and lateral compression, 1,2 hydrostatic burst, [3][4][5] impact, 6,7 tensile, and bending, 8,9 torsion, 10 functional failure, 11 creep, 12,13 fatigue, 14,15 and combined loading 16 have been well studied and understood in the literature. For instance, Rafiee and Torabi 5 and Rafiee et al 11 studied the first ply-failure, functional, and structural failures of glass fiber reinforced polyester (GFRP) pipes deterministically and stochastically.…”

Mechanical properties and damage mechanisms of closed circular preforms and overlapped stitched composite tubes under lateral compression, impact, and hydrostatic pressure were studied. The functional failure pressures of the tubes with different boundary conditions were determined and compared. Stitch at the overlapped zone creates stress risers that lead to premature functional failure at a hydrostatic pressure at ∼1/3 of the theoretical maximum pressure of the tube as delamination occurs at the overlapping region. Seamless tubes reached values close to theoretical operating hydrostatic pressures before leakage was observed at the tube ends. The deflection of the overlapped stitched tube due to lateral compression is less than the deflection in the seamless tube, and it is limited to 5% of the inner diameter using the Spangler equation. Brittle kinks, cracks, and delamination occur in overlapped stitched tubes while seamless tubes regain the shape with limited localized cracks after unloading. The fabric architecture of a seamless tube allows for the reorientation of fiber tows as cracks develop in the matrix, thus resulting in a lesser extent of damage when the tube is subject to impact.

“…In the field of civil engineering, it is no longer a novelty to use both plastics or glass fibers reinforced plastics (GFRP) to manufacture pipelines used for: Potable water supply and transportation; chemical installations for transporting the corrosive fluids; sewage systems for wastewater [1]. In such GFRP pipes, thermoset resins (polyester, vinyl-ester, epoxy) are usually used as a matrix material to bond glass fibers [1,2,3,4]. Flexible composite pipes made of high-temperature polythene (PE-RT) reinforced with aramid fibers are thermo-stable with a temperature that is lower than 95 °C and with the internal pressure that is lower than 4 MPa [5].…”

“…It is known that GFRP used to manufacture the manhole covers are sensitive to environmental conditions (moisture, thermal cycles, UV rays) because the properties of the polymeric matrix change under long-term environmental effects [1,2,3,10,11,12]. In case of the vinyl-ester resin, some properties (glass transition temperature, degree of crosslinking, tensile strength) increases with respect to exposure time to outdoor conditions up to 12 months.…”

This research concerning the topic, pursues the design, manufacturing, analysis and testing of the manhole cover that may be used in pedestrian networks. Although there are certain commercially available manhole covers made of glass-reinforced composites, there are a few papers published related to the modelling, simulation and mechanical testing of such parts. Herein, the manhole cover is made of the sandwich composite. The novelty of this kind of cover is to use an oriented strand board (OSB) as the core between two sides containing layers, which are reinforced with glass fibers. The OSB core leads to the increase of the stiffness-weight ratio. The paper describes the materials corresponding to the layers of the composite cover, geometry of the cover, technology used to manufacture the bending specimens and cover tested. Specimens made of materials that correspond to each layer of the cover, are tested in bending in order to determine their mechanical properties (flexural strength and flexural modulus). Bending tests and testing of the cover are also described. The composite manhole cover is also analysed by the finite element method to obtain the state of stresses and strains. The strains of the manhole cover are experimentally measured by using the tensometric method. Finally, comparing the strains with the strains experimentally measured validates the numerical simulation model.
