    International Journal of Nanoelectronics and Materials, 2025
    A comprehensive understanding of composite pipe corrosion behavior is essential due to their exposure to diverse chemical environments. This study examines Glass Reinforced Plastic (GRP) composites, commonly employed in underground construction and industrial applications, with a particular emphasis on the rehabilitation of aging sewage pipelines. The investigation focuses on assessing the chemical durability of a multi-layer GRP material reinforced with polyester resin. The chemical resistance of individual layers and the composite as a whole are evaluated before and after immersion in various chemicals for periods of 30, 60, 90, and 180 days. The chemical environments are designed to replicate in-service conditions, including exposure to Sulphuric acid (H₂SO₄), Sodium hypochlorite (NaClO), Methyl ethyl ketone peroxide (MEKP), distilled water, Sodium chloride (NaCl), Propanone (C₃H₆O), Cobalt Octate, and Dimethylacetamide (DMA). Mass loss measurements are used to evaluate changes in chemical composition. The observations from this study assist in estimating the long-term structural health of composite pipes exposed to harsh chemicals found in sewage water.
  • Tailorable deformation and crushing behavior of 3D printed multilayered tetra-chiral lattices: Experiments and finite element modeling
    Johannes Schneider, Prajit Rawte, Priyank Upadhyaya, S. Kumar
    Materials Today Communications, 2025
    This study investigates the tunable auxetic and crushing characteristics of a set of novel, multilayered tetra-chiral (TC) lattices through a combination of experimental testing and finite element (FE) modeling, aiming to uncover how the mechanical properties are affected by layer stacking. Utilizing Digital Light Processing (DLP) to fabricate multilayered lattices from PlasGray photoresin across two distinct length scales, we observe length scale-dependent material properties, which prompt a more in-depth examination of the deformation and failure characteristics of multilayered lattices. The experimental results form the basis for subsequent FE analysis, employing a Drucker–Prager material model combined with ductile damage criteria to investigate the effects of layering on stiffness, strength, and energy absorption characteristics. By tuning the architectural parameters within the FE simulations, we expand the design space, aiming to uncover configurations that exhibit superior mechanical performance. The results indicate that, for a constant mass, bi-layered and multi-layered TC structures exhibit enhanced energy absorption, with increases of 114% and 149%, respectively. This study advances the understanding of layered tetra-chiral lattices and provides a foundation for future efforts to optimize the design and functionality of multilayered structures in various engineering applications.
  • A Sustainable Solution with Improved Chemical Resilience Using Repurposed Glass Fibers for Sewage Rehabilitation Pipes
    Devanand Chelot, Shivnarain Ravichandran, Priyank Upadhyaya
    Recycling, 2024
    This paper introduces a sustainable sewage rehabilitation solution, utilizing repurposed glass fibers for enhanced chemical resilience and environmental conservation. The approach involves dividing a unitary pipe into segments, assembled during commissioning, aiming to reduce installation and transportation costs, particularly in less accessible areas. Each pipe segment comprises a multi-layered glass fiber composite sandwich, joined by an adhesive reinforced with recycled glass fibers. The glass fiber-reinforced plastic (GFRP) pipe features a core of blended sand impregnated with resin, an outer layer for impact resistance, and an inner layer to prevent corrosion. Chemical resilience is assessed through a 10,000 h strain corrosion study exposing both unitary and two-piece circular GFRP pipes to sulfuric acid in a deflected condition. An apparent hoop tensile test evaluates mechanical integrity before and after exposure. The experimental results reveal that the two-piece pipe with a tongue and groove joint (TGJ) with recycled glass fiber adhesive exhibits superior long-term bending stress and failure strain % compared to unitary pipes. This enhancement is attributed to the TGJ’s improved load-bearing capability and chemical resistance. The failure strain % of the two-piece pipe (1.697%) is higher compared to the unitary pipe (1.2613%). The long-term bending stress of the two-piece pipe obtained is 119.94 MPa whereas the unitary pipe reaches 93.48 MPa at the 50-year mark. The cost analysis supports the adoption of the two-piece pipe over unitary pipes due to a 40% reduction in carbon emissions and transportation cost. The novelty lies in the utilization of multi-piece pipes with enhanced chemical resilience, achieved through the incorporation of milled fiberglass reinforcements in the TGJ. Strain corrosion tests take a long time to perform; hence, an accelerated test is needed to improve the current recommended testing standard.
  • Enhanced strength and toughness of repurposed glass fiber reinforced adhesive joints for sewage applications
    Devanand Chelot, Abhishek Tewari, Kumar Shanmugam, Priyank Upadhyaya
    Journal of Adhesion, 2024
    In this study, the enhancement in strength and toughness of multi-piece glass fiber reinforced plastic (GFRP)/GFRP joints was demonstrated. These joints are bonded with repurposed short glass fiber reinforced adhesive and find their application in rehabilitation of sewage pipelines. These short fibers were produced by grinding and milling the fiberglass wastes, collected during the lamination process of pipes. To study the effect of glass fiber content on the mechanical properties of the composite adhesive, short fiber composite (SFC) specimens with varied milled fiber content were tested under flexural loads. A finite element-based numerical homogenization study was carried out on a micro-mechanical periodic unit-cell representing a non-homogeneous SFC to predict the mechanical properties of the microstructure. The dispersion state of fibers and fracture surface characteristics of SFC were analyzed via scanning electron microscopy. Further, the shear strength of the adhesive with and without reinforcement was experimentally evaluated using a lap shear test. Increasing the fiber content in the adhesive transforms it from a compliant state with poor strength into a much stiffer and stronger composite with reduced strain tolerance. The optimized SFC was selected for joining the two segments of the GFRP sewage pipe using a unidirectional composite as a tongue. Subsequently, the tongue-in-groove joints (TGJs) were tested under tension.

  • Experimental Study on Multi-Segmented Circular or Non-Circular Pipes to Determine the Pipe Stiffness

    Key Engineering Materials, 2022
    A study was carried out to test unitary as well as multi-segmental circular and noncircular glass-reinforced plastic pipes under compression. Three pipe shapes were tested (box, semi-elliptical and round) under identical conditions using the ring stiffness method of testing. Hand layup technique was used for manufacturing the pipes. The pipes were designed with inner layers, central core and outer layers. The inner layer acts as the corrosion barrier layer, the core consists of blended sand impregnated with resin and the outer layer acts as the external layer which protects the pipe from impact. Based on the experimental results, it was concluded that multi-segmental pipes are stiffer and more flexible than unitary pipes because of the loading carrying capacity of the tongue and groove joint (TGJ).
