  • From static properties to fatigue life: comprehensive evaluation of unidirectional and woven flax fiber composites for structural applications

    Polymer Composites, 2026
    The development of additively manufactured continuous fiber‐based polymer composites has received remarkable attention in developing next‐generation composite materials for numerous structural and non‐structural applications. The present study used an FDM‐based 3D printer to fabricate continuous glass fiber/Onyx composites (with and without holes) utilizing three infill patterns (solid, triangular, and gyroid). The open‐hole tensile properties of the composites were evaluated under quasi‐static tensile loading. The initiation and propagation of damage during testing were captured and analyzed using DIC. For specimens with holes, triangular infill provided the highest tensile strength (183 MPa), followed by solid (172 MPa) and gyroid patterns (167 MPa). The solid infill exhibited the highest tensile strength (278 MPa) for specimens without a hole, followed by triangular (264 MPa) and gyroid (252 MPa) infill patterns. For the composite with a hole, the gyroid infill exhibited the highest specific stiffness (735 MPa/g), followed by 720 and 700 MPa/g for triangular and solid infill, respectively. DIC results depict infill patterns, and stress concentrators significantly influence the damage initiation and propagation in the composites. Fractographic analysis revealed that composites with holes and solid infill patterns primarily failed due to longitudinal splitting at the gauge center. In contrast, those with gyroid and triangular infill patterns exhibited lateral failure.

  • Recent Advancements in Epoxy Resins: Imine, Transesterification, and Disulfide Vitrimer Systems
    Sathyaraj Sankar Lal, Sekar Kannan, Favas Edavankaran, Ujendra Kumar Komal
    Polymers for Advanced Technologies, 2026
    The exceptional dimensional stability, mechanical strength, and resistance to heat and chemicals have made epoxy resins essential materials in numerous applications, such as automotive and aerospace components, the appliance industry, decorative paints and coatings, electronic potting applications, biomedical devices, and industrial equipment. However, due to their highly crosslinked thermoset nature, epoxy resins are not reprocessable, repairable, or recyclable, which has led to a significant amount of material waste at the end of their service life. With increasing environmental awareness and cost pressures, there has been a growing demand over the past decade to develop epoxy systems that can be reprocessed through molding or remelting. In this context, vitrimers have emerged as a promising alternative, enabling, in principle, recyclability and reparability through dynamic covalent chemistry. These properties make vitrimers a potentially powerful class of sustainable polymer materials, extending beyond the use of slowly recyclable plastics. This paper provides a comprehensive overview of epoxy vitrimers, with particular emphasis on systems incorporating dynamic bonds from the imine, ester, and disulfide families, as well as composite formulations and the latest advances reported in this rapidly expanding field.
  • Investigation of the mechanical response of MWCNTs infused carbon/glass fiber-based hybrid composites using digital image correlation
    Somaiah Chowdary Mallampati, Ujendra Kumar Komal, P. S. Rakesh, P. Barman
    Construction and Building Materials, 2025
    The development of hybrid polymeric composites with fillers and balanced mechanical properties has gained popularity due to their remarkably high strength-to-weight ratio, damage resistance, and multifunctional properties. In the current experiment work, epoxy-based composites reinforced with carbon (C), glass (G), carbon/glass (C/G), and carbon/glass with varying (0.25, 0.5, and 0.75 wt%) of multi-walled carbon nanotubes (MWCNTs) were developed using vacuum assisted resin transfer molding (VARTM) (for hybrid composites) and vacuum bagging (for hybrid composites with MWCNTs). The tensile behavior of the developed composites has been investigated using the digital image correlation (DIC) technique to capture full-field strains and displacements. The variation in the displacement of composites and distribution in strain in two principal directions under tensile loading has been captured and analyzed using DIC. The hybrid composite made of C/G with 0.25 wt% of MWCNTs showed a maximum tensile strength of 391 MPa among all the hybrid composites. Adding optimized MWCNTs to the hybrid composites improved stiffness, load transfer, and interfacial bonding between the constituents, which was further investigated through DIC strain mapping. The fractured surface of the tensile specimens and the influence of MWCNTs addition in the composites at the micro and nano levels have been examined using SEM. The current study concludes that adding MWCNTs into hybrid polymeric composites can achieve a balanced and multifunctional property for several sophisticated and advanced engineering applications.
  • Investigation of the structural performance and failure mechanisms of 3D printed continuous carbon fiber-based composites
    Ujendra Kumar Komal, Amir Hamza Siddiqui, Asim Tewari
    Polymer Composites, 2025
    Additive manufacturing of continuous fiber‐based polymeric composites has attracted global attention. This contemporary technology enables the flexibility of manufacturing customized, partially and fully functional, and advanced composite components for numerous semi‐structural and structural applications. The current study investigates the structural performance of 3D‐printed carbon fiber‐based composites in the context of tensile, flexural, and high‐cycle fatigue. The crucial S‐N curves for the unidirectional (UD) (0°) and cross‐ply (CP) (0, 90) composites have been plotted. The dominating failure mechanisms responsible for the failure of 3D printed composites under tensile, flexural, and high cycle fatigue loading at the micro‐scale have been thoroughly investigated. The influence of fiber orientation on the failure mechanisms under different structural loading has been rigorously studied. The current findings conclude that cross‐ply (0, 90) composites exhibited superior fatigue performance than the unidirectional composites when investigated at 70% of their ultimate tensile strength. The current investigation reveals that the formation of voids during 3D printing and majorly during loading is one of the leading causes of the failure of additively manufactured composites under mechanical and cyclic loads. The fiber pull‐out, fiber breakage, de‐bonding, and voids are the dominating failure mechanisms observed under tensile loading. In addition to the failure mechanisms listed under tensile loading, matrix fractures have also been observed under flexural loading. The dominating failure mechanisms differed for UD, CP (0, 90), and CP (45, −45) composites.Highlights Investigated tensile, flexural, and fatigue properties of continuous fiber 3D‐printed composites. Examined failure mechanisms under tensile, bending, and fatigue loading. Developed test coupons with built‐in tabs for tensile and fatigue testing. Cross‐ply composites showed better fatigue performance than unidirectional.

  • Sustainable Treatments of Pineapple Leaf Fibers for Polylactic Acid Based Biocomposites
    Ujendra Kumar Komal, Inderdeep Singh
    Journal of Natural Fibers, 2022
    Sustainable composite materials based on biopolymers and natural fibers have attracted remarkable consideration globally due to their tremendous potential for a variety of applications. However, the poor compatibility among the natural fibers and biopolymers causes the reduced mechanical properties of the biocomposites, limiting their application spectrum and acting as one of the major barriers to commercialization. Therefore, surface modification of fibers using chemicals has been explored by several authors. However, most of the chemicals used are hazardous to the environment when used commercially. In the current investigation, sustainable chemicals (sodium bicarbonate and borax) were used to modify the surface of the pineapple leaf fibers (PALFs). Untreated and treated PALF/polylactic acid biocomposites were manufactured using the commercial-scale injection molding machine. The selected chemical treatment strategies were found to be efficient for improving the strength, crystallinity, and thermal properties of pineapple leaf fiber (PALF). An improved adhesion among the fibers and matrix, enhanced strength (tensile, flexural, and impact), and modulus (tensile and flexural) of the biocomposites were also recorded after the treatment. A robust structure-property linkage for PALF and their biocomposites has also been developed.
