  • Influence of Graphene Oxide and Silanized Graphene Oxide on the Structural and Thermal Behavior of GFRP Composites
    Kaushal Kumar, Ankita Singh, Rahul Chamola, Subhankar Das, Nazrul Islam Khan, et al.
    Polymer Composites, 2026
    This study examines the impact of graphene oxide (GO) and silanized graphene oxide (SiGO) on the mechanical as well as thermal properties of glass fiber/epoxy (GFRP) laminated composites. GO was functionalized with 3‐aminopropyltriethoxysilane (APTES) to yield SiGO, which led to improved dispersion in the epoxy along with interfacial bonding. Laminates were manufactured via hand lay‐up and by integrating 0.1–1.0 wt.% of GO and SiGO using ultrasonic dual mode mixing (UDMM) technique in GFRP. Mechanical testing unveiled pronounced enhancements, with 0.7 wt.% SiGO composites exhibiting ~45% higher tensile strength, 98% higher tensile modulus, 76.8% higher flexural strength, and 89.9% higher flexural modulus relative to neat laminate, credited to improved filler dispersion as well as matrix–filler adhesion. Thermal assessment implied elevated decomposition temperatures, higher char residue, and increased glass transition temperatures, affirming improved thermal stability. SEM fractography backed these outcomes. The results exhibit that silanized GO efficiently improves mechanical strength and thermal stability in GFRP laminates, providing a potential for high‐performance composites in state‐of‐the‐art engineering applications.

    Polymer Composites, 2025
    Achieving high electromagnetic interference (EMI) shielding effectiveness alongside outstanding mechanical properties remains a notable challenge for carbon fiber‐reinforced epoxy (CFRE) composites. Herein, an efficient method for interface modification is proposed to produce hybrid CFREs with enhanced EMI shielding capabilities and exceptional mechanical properties. This study introduces the fabrication of CFRE composites incorporating APTES‐modified MXene sheets into the epoxy matrix (AM‐CFRE), demonstrating significant improvements in structural integrity and EMI‐shielding performance. Compared to pristine CFRE (P‐CFRE), AM‐CFRE exhibits enhanced mechanical properties with a 39.63%, 35.41%, 65.01%, 29.71%, 34.9%, and 34.21% increase in tensile strength, Young's modulus, tensile toughness, flexural strength, flexural modulus, and short beam strength, respectively. Furthermore, AM‐CFRE demonstrates a ~50% improvement in EMI shielding effectiveness in the X‐band compared to P‐CFRE. The lightweight AM‐CFRE structure, with strong mechanical strength and remarkable EMI shielding, shows great potential for various applications, particularly in protecting avionics within the aerospace and defense industries.Highlights MXene was synthesized via HF etching, and its surface was modified with APTES. Hybrid CFRE was made with an epoxy system containing surface‐modified MXene. Exceptional mechanical and thermo‐mechanical properties were achieved in Hybrid CFRE. AM‐CFRE achieves EMI shielding effectiveness of 25.36 dB in the X‐band.

    Babloo Roy Gautam, Nazrul Islam Khan, Nitya Nand Gosvami, Subhankar Das
    Proceedings of the Institution of Mechanical Engineers Part L Journal of Materials Design and Applications, 2025
    Self-healing polymers (SHP), inspired by nature, are materials that have the ability to recover themselves from various physical damages in the presence of different inducing environments. The self-recovering property indicates the capability to heal the cracks in their very nascent stage at their micro or nano-level size and provides a door to prevent them from any major catastrophic failure. In this article, a comprehensive review with updated reported work on various types of self-healing mechanisms and their advantages and limitations has been discussed, along with their applications. The main focus of the review has been aligned with the challenges and future scopes associated with the exploration of self-healing concepts for industrial coating applications. The different extrinsic, intrinsic, and combined healing mechanisms have been explained, along with their application in coating. Finally, the recent status of healing technology and future research trends has been discussed in this review article.
  • Effect of polyethylene glycol on rheological, thermo-mechanical, and tribological behavior of epoxy
    Ankita Singh, Rahul Chamola, M. S. Goyat, Bappi Paul, Subhankar Das
    Polymer Engineering and Science, 2025
    Over the past few years, polyethylene glycol (PEG) has been recognized as an effective blend to enhance the mechanical properties of brittle epoxy. However, the literature contains limited systematic studies evaluating PEG's role in improving epoxy performance. Therefore, a systematic approach was employed in the present study to assess the impact of varying weight percentages of PEG on the viscosity, thermo‐mechanical, and tribological properties of epoxy. Adding 10 wt% PEG (PEG‐10) in epoxy is identified as the threshold limit. With PEG‐10, the viscosity significantly decreased by approximately 78%, while fracture toughness, tensile strength, tensile modulus, and failure strain improved by 59.5%, 38.5%, 37.8%, and 54%, respectively, compared to neat epoxy. Additionally, the wear rate was significantly reduced by 92% compared to neat epoxy, though thermo‐mechanical and flexural properties were slightly compromised. Furthermore, the failure mechanisms of the tensile fracture surfaces and wear tracks of epoxy–PEG blends were examined to understand PEG's role more comprehensively.Highlights A Significant drop in the viscosity of epoxy resin is achieved with the help of PEG‐400. PEG‐400 is mixed with epoxy resin to improve its fracture toughness and tensile properties. A 92% reduction is observed in the wear rate when PEG‐400 is mixed with epoxy resin at 10 wt%.

  • TRIBOLOGICAL AND THERMAL BEHAVIOR OF LOW-LOADING CARBONACEOUS FILLER–REINFORCED EPOXY NANOCOMPOSITES
    Pooja Singh, Swati Sharma, Kaushal Kumar, Shweta, Ganesh Iyer, et al.
    Composites Mechanics Computations Applications, 2025
    Carbonaceous filler-reinforced epoxy is a high-performance nanocomposite used for different industrial applications due to its high strength, stability, conductivity, and high thermal, electrical, and tribological properties. Among various carbonaceous fillers, multiwalled carbon nanotubes (MWCNTs) are one of the most versatile and pertinent carbonaceous fillers for the enhancement of thermal and tribological properties of epoxy nanocomposites. This work highlights the enhancement of wear rate, friction, and thermal properties of epoxy nanocomposites at low contents (0.2 wt.%, 0.4 wt.%, 0.6 wt.%, 0.8 wt.%, and 1.0 wt.%) of MWCNT carbonaceous nanofiller. The pin-on-disc tribometer is used to study the wear rate and coefficient of friction of nanocomposites under dry sliding conditions. From the results of the wear and friction test, it is found that at 0.8 wt.% MWCNT-reinforced composite, the wear rate and coefficient of friction are lowest compared to other compositions and pure epoxy polymer. The specific wear rate and coefficient of friction showed 33.43% and 13.47% lowest values, respectively, as compared to the pure epoxy polymer. Differential scanning calorimetry is used to investigate the glass transition temperature enhancement of the nanocomposites with the addition of low-composition nanofillers. Results found that at 0.8 wt.% MWCNT, the glass transition temperature was maximum and achieved 9% enhancement compared to pure epoxy. The novelty of the work lies in the significant enhancement in the properties after loading of MWCNTs in epoxy polymer under low compositions. These nanocomposites provide alternate low-cost and sustainable materials for automobile applications.
