  • Mode-I interlaminar fracture behavior of additively manufactured continuous carbon and Kevlar reinforced composites
    Kuldeep Yadav, Vikrant Tiwari
    Mechanics of Advanced Materials and Structures, 2026
    Additive manufacturing aka 3D printing of components utilizing continuous fiber reinforcement is gaining widespread popularity owing to their superior performance, weight saving, low labor and equipment costs, and producing complex shaped objects. However, 3D-printed composites are known to be susceptible to weak interlayer adhesion and layer delamination. Therefore, it is imperative to comprehend the delamination behavior of 3D-printed composite specimens to address the broader applications of additive manufacturing. This article is aimed at experimentally investigating the mode-I interlaminar delamination behavior of 3D printed composite materials having different interface (I/F) materials and orientations. Chopped micro carbon fiber infused Nylon® (aka Onyx) is taken as base specimen material. Additionally, specimen arms of the Double cantilever beam (DCB) composite specimens are 3D printed by utilizing an industrial fused deposition modeling (FDM) printer and their arms are optimally reinforced by continuous carbon fiber layers In addition, continuous Kevlar and carbon fibers are utilized as I/F layer materials. This study attempts to investigate a total of six different I/F material configurations by systematically subcategorizing them in two sections. The three specimens considered in first category are dedicated to investigating the interlayer adhesion and delamination behavior of Onyx layer with adjacent Onyx layer of continuous fiber reinforced layer (Onyx//Onyx, Onyx//Kevlar, and Onyx//carbon). Whereas the remaining three specimen types of second category are dedicated to investigate interlayer adhesion and delamination behavior of continuous fiber reinforced layers only (Kevlar//Kevlar, carbon//carbon, and Kevlar//carbon). Additionally, the print orientation of the I/F layers is also varied to understand the change in delamination behavior of longitudinally and transversely printed I/F layers. The fracture toughness of the specimens is evaluated in terms of strain energy release rate by utilizing the modified beam theory (MBT). Pure Onyx I/F layers are observed to resist crack propagation with maximum resistance owing to excellent interlayer adhesion. The introduction of continuous fibrous layers is observed to reduce the resistance to crack propagation marginally. Additionally, the resistance to crack propagation is observed to be marginally better for transversely printed I/F layers than the longitudinally printed layers.
  • Investigation on delamination behavior of additively manufactured Kevlar and carbon composites subjected to Mode-II loading conditions
    Kuldeep Yadav, Vikrant Tiwari
    Polymer Composites, 2025
    With increased design and manufacturing complexity of required components in various industries, additive manufacturing of composites shows great potential in the production of next‐generation lightweight structures. Fused filament fabrication (FFF) is one such method of composite fabrication where components are 3D printed by heating a filament material above its gel temperature and depositing it on previously printed layers. The composite components fabricated by FFF are known to be susceptible to delamination owing to weak interlayer adhesion. This experimental study is an attempt to understand the underlying interlaminar delamination phenomenon of FFF‐printed end‐notched flexure (ENF) composite specimens subjected to mode‐II loading conditions. The composite specimens are 3D printed by an industrial FFF printer utilizing micro carbon fiber infused Nylon aka Onyx as the base specimen material. Either Onyx, continuous carbon fibers, or continuous Kevlar fibers are used as interfacial materials for the current study. In addition, the ENF composite specimen arms are optimally reinforced with continuous carbon fibers in pre‐selected layers of the specimen. The first category of specimens comprising three different interface material configurations aims to understand the delamination behavior of Onyx layers with other Onyx layers or continuous fiber reinforced layers (Onyx//Onyx, Onyx//Kevlar, and Onyx//carbon). On the other hand, the second category comprising three other different interface material configurations aims to understand the delamination behavior of continuous fiber reinforced layers in the composite specimens (Kevlar//Kevlar, carbon//carbon, and Kevlar//carbon). In addition, the relative orientation of interfacial layers is also varied to investigate the effect of print orientation on the delamination behavior of ENF specimens. Digital image correlation (DIC) is employed to accurately quantify the extent of crack propagation by accessing full‐field shear strain distribution of the front face of specimens generated during a three‐point bend loading event under quasi‐static loading conditions. The resistance to crack initiation and propagation is observed to be highly dependent on interfacial layer materials and their relative orientation.Highlights Interlaminar fracture of additively manufactured composites under mode‐II loading. DIC technique is used for quantifying crack advancement during loading events. Twelve different interfaces of additively manufactured composites are analyzed. Effects of print orientation and interface material type are investigated. Delaminated surfaces are examined to correlate underlying fracture mechanisms.

  • Experimental and numerical investigation of monolithic and homo-stacked target plates of AA2014-T6 subjected to blunt and hemispherical projectiles
    Anoop Kumar Pandouria, Rohit Kumar, Kuldeep Yadav, Purnashis Chakraborty, Vikrant Tiwari
    Proceedings of the Institution of Mechanical Engineers Part C Journal of Mechanical Engineering Science, 2024
    In this article, the ballistic response of thin sheets of the aluminium AA2014-T6 in monolithic and homo-stacked configurations was studied experimentally and numerically. Firstly, the experiments were performed on 1 and 2 mm thick monolithic and 1 + 1 mm homo-stacked target plates with blunt and hemispherical nose shape projectiles at different velocities. All experiments were carried out using a single stage gas gun coupled with two ultra-high-speed cameras. Transient response and full-field out-of-plane displacement of the target plates are analysed using 3D digital image correlation technique (3D-DIC). During the investigations the nose shapes of the projectile were found to have a significant influence on both out-of-plane displacement and failure mode of the impacted plates. The target plate is penetrated by shear plugging in the event of a blunt projectile, whereas for a hemispherical projectile impact, penetration occurred from first tensile stretching and then shear plugging. It was also found that the ejected plug and hole size are almost the same and equal to the projectile’s diameter for blunt projectiles. While in case of hemispherical impact both were less than the projectile’s diameter. Secondly, 3D FE simulations for all the configurations were also performed using J-C plasticity and damage criteria. The simulation results were found to be in accordance with the experimental results in terms of failure mode, ejected plug size and plate hole size. Detailed Russel error analysis was also performed to validate the correlation between the experimental and numerical data.
