“…Compared to thermoset composites, thermoplastics offer advantages such as high productivity, high damage tolerance, improved damping behavior, recyclability, formability, repairability, and cost‐effectiveness 1 . Therefore, designers and engineers prefer thermoplastics and a wide spectrum of industries are moving toward thermoplastic composites to make more robust, fuel‐efficient, and lighter structures 2–6 . However, since they are available in pellet or film form, they must be melted at high temperatures for the injection molding process.…”

The preference for thermoplastic composites over thermoset ones is steadily growing, especially in constructing resilient, lightweight, and fuel‐efficient structures in industrial settings due to their recyclability and superior energy absorption. Elium®, an acrylic‐based thermoplastic resin, offers enhanced stiffness and improved toughness at room temperature. Investigation into elium‐based composites with diverse fiber reinforcements has revealed elium's potential as an alternative to traditional thermoset epoxy resins. This study explores recyclable elium resin as an adhesive for creating curable and non‐permanent joints in various elium‐based composites. Various joining techniques, including adhesive bonding, mechanical joints, and hybrid bolted/bonded connections, were assessed, with hybrid bonded/bolted (HBB) joints emerging as a preferred solution for structures requiring higher load‐carrying capacity. The study's results indicate that, when using elium adhesive, elium‐hybrid bolted/bonded (HBB) joints demonstrate superior mechanical strength compared to their epoxy counterparts, resulting in improved toughness and stiffness values for each type of composite material. In addition, the research demonstrates superior load‐bearing strengths in bonded glass/elium composite joints using elium adhesive compared to bolted joints, with HBB joints featuring elium adhesive displaying even higher load‐bearing strengths. This research highlights the potential of elium‐based composites and adhesives in various industrial applications, enabling the production of lightweight, robust structures with exceptional damage tolerance.Highlights Investigates recyclable elium resin for curable and non‐permanent joints.

Natural fiber‐reinforced polymer composites (NFRCs) are increasingly favored over synthetic fiber‐reinforced alternatives due to their beneficial properties and environmental sustainability. Mechanical properties of composites are critical to ensure optimized utilization of NFRCs. Here, this research explores the effects of different fiber parameters on the tensile strength of high‐density polymer composites reinforced with banana fiber and utilizes the Taguchi method for both experimental and statistical analysis of the outcomes. Three different parameters are considered here: weight fractions, fiber orientation angle, and plasma treatment to fabricate the composites using the compression molding process. Taguchi analysis revealed that fiber orientation angle has the greatest influence among the three variables, with plasma treatment and weight fraction following in impact on tensile strength. The composite that exhibited the highest tensile strength was determined to have a weight fraction of 10%, a fiber orientation angle of 90°, and a plasma treatment period of 5 min. This combination yielded a strength of 30.351 MPa. The analysis of the interaction between any two factors was done using contour plots. In order to compare the experimental tensile strength values with the anticipated values derived from the regression equation, regression analysis was carried out.Highlights Composites were made up of recycled HDPE (rHDPE) from plastic bottles using a compression molding technique. The Taguchi method is applied to achieve an experimental design employing an L4 orthogonal array. Contour plot analysis is conducted to identify points of minimum and maximum responses, as anticipated from the results. Tensile strength was optimized to a maximum of 30.351 MPa.
