“…The jute fibers are abundant, low in cost, and nonabrasive to the tooling during processing and most importantly, they are environment friendly, that is, they sequester atmospheric carbon dioxide during their growth period. The studies on jute reinforced thermoset based (eg, unsaturated polyester, epoxy, vinyl ester, and phenolic) composites have been carried out by various authors as the processing of such composites is easier due to effective impregnation of the fibers by the resins in comparison with thermoplastic matrix composites. Although thermoset composites possess superior mechanical properties, except toughness, they are not recyclable and pose potential threat to the environment due to their non‐recyclability.…”

This work presents the effect of chemical treatment of short jute fibers using alkali, potassium permanganate, and silane treatment on the mechanical properties of jute‐polypropylene (PP) composites. The chemically treated jute fibers were compounded at 30% weight fraction with PP granules in twin‐screw extruder, and the composite pellets were later injection molded to obtain the specimens for the study. The optimum parameters for the respective chemical treatments used in this study were followed as per the literature. The effectiveness of the chemical treatment carried out was studied using Fourier transform infrared spectroscopy and scanning electron microscopy. The mechanical characterization comprising tensile test, flexural test, impact test, and microhardness test were conducted on jute‐PP composites. In addition, the effect of chemical treatment on the water absorption kinetics of the jute‐PP composites was studied. The diffusion coefficient of the jute‐PP composite was determined using the approximate solution of Fick's model. The silane‐treated jute‐PP composites show an increase in tensile strength, tensile modulus, and flexural modulus by nearly 6%, 22%, and 20%, respectively, compared to untreated jute‐PP composite. The moisture absorption study reveals that the silane‐treated jute‐PP composite is the most effective.

“…Higher tan δ and curve areas signify increased molecular mobility, indicating improved damping effects of the material. 40,41 The resin in PMBLR217/GF is a non-crystalline thermoplastic resin, featuring a non-crosslinked linear structure that allows the polymer chains to undergo elastic deformation and dissipate applied stress. Conversely, the 3D crosslinked network structure of the resin in epoxy/GF inhibits such variations.…”

In recent years, the growing environmental awareness has prompted increased attention towards the substitution of nonrecyclable thermosetting epoxy resin composite materials with recyclable thermoplastic composite materials. The objective of this study is to utilize a laboratory‐made polymethyl methacrylate (PMMA)/methyl methacrylate (MMA) binary liquid resin (PMBLR) to prepare thermoplastic resin/glass fiber (GF) composite materials using the vacuum‐assisted perfusion method. These composites are then compared with GF‐reinforced thermosetting epoxy resin composites. The investigation reveals a significant influence of benzoyl peroxide (BPO) content on the mechanical properties of pure MMA and PMBLR casting resins, which also incorporate N‐methyl‐N‐((1‐methyl‐1H‐indol‐3‐yl) methyl) aniline (DMA) as redox composite initiators. The optimal mechanical properties for both types of casting resins are achieved at a DMA:BPO:MMA ratio of 0.5:1.2:100. Additionally, at a PMMA concentration of 24 wt% in PMBLR under this specific initiator ratio, the composites demonstrate the most desirable properties. Furthermore, a comparative analysis of PMBLR/GF composites and epoxy/GF composites indicates that the former exhibit superior 90° tensile strength, bending strength, and short beam shear strength. The fracture morphology analysis highlights discernible micro‐ductile fracture characteristics in PMBLR/GF composites, distinguishing them from epoxy/GF composites. Dynamic thermomechanical analysis (DMA) results further reveal a higher storage modulus and loss factor in PMBLR/GF composites when compared to epoxy/GF composites.Highlights Glass fiber‐reinforced composites were fabricated at ambient temperature. A degradable PMMA/MMA binary thermoplastic resin (PMBLR) was developed as a replacement for non‐degradable epoxy. PMBLR composites exhibit enhanced strength compared to epoxy: tensile (+18.8%), bending (+27.4%), and short beam shear (+34.3%).

“…This results in improved dimensional stability (less warpage), low cure shrinkage, and acceptable surface smoothness to the resultant composites. In previous work, 23 –26 attempts on using unsaturated polyester–polyurethane (UP/PU) hybrid networks as matrix resin for producing jute composite laminates have not received much attention necessitating a detailed examination of its suitability as an alternative to conventionally used UP for making dimensionally stable composite building products.…”

Hybrid networks (unsaturated polyester–polyurethane (UP/PU)) of UP resin and PU prepolymer were synthesized and characterized for their phase miscibility with the help of Fourier transform infrared spectroscopy, differential scanning calorimetry, dynamic mechanical analysis (DMA), and atomic force microscopy. The existence of hydrogen bonded –NH groups, broadened glass transition region, and reduced phase domains evidenced the formation of intermixed phase when compared with the parent UP. The optimum mechanical properties of UP/PU hybrid networks were observed at ∼5 wt% PU content. The composites made from treated jute fibers and UP/PU hybrid networks were evaluated for their physico-mechanical properties. DMA curves showed that UP/PU matrix composites had ∼20% higher storage modulus and ∼17% lower tan δ than the polyester matrix composites. The tensile and flexural strengths of these composites were increased by ∼13% and ∼40%, respectively. During accelerated aging, the UP/PU matrix composites retained ∼15% more tensile strength than the polyester matrix composites. Fractographic evidence, such as resin adherence onto the pullout fiber surface, fiber breakage, and adequate adhesion between the jute fibers and the resin, supported the superior properties of UP/PU matrix composites to polyester matrix composites.
