“…Though these fibers have had a very good compatibility with all set of resins, it has its own set of problems like poor recyclability, not environmentally (non bio-degradable) cooperative, like many other imperative harmful problems to the eco system. Furthermore the overall high cost of the synthetic fiber gives the alarming signal to the many manufacturing units when set to sell the product in customer end in due course of time [7][8][9]. From an environmental standpoint, it would be quite interesting, if natural fibers could be used instead of glass fibers as reinforcement in various structural elements.…”

A customary ratio of vinyl ester (VER) and Polyurethane (PU) resin were chosen as the matrix material (blend) to attain the complete Interpenetrating Polymer Networks (IPN). In this course of research, the mechanical properties of the Banana fiber reinforced IPN (blend) matrix were thoroughly investigated by precisely varying the loading of polyurethane into vinylester as 0%, 10%, 20%, 30%, 40%, 50% PU respectively. Besides that, the fabricated banana fiber reinforced polyurethane loaded IPN laminate were experimentally investigated in order to characterize the strength of the laminate as per the ASTM standards. The test results exhibit that, strain rate of the laminate increases to many folds as compared (Tensile 0% PU -0.45% & 50% PU -3.1%, Flexural 0% PU -0.62% & 50% PU -3.73%) with the neat vinylester resin based banana fiber reinforced laminate. In addition to that, it also increases the impact strength and moisture resistance (Impact 0% PU -2.93 kJ/m 2 & 50% PU -8.01 kJ/m 2 , Moisture 0% PU -0.42% & 50% PU -0.96%) of the IPN laminate considerably depends upon the loading of the polyurethane. As well as to validate further, the fractured surfaces were assessed through Scanning Electron Microscope (SEM). Finally the experimental values were also cross-verified by analytical simulation software by using ANSYS. Finally, the cross-verification proved that both the results of experimental and FEA analysis of the material were in good co-relation with each other.

“…Due to the lightweight and improved viscoelastic features of interpenetrating polymer networks, they can be employed for applications such as glass fibre reinforced polymer pipes, bridges and storage tanks. [17][18][19] Polyhydroxyurethane networks were produced through radical polymerization of hydroxyurethane methacrylate prepolymers using an isocyanate-free method. The process is performed in three steps.…”

“…Furthermore, the inclusion of PU can remarkably reduce the flexural ratio of stress to strain but adversely increases the strain value. Due to the lightweight and improved viscoelastic features of interpenetrating polymer networks, they can be employed for applications such as glass fibre reinforced polymer pipes, bridges and storage tanks 17–19 . Polyhydroxyurethane networks were produced through radical polymerization of hydroxyurethane methacrylate prepolymers using an isocyanate‐free method.…”

In this paper, we report the production of a mixture of urethane modified vinyl ester resin through the non‐isocyanate polyurethane method without using the poisonous material phosgene. Initially, treatment of 2‐((4‐((oxirane‐2‐yl)methoxy)butoxy)methyl)oxirane with methacrylic acid produces a mixture of 3‐(((oxirane‐2‐yl)methoxy)butoxy)‐2‐hydroxypropyl methacrylate and its non‐methacrylated and dimethacrylated analogues (here simply termed OMBM). Then, cyclic carbonate of the as‐prepared compound is obtained through treatment of OMBM and carbon dioxide gas applying different catalysts. The reaction of synthesized cyclic carbonate with various diamines produces isocyanate‐free urethane modified vinyl ester resin. Afterwards, the corresponding products were cured with varying percentages of vinyl ester resins, applying benzoyl peroxide and N,N‐dimethyl aniline as initiator and accelerator, respectively, to enhance the mechanical characteristics of the vinyl ester resins such as tensile strength and elongation. Various characterization methods such as Fourier transform IR, NMR, swelling and tensile tests are conducted to confirm the success of the reactions. © 2022 Society of Industrial Chemistry.
