“…Parmar et al 10 reported that the three-component IPN matrix based glass fiber-reinforced composites made with the vinyl ester of an epoxy novolac resin, diglycidyl ether of bisphenol-A and MMA. They found that it is resistant to the chemicals and has better thermal, mechanical properties than neat resin.…”

Interpenetrating polymer networks of vinyl ester (VE) resin and polyurethane (PU) were synthesized using blend ratio of 93:7(w/w). Two sets of nanocomposites based on i) pure vinyl ester and ii)VE/PU IPN(93VE), were prepared with organically modified silica nanoparticle (OMS) as filler by 1, 2, 3 and 5% weight of the matrix resin. All the nanocomposites were characterized in terms of mechanical and thermomechanical properties.VE/silica nanocomposite with 2% filler (VES2) showed improvement in ultimate tensile strength by 83.5% and toughness by 42% compared to that of VE resin itself. The IPN based nanocomposite, 93VES2, exhibited 31.14%, 10.8% and 18%greater tensile strength, Young’s modulus and toughness respectively in comparison to that of the base 93VE IPN. IPN based nanocomposites were tougher than VE based nanocomposites. Storage modulus of nanocomposites was lower than that of 93VE and VE matrix system. Higher tanδmax of the 93VE/OMS nanocomposites than that of the 93VE matrix was indication of more elastic nature of the later. Smaller size of dispersed domains was found in SEM micrographs for IPN based nanocomposites than that in micrographs of VE based nanocomposites of corresponding composition.

“…Kissinger-Akahira-Sunose (KAS) method is an evaluation of the Arrhenius equation using differential method and it is independent of exact mechanism of thermal degradation. 33 It is an integral isoconversional method, which is based on the Murray and White approximation for temperature integral and is mentioned as equation (12). Integration of this equation within the initial boundary condition of α = 0 at T = T 0 gives equation (13).…”

“…9,10 Polyurethane is a class of very useful and versatile material and widely used for various applications. 11,12 Its unique acceptance throughout the world is due to the elasticity combined with the toughness and durability under adverse conditions of pH, temperature, humidity, etc. 13 In the past few decades, a considerable amount of work has been accomplished to improve the mechanical and thermal properties of vinyl ester resins.…”

“…The results showed a significant improvement in the mechanical and thermomechanical properties of the IPNs with respect to that of the pure major component. Jayant S. Parmar and coworkers (2004) 12 reported a work on three-component IPN matrix based glass fiber reinforced composites (GRC) made from the vinyl ester of an epoxy novolac resin, diglycidyl ether of bisphenol-A and MMA. These IPNs showed satisfactory resistance to chemical reagents, improved thermal stability and better mechanical properties than the pure VE.…”

Interpenetrating polymer networks based on vinyl ester resin and polyurethane were synthesized using different blend ratio, for example, 93:7, 90:10, and 80:20 (w/w). The samples were subjected to thermogravimetric analysis under non-isothermal conditions in presence of an inert atmosphere within the temperature range of 303–773K. Determination of distributed activation energy at various stages of degradation process and its implication in the reaction mechanism was investigated by using various isoconversional models and Kissinger’s model fitting approaches. It was observed that IPNs showed higher thermal stability and also possessed higher activation energy for degradation than pure VE in the selected range of temperature when heated at a specific rate.

An innovative manufacturing process for continuous fiber composites with the polymeric matrix made up of polypropylene and epoxy resin, as a model reactive low molecular weight component, was developed; variable process parameters give rise to different morphologies of matrix components surrounding the woven fabric reinforcement. Furthermore, the combination of both thermoplastic and thermosetting polymers permitted intimate fibers impregnation, typical of thermosetting matrix composites, with short process cycle time, which usually occurs in manufacturing process of thermoplastic matrix composites. Polypropylene (PP) films, glass fibers fabric, and epoxy resin film were used to produce flat composite through film‐stacking technique. The preparation process focused on control of both epoxy resin cure process and polypropylene melting. The process was able to induce the two matrix components to form either a planar (sandwich‐like) structure or a three‐dimensional (3D) network by means of controlling the process parameters such as pressure and heating rate. The strong enhancement of the mechanical properties (Young's modulus and tensile strength of the composites with the 3D structure were almost twice as high of those of the composites with sandwich‐like matrix structure) was due to the different microstructures produced by the interplanar flow of the thermoplastic polymer.
