“…The limited information on epoxy composites might be attributed to the relatively higher cost as compared to the other polymer resins. However, for high-performance applications, epoxy provides good adhesion to the reinforcing filler and improved enhanced mechanical properties in association with its low moisture content, less shrinkage upon curing, and easy room temperature processing [ 64 ].…”

Kenaf (Hibiscus cannabinus L.) is one of the most investigated and industrially applied natural fibers for polymer composite reinforcement. However, relatively limited information is available regarding its epoxy composites. In this work, both thermal and chemical properties were, for the first time, determined in kenaf fiber reinforced epoxy matrix composites. Through XRD analysis, a microfibrillar angle of 7.1° and crystallinity index of 44.3% was obtained. The FTIR analysis showed the functional groups normally found for natural lignocellulosic fibers. TMA analysis of the composites with 10 vol% and 20 vol% of kenaf fibers disclosed a higher coefficient of thermal expansion. The TG/DTG results of the epoxy composites revealed enhanced thermal stability when compared to plain epoxy. The DSC results corroborated the results obtained by TGA, which indicated a higher mass loss in the first stage for kenaf when compared to its composites. These results might contribute to kenaf fiber composite applications requiring superior performance.

“…The development of the aerospace, automotive, and construction industries leads to the increase in the requirements for polymer binders for composite materials. In order to improve physico-mechanical and thermophysical properties, epoxy binders are modified with thermoplastic rigid-chain polymers (TPs) [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 ]. Currently, a large number of publications are devoted to the structure and properties of cured compounds with given compositions [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 ].…”

“…According to [ 7 , 12 , 15 ], mixtures of an epoxy oligomer (EO) with rigid-chain thermoplastics such as polysulfone and polyethersulfone (which have similar molecular structures) are characterized by PD of amorphous separation with upper and lower critical solution temperatures, respectively.…”

Phase Equilibrium, Morphology, and Physico-Mechanics in Epoxy–Thermoplastic Mixtures with Upper and Lower Critical Solution Temperatures

The mutual solubility of epoxy oligomer with polysulfone (PSU) and polyethersulfone (PES) was studied by optical interferometry. Additionally, phase diagrams (PDs) were plotted and their evolution during the curing process was shown. The phase structures of modified hardened systems, as well as their tensile strengths, elastic moduli, and crack resistance, have been studied by scanning electron microscopy and physico-mechanical techniques. The effect of initial components’ mutual solubility on the phase structure and, subsequently, on the physico-mechanical properties of the composite material is shown. Differences in the structure and properties of the cured modified compositions depending on the type of PD (with Upper Critical Solution Temperature (UCST) for PSU and Lower Critical Solution Temperature (LCST) for PES) of the initial components are shown.

“…[8][9][10] A practical approach to toughen epoxy resins is to use thermoplastics with high glass transition temperature, excellent thermal stability and toughness, such as polysulfone (PSF), [11][12][13] poly(ether sulfone) (PES), [14][15][16] polyimides (PI) [17][18][19] and poly(ether imides) (PEI). [20][21][22] PEI with excellent mechanical properties can effectively improve the toughness of epoxy resin without sacricing other properties of epoxy resin and has been widely used as the modier of epoxy resin. 23,24 For a typical thermoplastics-modied system, phase separation will occur during the curing reaction of epoxy resin and the blend separates into two phases.…”
