Epoxy Resin System

In this paper a tensile characteristics of filament-wound glass fiber-aramid fiber/epoxy resins hybrid composites and glass fiber-two carbons fibers/epoxy resins hybrid composites are presented. Basic terms about hybride composite materials (origin, reasons for manufacturing, advantages, definitions, levels of hybridization, modes of classifications, types, categorization, and possible interactions between constituents) and used reinforcements and matrices are described. For a manufacturing of NOL rings four reinforcements (glass fiber, polyamide aromatic fiber and two carbon fibers) and two matrices (high and moderate temperature curing epoxy resin system) are used. Based on experimentally obtained results, it is concluded that hybride composite material consisting of carbon fiber T800 (67 % vol) and glass fiber GR600 (33 % vol) impregnated with epoxy resin system L20 has the highest both the tensile strength value and the specific tensile strength value. The two lowest values of both tensile strength and the specific tensile strength have hybrid material containing aramide fiber K49 (33 % vol) and glass fiber GR600 (67 % vol) and epoxy resin system 0164 and hybrid NOL ring with wound carbon fiber T300 (33 % vol) and glass fiber GR600 (67 % vol) impregnated with the same epoxy resin system. This investigation pointed out that increasing the volume content of aramide fiberK49, carbon fiber T300 and carbon fiber T800 in appropriate hybrid composites with glass fiber GR600 increases both the tensile strength value and the specific tensile strength value and decrease the density value, no matter the used epoxy resin system.

The synthesis of Lignin Base Epoxy Resin was based on industrial alkali lignin, and lignin-based epoxy resin curing characteristics were analyzed using the thermal weight loss technology under the oxygen atmosphere conditions. In light of the infra-red analysis of raw materials, the curing reaction kinetic parameters of lignin-based epoxy resin system were calculated using the Kissinger-Crane and Flynn-Wall-Ozawa method, and the curing reaction kinetics model of lignin-based epoxy resin system was established. The results showed that the kinetic parameters obtained using two methods were approximate, which validated that the curing reaction was consistent with the principle of the first-order reaction model. Initial curing temperature Ti0=454.88 K, curing temperature Tp0=507.55 K, and terminal temperature Tf0=598.77 K of lignin-based epoxy resin system were obtained when the extrapolation method was applied.

In this study, the curing kinetics of the phenolic amine/epoxy resin system were investigated by nonisothermal differential scanning calorimetry (DSC). The model-free isoconversional method of Ozawa–Flynn–Wall reveals a dependence of Eα (activation energy) on conversion (α), which interprets the autocatalytic curing reaction mechanism of the phenolic amine/epoxy resin system. Studies on the effects of nano-SiO2 particles on the tensile properties and tensile fracture face morphology of nanocomposites show that the uniform dispersion of SiO2 nanoparticles plays an important role in promoting the tensile performance of nanocomposites. Additionally, increases of 184.1% and 217.2% were achieved by adding 1.5% weight parts of nano-SiO2 in composites for the tensile strength and tensile modulus, respectively.
