“…It could increase the interfacial polarization of the composite 39,40 . In addition, decreasing of the bonding between matrix and SiO 2 particles could contribute to motion of molecular chains and thus to increase the steering polarization and orientational polarization to some extend 41 . The factors could lead to the increase of dielectric constant of composites with high amount of SiO 2 particles.…”

In this work, Phthalonitrile containing benzoxazine (BA-ph) and Bisphenol A based cyanate ester (CE) were chosen as the matrix resin. Various amount of nano-SiO 2 was incorporated into BA-ph/CE and their glass fiber-reinforced composite laminates were fabricated. Curing reaction and processability of BA-ph/CE/SiO 2 blends were studied by differential scanning calorimetry and dynamic rheological analysis. Results showed that BA-ph and CE exhibited good processability and curing reaction of BA-ph/CE was not obviously affected by SiO 2. Scanning electron microscope images of the composites showed that SiO 2 particles were well dispersed in BA-ph/CE matrix. Moreover, SiO 2 could act as physical crosslinking points and diluent in matrix as well as between the glass fibers to improve the mechanical properties of composite laminates. As the results of dynamic mechanical analysis and thermogravimetry analysis, composite laminates possessed satisfactory T g and good thermal stability. With incorporation SiO 2 particles into matrix resin, dielectric constant and dielectric loss of BA-ph/CE/SiO 2 /GF composites were increased and showed frequency dependence.

Due to the inherent brittleness of thermosetting resins, pure thermosetting resins were hardly used as structural, substrate, or functional materials. In order to improve the brittleness of thermosetting resins, continuous fiber, nanoparticles were widely applied to reinforce the thermosetting resins to fabricate composites with enhanced properties. 1-4 Compared with that of traditional inorganic metal materials, fiber

“…The degree of crosslinking, curing process and mechanical properties, as coupling results of chemical reaction, heat transfer and product quality, play a decisive role in the comprehensive performance of the composites [9]. Some researches on the curing process and mechanical properties of the laminated composites are mainly focused on the curing kinetics and the stacking methods of the prepregs, respectively, which are not only the key to the success of curing process, but also are the guarantee of products quality [10,11].…”

In this study, the nonisothermal differential scanning calorimetry (DSC) was carried out to evaluate the curing reaction of fiber/epoxy laminates. The optimal curing process of the prepreg was obtained by T-β extrapolation method and n th -order reaction curing kinetic equation. The bending strength, impact strength and thermodynamic properties of the composite laminates with different ply orientations were investigated, respectively. The results show that the apparent activation energy and the reaction order of the prepregs are 82.89 kJ/mol and 0.92, respectively. The curing process of carbon fiber/epoxy resin prepreg is 130 ℃ /60min + 160 ℃/30 min. The bending strength of [0]10 laminate is 1948.3 MPa, which is 11.8 times higher than that of [+45/-45]5s laminate, and 96.4% higher than that of [0/90]5s laminate. The impact strength of [0]10 laminate is higher than that of [+45/-45]5s and [0/90]5s laminates. The glass transition temperature (Tg) of the laminates is 142~146 ℃, and the loss factor of [0]10 laminate is significantly higher than that of [+45/-45]5s and [0/90]5s laminates. This research provides a theoretical basis for the further application of prepregs to fiber composite materials.

The current research work presents a novel nonionic curing agent (AEDA) synthesized by utilizing ethylene glycol diglycidyl ether (EGDE), 3,4‐dimethoxyaniline (DI), and triethylenetetramine (TETA). Infrared spectroscopy and nuclear magnetic resonance spectroscopy were used to characterize the structure of AEDA curing agent. Non‐isothermal scanning calorimetry was used to determine the activation energy and curing conditions of epoxy resin in the curing process. An impact testing machine, a tensile testing machine and a scanning electron microscope (SEM) were used to analyze the impact strength, tensile strength, bending strength, and micromorphology of the AEDA/E‐51 system with different mass ratios. The results show that AEDA is an effective high‐temperature curing agent. For the AEDA/E‐51 system with the optimal mass ratio of 10:100, the best curing temperature is 92.15°C, and the post‐curing temperature is 135.65°C. Furthermore, the apparent activation energy (Ea) of 1670 J/mol, the pre‐exponential factor (A) of 3.7 × 10−4, and the reaction series (n) value of 0.76 are obtained for the AEDA/E‐51 system. The impact strength of AEDA/E‐51 epoxy resin polymer is 7.82 kJ/m2, tensile strength is 14.2 MPa, and bending strength is 18.92 MPa. The micromorphological results of the AEDA/E‐51 system are consistent with the results of DSC test and mechanical properties test. Hence, this study provides theoretical support for the practical applications of AEDA as curing agent.
