Shielding performances of short carbon fibers and tungsten particles reinforced benzoxazine resin matrix composites

This present investigation reports, for the first time, the properties of the polybenzoxazine bio-based furfurylamine reinforced using the hybrid short carbon fibers and tungsten particles. The results revealed good compatibility between the matrix and the filers using scanning electron microscopy, due to the use of the silane treatment that led to enhanced interfacial bonding. In addition, the mechanical data disclosed that the bending and impact values were respectively increased to 210 MPa and 9 KJ/m2 for the composites containing 20%wt of the short carbon fibers and 20%wt tungsten particles. The hybrid composite shielding properties were evaluated using the cobalt-60 as an irradiation source, and the nuclear results depicted that the half-value length and the tenth-value length were increased as compared to those of the pure polymers. Based on the thermal stability studies, the reinforced hybrid composites also …

Polymer composites based Epoxy-WB and WB2: Gamma-rays impact on structure, thermal degradation, and mechanical behavior

High performance polymer composites are essential materials in nuclear applications where many components can receive high ionizing rays doses such as gamma-rays. In this work, two composites named E51WB and E51WB(2) based on epoxy (E51) and tungsten borides (WB and WB2) were manufactured at room temperature and then exposed to gammarays doses up to 2000 KGy. The goal of this study was to investigate and compare the impact of gamma-rays on the chemical structure, mechanical and thermal properties of E51WB and E51WB(2) composites using FTIR, SEM, TGA and tensile tests. As the results, the char yield (Yc) for E51WB gradually increased from 40 to 46% at 0, 1000 and 1500 KGy, then slightly drop to 44% at 2000 KGy. The E51WB sample displayed the strain value of 2.3% at 0 KGy, and it increased to 4.7 and 5 % at 1000 and 1500 KGy, respectively, while at 2000 KGy it decreased to …

High performance green composite from vanillin-based benzoxazine containing phthalonitrile and silane surface modified basalt fibers

Benzoxazine containing phthalonitrile, as one of the most advanced high performance thermosetting resin, has gained a lot of attention in the last decades. Indeed, the combination of the thermally activated ring-opening polymerization of the benzoxazine and the cyano addition reaction of the phthalonitrile allows the development of robust polymeric networks. Following this path, a renewable natural resource, vanillin, was used to develop a new benzoxazine containing phthalonitrile thermosetting system. The newly developed monomers present the advantage of a simple synthesis process along with an autocatalytic polymerization mechanism. The molecular structures of the synthesized monomers were characterized by Fourier transform infrared spectroscopy (FTIR) and proton nuclear magnetic resonance spectroscopy (1H NMR). The curing behavior was assessed by differential scanning calorimetry (DSC …

Development of highly performant hybrid materials based on phthalonitrile resin for a simultaneous ballistic and nuclear shielding protection

In this study, a new high-performance hybrid material was designed targeting an efficient ballistic and nuclear shielding protection. To achieve this goal, a typical highly performant thermosetting resin, namely the phthalonitrile (PN) resin, was reinforced with Kevlar fibers (KF-29), as continuous phase, and erbium oxide (Er2O3) nanoparticles, as discontinuous phase. The reinforcing phases underwent a silane surface modification to create a fully connected network aiming an improved stress transfer between the constituents. The mechanical investigations through tensile and bending testing confirmed the positive effect of the addition of an increasing amount (up to 20 wt%) of the Er2O3 nanoparticles. The hybrids also provided excellent gamma rays shielding performances with a screening ratio of about 33% for a 3 cm thick sample. In the meantime, the ballistic tests evaluated under the National Institute of Justice …

As the huge demands for advanced engineering materials with specific properties, this study aimed to fabricate novel lightweight materials possessing ameliorated characteristics. The novel hybrid composites were prepared by reinforcing both the bisphenol-A based dicyanate ester and benzoxazine (DCBA/BA-a) resin blends using silane-treated short glass/basalt hybrid fibers through a compression molding technique, and then experimentally characterised. Results from the mechanical and thermal analyses revealed that the mechanical and thermal parameters were highly improved upon increasing the reinforcing phases’ amount. The shielding evaluations disclosed that the integration of hybrid fibers helped the DCBA/BA-a blend to possess excellent nuclear shielding properties.

Study of gamma‐ray radiation effects on series of bisphthalonitrile resins: Thermomechanical, mechanical, and thermal properties

The bisphthalonitrile (PN) thermosets series (poly(Baph), poly(Bafph), and poly(Bzph)) were prepared and subjected to 100 and 500 kGy γ‐ray irradiation dose from cobalt‐60 (60Co) as a source. The main objective of this present study was to investigate the effects of gamma irradiation on the chemical structure, thermomechanical, mechanical, and thermal stabilities, which were studied by using a Fourier transform infrared (FTIR), dynamic mechanical analysis, bending test, and thermogravimetric analysis, respectively. The PN resins characteristics bands, namely, nitrile, triazine ring, and phthalocyanine, were not affected on γ‐ray irradiation. However, remarkable changes were observed in the chemical structures of benzene, alkyl and CF3, which indeed slightly declined the thermal stabilities, thermomechanical and flexural properties. The decrease in properties could be ascribed to the scission of molecular …

Effects of accelerated weathering on the mechanical properties of hemp fibre/polybenzoxazine based green composites

In the current study, three different kinds of hemp fibre treated polybenzoxazine composites were exposed to accelerated weathering at 30 °C and 80% relative humidity (RH), till the saturated moisture uptake. The tensile, flexural, and impact properties of saturated samples were evaluated and results were compared with the unconditioned samples. The silane treated hemp fibre (STHF) composites showed the lowest decline in the properties. Afterwards, the STHF composites were exposed to various accelerated weathering conditions, in the range of 25–35 °C and 40–80% RH. Moisture uptake was slightly increased and tensile and flexural properties were gradually decreased as the exposure temperature and RH were increased. Highest decline was observed in the samples exposed at 35 °C and 80% RH. Furthermore, the slightly higher impact values were observed for the exposed composites. The …

Studies on the curing behavior, thermal, and mechanical properties of epoxy resin‐co‐amine‐functionalized lead phthalocyanine

A high performance copolymer was prepared by using epoxy (EP) resin as matrix and 3,10,17,24‐tetra‐aminoethoxy lead phthalocyanine (APbPc) as additive with dicyandiamide as curing agent. Fourier‐transform infrared spectroscopy, dynamic mechanical analysis (DMA), differential scanning calorimetric analysis (DSC), and thermogravimetric analysis (TGA) were used to study the curing behavior, curing kinetics, dynamic mechanical properties, impact and tensile strength, and thermal stability of EP/APbPc blends. The experimental results show that APbPc, as a synergistic curing agent, can effectively reduce the curing temperature of epoxy resin. The curing kinetics of the copolymer was investigated by non‐isothermal DSC to determine kinetic data and measurement of the activation energy. DMA, impact, and tensile strength tests proved that phthalocyanine can significantly improve the toughness and stiffness …
