Summary: This study evaluated the effects of nanofiller content and exposure time on the durability of graphene-modified epoxy vinyl resin in a simulated ordinary concrete environment. The results showed that the addition of 0.3 wt% graphene improved the mechanical properties of the resin samples significantly. A novel multi-stage compressive constitutive model was proposed to describe the stress-strain response of polymer-based composites. Additionally, the durability of the graphene-modified resin samples was enhanced after exposure to the simulated concrete environment.

Summary: This study investigated the effect of gamma irradiation on the properties of epoxy composites reinforced with carbon-doped boron nitride (BCN). The results showed that modified BCN/epoxy composites exhibited excellent mechanical and thermal properties before and after irradiation. The improved performance was attributed to the compatibility between modified BCN and epoxy, as well as the protective barrier provided by BN.

Summary: In this study, silicone polymer (PSOL)/carbon fiber (CF)/epoxy (EP) composites were prepared by adding PSOL as interfacial modifiers in CF/EP composites. The mechanical and dynamic mechanical properties of the composites were investigated, and the optimal content of PSOL modification was determined. The addition of PSOL improved the interfacial bonding ability between CF and the matrix, resulting in increased interlaminar shear strength, tensile strength, elongation at break, and flexural strength of the PSOL/CF/EP composites by 23.28%, 18.49%, 38.45%, and 11.23%, respectively. Furthermore, the thermal stability of the composite was preserved after the PSOL modification.

Summary: The research indicates that the liquid oxygen compatibility of epoxy resin and CF-composites can be improved by preparing DOPO-PGE. The mechanism of DOPO-PGE mainly involves capturing highly active radicals to terminate exothermic reactions. While CF-composites show better liquid oxygen compatibility than epoxy resin, prolonged liquid oxygen immersion can deteriorate their compatibility.

Summary: This paper proposes an equivalent linearization method considering higher order statistics for the geometrically nonlinear random vibration problems of complex structures, based on nonlinear reduced order modeling techniques. The nonlinear reduced order models are constructed using commercial finite element codes, and an improvement to the stiffness coefficients determination is achieved through the equivalence relation, resulting in a significant reduction in computational cost and eliminating the need for additional commercial finite element codes. The nonlinear terms are regulated to introduce higher order statistics into the equations of motion, and a linearized system is used to predict the random response of the original nonlinear system, significantly increasing computational efficiency.

Summary: This paper proposes a new label form, called importance filtered soft label, which maximizes the nuclear norm of a soft label matrix to filter noisy probability values and produce a more reliable form of importance filtered soft label. Several prevalent label-induced losses are reformulated using this label form in a probability-weighted manner to optimize them more correctly and alleviate the negative adaptation problem.
