Summary: The flexural and flexural fatigue reliability of glass fabric/epoxy composites used in anti-roll bars were investigated under different temperature conditions. It was found that the flexural strength and fatigue strength of the composites improved at sub-zero temperatures, due to the accumulation of residual stresses, an increase in glass transition temperature, and an increase in chain stiffness in the epoxy matrix.

Summary: TBDCs are a new class of composite materials that combine in-plane isotropy, high strength and stiffness, and enhanced manufacturability. This study develops an experimental and analytical framework that identifies key properties and predicts the performance of TBDCs. Fractography and a parametric study are used to understand the damage mechanisms and the critical effects of tape thickness and fracture toughness. The material's performance is compared to similar TBDCs from the literature, showing significant strength and stiffness increases.

Summary: The excellent properties of carbon nanotubes allow for high thermal and electrical conductivity, but the weak coupling between them leads to performance below expectations. This study introduces polypyrrole (PPy) to improve both electrical and thermal conductivity of carbon nanotube-based materials, providing new design ideas for advanced electronic devices.

Summary: This paper presents a study on six single-stringer specimens manufactured using the card-sliding technique with non-crimp fabrics and adopting a Double-Double (DD) stacking sequence. The specimens were tested under compression loading conditions to investigate post-buckling and failure in aerospace structures. Experimental results and numerical simulations were compared to analyze the behavior and failure modes of the specimens. The study found promising evidence of a viable solution to optimize aeronautical structures and enhance resistance to skin-stringer separation, particularly with the use of tapered flanges.

Summary: The effect of linear heat input on the interface and mechanical properties of steel/CFRP joint was investigated. Adequate linear heat input promotes the spread of resin on the steel surface and the chemical connection between steel and CFRP. However, excessive linear heat input leads to the generation of decomposing pores in the resin and decreases the performance of the steel/CFRP joint.

Summary: In this paper, a multilevel Long Short-Term Memory (LSTM) neural network combined with ultrasonic detection is proposed to identify lamination defects in carbon fiber composites. Through simulating ultrasonic transmission and incorporating multiple levels of learning, the accuracy and convergence of the traditional LSTM are significantly enhanced. Compared to traditional ultrasonic detection methods, this approach only requires a one-to-one transmission and reception mode, offering a time-saving and cost-effective solution.

Summary: The main objective of this article is to compare the Eurocode approach with experimental data and provide suggestions for its application for prestressed FRP reinforcement. Through analyzing the results of over 300 and 100 specimens, parameters describing the type and surface of pretensioned FRP reinforcement are derived based on the Eurocode method. The influence of shear reinforcement and the type of pretensioned reinforcement release is also taken into account. The results show that the Eurocode approach, with coefficients proposed for different FRP reinforcements, provides the best prediction for the experimental transfer, flexural bond, and anchorage length results when compared to North American design codes for FRP reinforcement and the Eurocode for steel strands.

Summary: This study investigates the effect of non-uniform fibre distribution (NUFD) on the mechanical properties of pultruded glass fibre-reinforced polymer (GFRP) box section profiles. The results show that corner NUFD has a greater impact on the local buckling capacity than flange NUFD. Additionally, a linear relationship between the rotational restraint coefficient and corner fibre volume fraction is observed.

Summary: This paper introduces the HF-FEM and HTS-FEM methods based on 3D polyhedron-octree for analyzing heat conduction and thermal stresses in particle-reinforced composites. The proposed methods partition the materials into polyhedron-octree elements and use hammer integration to perform integrals. A technique for constructing the heat flux function for polyhedral elements is also presented. The effectiveness of these methods is demonstrated through numerical examples comparing them to traditional finite element methods.
