“…Eventually, the temperature rises sharply and damage to the hybrid joint occurs. Thus, an empirical nonlinear model for the rise of self‐heating temperature of hybrid joints is developed based on the empirical nonlinear model for the growth of residual slip established by Xing et al, 46 as shown in Equation ().

T ((), N) goodbreak= {(\frac{(v_{e} - \frac{N}{N_{f}})}{\frac{N}{N_{f}} \times {k_{e}}^{\frac{1}{m_{e}}}})}^{- m_{e}},

where k e approximates the center of gravity of the stiffness curve, m e characterizes the slope of the second phase of the curve, and v e denotes a constant value; k e , m e , and v e are obtained by fitting the experimental data.…”

The self‐heating‐induced temperature rise in the adhesive layer under fatigue loading plays a significant role in influencing the fatigue behavior of riveted‐bonded hybrid joints in aluminum‐carbon fiber reinforced polymer composite structures. This study aims to investigate the impact of the self‐heating effect on the fatigue life of such hybrid joints. Experimental analysis was conducted to explore the interrelationships between temperature evolution and fatigue behavior at varying frequencies, adhesive thicknesses, and loading levels. Additionally, a theoretical model for predicting self‐heating temperature rise in hybrid joints with different parameters was developed. Results show that the self‐heating effect is notably affected by loading frequency, loading level, and adhesive thickness. The theoretical model accurately captures temperature variations and predicts critical frequencies for hybrid joints under different loading levels, which are identified as 10, 8, 3, and 1 Hz for loading levels of 35%, 40%, 50%, and 60%, respectively. Critical adhesive thicknesses ranging from 0.5 to 1 mm were also determined. Furthermore, the study predicts the fatigue life at specific self‐heating temperatures with an average error within 4%, offering valuable theoretical insights for evaluating the fatigue safety performance of hybrid joints and facilitating optimization strategies.Highlights The interrelationship between the self‐heating effect and fatigue behavior was revealed. Quantitative influences of main process parameters on the self‐heating effect were discussed. A self‐heating temperature rise model considering process parameters was developed. The critical frequency and adhesive thickness of the hybrid joint were determined.

Polymer composite researchers have extensively explored the influences of fiber orientation, volume fraction, type, length, as well as the impacts of matrix type, matrix/reinforcement interface, fibers hybridization, and nanoparticle incorporation on the mechanical behaviors of fiber-reinforced composite materials. The impacts of tailored fiber architectures on the mechanical characteristics of bulk polymeric-based composites, on the other hand, have not been investigated. The purpose of this research is to determine the effect of fiber arrangement on the mechanical characteristics of glass fiber-reinforced polymeric materials (GFRP). Unreinforced (UR) polyester, surface reinforced arranged (SRA) composites and bulk reinforced arranged (BRA) composites were fabricated. Characterizations have been performed using scanning electron microscope rotating bending fatigue machine and a universal testing machine. Results demonstrate that SRA’s lifespan after being exposed to bending fatigue has increased significantly with respect to UR and BRA samples. Average fatigue life for SRA samples is 61 times longer than the life of BRA samples at 56 MPa bending stress. Furthermore, a Weibull distribution function with shape parameter and scale parameter was implemented to analyze the fatigue life dataset statistically. The introduction of SRA novel design has promising results for cost reduction as well as quality improvement.

This paper presents a comprehensive study of the fabrication and joining mechanisms of carbon fiber reinforced polymer (CFRP) composites. The CFRP composites were fabricated by hand lay‐up and vacuum bagging methods. In order to improve the efficiency of the CFRP‐CFRP and CFRP‐AL 7075‐T651 joints, laminates with varying overlap lengths of 25 and 60 mm single lap joints were prepared in both multi‐riveted and hybrid bonded/riveted joint configurations. Due to the epoxy compatibility of CFRP‐CFRP joints, riveted/bonded hybrid joints (HJs) showed superior improvements compared to riveted joints for both material combinations at 25 and 60 mm overlap lengths. Non‐epoxy compatible surfaces of CFRP‐AL 7075‐T651 specimens performed similarly to riveted joints in hybrid configurations. The use of epoxy compatible surfaces was found to increase the joint strength in CFRP‐CFRP single lap hybrid joints in proportion to the increase in overlap length. Ansys non‐linear analysis and experimental results were complementary. The new improvements in joint efficiency of CFRP composites create a wide range of structural applications considering the increasing lifetime of the components and joints.Highlights Riveting of composites have negative impact on joint strentgh. Hybrid joints using a combination of rivets and adhesives can increase the load bearing capacity. Tensile performance strategy of joint in composites can be improved by diversification of joint combinations.
