In this study, the binding of amine‐based hyperbranched macromolecular polyethyleneimine (PEI) to diatomite (DE) was carried out by using the silane coupling agent KH560 (PEI‐KH560‐DE). Fourier infrared spectroscopy, scanning electron microscopy were used to characterize the structure of the modified DE. Then, the composites were prepared using PEI‐KH560‐DE as the filler in the epoxy resin matrix and then cured with dimethylimidazole. The cured composites were tested for impact resistance, flexural properties, and tensile properties, and then subjected to DSC. The experimental results showed that when different proportions of diatomite or modified diatomite were added to the epoxy resin matrix, the strength and toughness of the composites could be significantly enhanced. When the content of PEI‐KH560‐DE was 15 wt%, the impact strength of the composites reached the maximum value of 5.39 kJ/m2, which was 156.67% higher than that of the pure epoxy resin (2.10 kJ/m2). The tensile strength was also improved from 16.38 MPa of the pure epoxy resin to 26.55 MPa, corresponding to an increase of 62.09%. With the addition of modified diatomite, the Tdmax and char yield of the composites were significantly enhanced, indicating that the addition of diatomite can enhance the heat resistance and thermal stability of the composites. The curing kinetics study showed that the addition of PEI‐KH560‐DE can significantly reduce the apparent activation energy required for the curing reaction of epoxy resin probably due to the presence of amine group in PEI, which plays a role in promoting the curing behavior.Highlights Amine groups and flexible chain segments were introduced into diatomite. Mechanism of polyethyleneimine‐modified diatomite was investigated. Improved mechanical and thermal properties of PEI‐KH560‐DE/EP composites. Curing kinetics showed that amine groups reduce apparent activation energy.

The current study investigates the wear behavior of three distinct composite compositions designated as C1, C2, and C3, with direct implications for aerospace applications. Critical factors such as the Coefficient of Friction (Cf), Specific Rate of Wear (Sw), and Frictional Force (FF) were meticulously analyzed using a systematic experimental approach and the Taguchi L27 array design. Significant relationships between input factors and responses emerged after subjecting these responses to Taguchi signal-to-noise ratio analysis. The optimal parameter combination of a 5% composition, 14.5 N Applied Load (Ap), 150 rpm Rotational Speed (Rs), and 40.5 m Distance of Sliding (Ds) highlights the interplay of factors in improving wear resistance. An Artificial Neural Network (ANN) was used as a predictive tool to boost research efficiency, achieving an impressive 99.663% accuracy in response predictions. The result shows comparison of the ANN's efficacy with actual experimental results. These findings hold great promise for aerospace applications where wear-resistant materials are critical for long-term performance under harsh operating conditions. The incorporation of ANN predictions allows for rapid material optimization while adhering to the stringent requirements of aerospace environments. This research contributes to the evolution of tailored composite materials, poised to improve aerospace applications with increased reliability, efficiency, and durability by advancing wear analysis methodologies and predictive technologies.
