“…Different types of additives have been successfully incorporated into the epoxy for different purposes. Although it is one of the mostly‐used thermosets in different applications, but it has some drawbacks, like brittleness due to its high cross‐link density [3] . The brittleness of the epoxy resins affects the damage tolerance, toughness, and impact strength, which restricts their applications [4] .…”

Fishbones are hydroxyapatite-based waste materials. They can be used in the form of particles as filler or additive in polymer composites. The surface of the particles can be modified using heat or thermal treatment. In this work, the fishbone particles (FBPs) were used in epoxy composites for the semi-structural applications. The composites were prepared using a solution-cast method. The effect of thermal treatment of the FBPs on the performance of the composites was investigated. The mechanical testing, thermo-gravimetric analysis, and differential scanning calorimetry measured the performance of the composites. The chemical structure and morphological properties of the composites were observed through Fourier transform infrared spectroscopy and scanning electron microscopy, respectively. Results showed that the tensile and flexural strength of the composites were improved by 30% and 200%, respectively, compared to the neat epoxy (NE) as an effect of the thermal treatment. It was also noticed that theT g , T m and T c of the modified composite were found significantly higher compared to other composites. The FBPs formed a hybrid domain within the composites when they interact with the epoxy. Such strong bonding can protect the composites from the external forces. Based on the performance, it can be suggested that the composites can be used where a semi-flexible scaffold is required.

“…When the temperature rises from 25 to 60°C, the thermal motion of molecules is intensified, resulting in degradation of polymer molecular chain and gradual breakage of the original macromolecular chain, and thus, obvious defects appears, [ 28 ] as shown in Figure 12B. The higher the temperature, the more obvious the degradation of polymer molecular chain.…”

In the actual working environment for the polymer cement composite, the effect of temperature on its properties cannot be ignored. In order to investigate the properties of polymer cement composite in extreme temperature environment, this study conducted bond test, tensile test, and shear test of composites at different temperatures (À30, À15, 25, 40, and 60 C). Through measuring the elastic recovery rate of specimens, as well as relevant strength indexes, deformation indexes and energy consumption indexes under tensile and shear loads, the effect of temperature on the bond property, tensile property, and shear property of the composite were investigated. The results show that the polymer cement composite has a good bond property, and no damage occurs at any temperature or after cold drawing and hot pressing cycle. Temperature has a great influence on the tensile property and shear property of polymer cement composite. At a low temperature, the tensile property and shear property improve, the strength and energy consumption indexes increase noticeably, and the elongation at break increases while the peak strain reduces in terms of deformation indexes. At a high temperature, the tensile property and shear property deteriorate, and the strength, deformation, and energy consumption indexes all fall. As a result, the polymer cement composite is more suitable for cold areas.

“…[1][2][3] Today, EP materials are widely used in automotive, aviation, rail transportation, and construction. [4][5][6][7] However, neat EP suffers a lot from its brittleness, fatigue resistance, and poor tribology behavior. [8][9][10] Therefore, various enhancers, such as carbon fiber, glass fiber, and natural fiber have been employed to overcome these shortcomings.…”

The chemical inertness of the basalt felt (BF) results in a weak interface bonding between BF and polymer matrix, which hinders the further application of BF reinforced composites. In this study, nickel‐based metal–organic framework (Ni‐MOF) sheets were decorated on the surface of BF by a facile one‐step hydrothermal method to improve the interfacial bonding between BF and epoxy resin (EP) matrix and embed solid paraffin. The mechanical and tribological properties of EP composites reinforced with BF were evaluated. The interfacial shear strength (IFSS) between BF and EP was measured by a single‐fiber drawing test, and the results indicated that the IFSS increased by 15.19% after MOF modification. The surface of BF transformed from hydrophilicity to hydrophobicity, therefore significantly improving the compatibility between EP and BF. Compared with pure EP, the composites exhibited improvements of 37.55% and 203.39% in tensile strength and tensile modulus, respectively. Meanwhile, the friction coefficient and specific wear rate of the composite decreased by 58.82% and 56.50%, respectively. The solid paraffin was observed to be enclosed by Ni‐MOF sheets, which endowed the composite with a self‐lubricating behavior during friction. This study will advance the comprehensive performance of EP and provide a versatile strategy for tuning the interface compatibility between the reinforcement material and the matrix. Highlights A novel Ni‐MOF decorated BF was developed for storage of PW. The BF/MOF/PW can simultaneously boost the tribological and mechanical properties of EP. Surface tailoring of BF was realized with decorating MOF sheets and embedding PW. A decline in friction coefficient by 58.82% was achieved.
