“…Fibers are widely used as reinforcements in friction materials, building materials, refractory materials, and high-temperature filter fabrics [ 20 , 21 , 22 , 23 ]. In composite materials, fiber materials serve as reinforcements to withstand loads during matrix cracking, maintaining the matrix integrity and improving its damage resistance [ 24 , 25 , 26 ]. It has been found that carbon fibers (CFs) can improve the tensile strength and impact resistance of composites [ 26 , 27 , 28 , 29 , 30 ].…”

Various contents of carbon fibers (CFs) and potassium titanate whiskers (PTWs) were added to an Fe-based impregnated diamond bit (IDB) matrix to enhance its adaptability to percussive–rotary drilling. A series of mechanical tests were conducted successively to find the effects of the reinforcing materials on the properties of the Fe-based IDB samples. Then, the fracture surfaces of the samples were analyzed via scanning electron microscopy (SEM) and energy-dispersive spectroscopy, and the worn surfaces and abrasive debris of the samples were analyzed using a laser scanning confocal microscope and SEM. The results show that both the CF and PTW can effectively improve the hardness and bending strength of an Fe-based IDB matrix, and those parameters reached their maximum values at the additive amount of 1 wt%. However, the CF had a better enhancement effect than the PTW. Furthermore, the CF improved the impact wear resistance of the IDB matrix, with a minimum wear rate of 2.38 g/min at the additive amount of 2 wt%. However, the PTW continuously weakened the impact wear resistance of the IDB matrix with increases in its content. Moreover, the morphologies of the worn surfaces indicated that the minimum roughness of the CF-reinforced IDB matrix decreased significantly to as low as 4.91 μm, which was 46.16% lower than that without CF, whereas the minimum roughness of the PTW-reinforced samples decreased by 11.31%. Meanwhile, the abrasive debris of the CF-reinforced samples was more uniform and continuous compared to that of the PTW-reinforced samples. Overall, the appropriate addition of CF or PTWs can enhance the mechanical properties of Fe-based IDB matrices, which can be used on different formations based on their impact wear resistance.

“…However, pure PEEK is not preferred for structural components like body side panels, underbody structures, and interior ttings due to its relatively lower modulus than traditional structural metals. To mitigate this, PEEK-based composites are generally used for high-strength applications [9,10]. Furthermore, PEEK can easily be compounded with inorganic reinforcements like carbon, graphene, glass, titanium, and silica for higher stiffness and superior mechanical properties.…”

PEEK has several approving mechanical properties; however, for certain demanding applications such as automotive, PEEK does not exhibit the required strength. Moreover, if the PEEK parts are developed by Fused Filament Fabrication (FFF)-based 3D Printing, there is a high chance of having PEEK parts with decreased mechanical properties. Carbon Fiber (CF) reinforcement is a well-known method of mitigating the low mechanical properties of PEEK. Hence, in the present study, we attempted to develop CFreinforced PEEK (CFR-PEEK) parts via FFF. First, we developed homogeneous CFR-PEEK mixtures via ball milling and explored the effects of different milling duration and speeds on the extent of uniform dispersion of the CFs in the PEEK matrix. Next, we fed the CFR-PEEK milled powders into a hightemperature extrusion setup to develop uniform-diameter CFR-PEEK laments. We analyzed the effects of different extrusion parameters on the uniform-diameter CFR-PEEK lament quality to make it suitable for 3D Printing. Finally, the CFR-PEEK laments were used in a high-temperature FFF setup to develop designspeci c parts. Our results indicate that 400 rpm and 4h were apt for developing uniform CFR-PEEK mixtures. Interestingly, increasing the CF content above 10 vol% resulted in brittle laments. The extrusion temperature, speed, and cooling rate played a major role in forming the uniform-diameter CFR-PEEK laments. Finally, the 3D printed CFR-PEEK parts exhibited a tensile strength of 49MPa, lesser than un lled PEEK. We indicate that poor interfacial bonding of the CF with the PEEK matrix is a primary reason for this reduced strength. In addition, printing defects such as pores also contributed to the reduced strength of the CFR-PEEK parts.

Polyphenylene sulfide sulfone (PPSS) was synthesized by one‐step method and utilized as a sizing agent for carbon fibers. The effects of various monomer ratios, reaction time, and reaction temperature were investigated on the molecular weight of PPSS. The thermal analysis revealed that the product PPSS exhibited a glass transition temperature exceeding 215.5°C, indicating exceptional thermal stability. After PPSS sizing treatment, the grooves on the surface of carbon fibers were filled, resulting in a substantial enhancement of the microinterface properties. The surface energy was increased by 8.2%, while the maximum weight loss temperature was 27.8% higher than that of the commercial carbon fiber. The tensile strength of the carbon fiber after heat treatment reached 2196 MPa, representing a 45.9% increase over that of the commercial carbon fiber.
