“…From Table 1, it is seen that the density of the composites increased with increasing SG and CF weight fractions. This is due to the fact that the density values of carbon fiber (1.8 g/cm 3 ) 23 and synthetic graphite (2.26 g/cm 3 ) are higher than the PPS and PPS−SPS blend.…”

Syndiotactic polystyrene (SPS) has attracted considerable attention recently due to its high melting temperature, low cost, and relatively low density value. The aim of the study is to reveal whether a blend of PPS and SPS (PPS–SPS) can be used instead of PPS for high thermal stability, high mechanical performance, and high thermal conductive material applications. For this aim, poly(phenylene sulfide)/syndiotactic polystyrene-based carbon-loaded composite materials were prepared using a twin screw extruder. Two carbon-based materials, carbon fiber (CF) and synthetic graphite (SG), were used to improve the mechanical properties and thermal conductivity of the PPS–SPS blends. Through-plane conductivity values of PPS-30SG-10CF and PPS–SPS-30SG-10CF were obtained to be 13.67 and 12.92 W/mK, with densities of 1.55 and 1.50 g/cm3, respectively. It was demonstrated that PPS–SPS blend-based carbon-loaded composites have great potential to be used in thermal management applications with the advantages of relatively low cost and lightweight compared to PPS-based composites.

Carbon fiber-reinforced polymer-matrix composites have been an important research topic due to their high performance and versatility. In this study, we investigated the mechanical, thermal, and electrical properties of short carbon fiberreinforced polypropylene (SCF/PP) composites prepared using the fused deposition modeling (FDM)-3D printing technique. PP was selected as the matrix for 3D printed composites to overcome the processing problems caused by the high content of SCFs. The addition of SCFs also effectively mitigated the warping problem during the PP cooling process. Compared to pure PP, the tensile strength increased by up to 35%, and the bending strength exhibited an approximate 40% enhancement. With increasing SCF content, the thermal conductivity exhibited a linear growth, reaching 0.266 W/(m • K) at 70 °C for the PPCF50 sample, simultaneously demonstrating excellent electrical conductivity. The material also displayed significant potential in electromagnetic protection applications, achieving a maximum shielding effectiveness of 29.8 dB. The texture direction and filling density in 3D printing settings have also been proven to play important roles in adjusting the performance of composite samples. The attempt of this study is beneficial for promoting the widespread application of polyolefin polymers as a consumable matrix material for 3D printed SCF-reinforced composite products.

“…The study for obtaining composites with excellent properties, which composed of various high-strength fibers as fillers, is not uncommon. 1,2 In particular, glass fiber has been widely used as a kind of strong and tough filler in the field of polymer composites, due to the low production cost and specific gravity, high strength, great chemical resistance and superior insulation properties. 3,4 Moreover, the properties of composites reinforced with fibers are affected by the mechanical properties of polymer matrix, the bearing capacity of fiber, and the interfacial compatibility between the polymer matrix and the fiber.…”

Fabrication of composites with hierarchically anisotropic structure and excellent mechanical properties is still challenging. Inspired by biological tissues with excellent anisotropic microstructure, in this study, a simple method for preparing robust anisotropic polyvinyl alcohol/glass fiber (PVA/GFs) composites with superior mechanical properties was proposed, which based on hydrogen bonding interactions and freeze–thaw method under tensile conditions. Surface‐initiated atom transfer radical polymerization (SI‐ATRP) was applied for grafting polymers onto the glass fiber. The glass fibers grafted with polymers (GFs) were introduced into PVA. After that, the freeze–thaw method under tensile conditions was adopted to control the formation of hierarchically anisotropic structure, which composed of anisotropic polymer network and orderly aligned glass fibers. The results also showed that the strength and toughness of the composites were significantly improved, due to the interfacial hydrogen bonding interactions between PVA and GFs. Therefore, this study could provide a meaningful idea for preparing anisotropic biomaterials with prominent properties for artificial tissues.
