“…A flake composite consists of flakes that bond to the surface or are embedded in a matrix. The special properties that can be obtained are its oversized shape and flat surface [7]. Particulate composites are a type of composite where other materials in the form of powder/grain are added to the matrix.…”

The specimens were prepared with polyester polymer reinforced with natural fiber from three types of bamboo, namely Gigantochloa Apus, Bambusa vulgaris, and Bambusa blumeana. Their tensile properties were compared and investigated. In this paper, the specimen utilization of hand-wet layup processes of polyester resin with natural fibers. The fibers were treated with 5% NaOH solution to remove hemicellulose and create better debonding between matrix and fiber. Bamboo-reinforced composite of 3 types of bamboo with fractions 60% volume is thorn bamboo, Bambusa vulgaris, Gigantochloa Apus, and bamboo wipe without alkali. Of the three types of bamboo, the highest tensile strength of Gigantochloa Apus was soaked using NaOH with an average value of 37.06 MPa, with a tensile strain of 4.11%. In contrast, the lowest tensile strength value is Gigantochloa Apus which was not immersed in NaOH with an average of 13.79 MPa, a tensile strain of 2.54%. This matter shows the effect of immersion on tensile strength bamboo fiber composite. The results of the tensile strength of each type of bamboo obtained in this research, among others, bamboo thorn's tensile strength of 22.81 MPa, Bambusa vulgaris tensile strength of 16.69 MPa, bamboo apus 37.06 MPa, and Gigantochloa Apus without alkali 13.79 MPa. The observations show that Gigantochloa Apuscomposites are suitable for use as alternative tensile materials.

“…Aluminum matrix composites have drawn great attention from both scientific and industrial communities because of their superior specific thermal properties (thermal properties per unit density) and excellent machinability. The options for reinforcements in thermal management composites include SiC, diamond or carbon fibers [1][2][3][4][5]. Due to the favorable machinability for industrial applications, carbon fibers are the preferable reinforcements.…”

In this work, a molybdenum carbide coating on the surface of short carbon fibers prepared using molten salt method was proposed to ameliorate the interfacial bonding and improve the performance of carbon fiber/Al composites. The carbon fiber/Al composites were produced using vacuum hot pressing. The characteristics of molybdenum carbide coating were analyzed. Besides, the microstructures, bending strength and thermal properties of the carbon fiber/Al composites were explored. Furthermore, the interfacial thermal resistance of the composites was investigated in relation to theoretical evaluations derived from the combined Maxwell-Garnett effective medium approach and acoustic mismatch model schemes. The results indicated that a homogeneous Mo2C coating with a thickness of 0.5 μm was obtained by proper molar ratio of carbon fibers, MoO3 and chloride salts mixture and heated at 1000 °C for 60 min. The Mo2C coating greatly enhanced the bond between the aluminum matrix and carbon fiber, leading to improvements in the densification behavior and bending strength of the coated composites. The enhanced thermal properties including improved thermal conductivity and reduced coefficient of thermal expansion (CTE) were also achieved by the Mo2C coating. The in-plane thermal conductivity of 60 vol.% Mo2C-coated carbon fiber/Al composite was 221 W·m−1·K−1 enhanced by 92% compared to that of uncoated composite and the CTE was 6.0 × 10–6 K−1 which was suitable for electronic packaging materials.

“…Zhang 18 adding carbon fiber to graphene/copper matrix composites, hardness and tensile yield strength of composites were improved evidently by hybrid graphene/ carbon fiber addition. In previous studies, 19 our team improved the mechanical properties of graphite flakes/copper matrix composites by adding carbon fiber to the composites. Carbon fiber is uniformly distributed in the copper matrix without cross agglomerations when the content of carbon fiber is 2 wt %.…”

In this study, carbon fiber-graphite flake/copper composites were prepared by powder metallurgy. The impact of the alloying elements Ti and Zr on the composites’ properties was investigated, and the influence of varying Zr contents on the phase structure and thermal conductivity of the composites was also explored. The results indicate that composites containing Zr exhibit better flexural strength and thermal conductivity compared to those containing Ti. When the volume fraction of carbon fiber is 2% and 2 wt% Zr is added to copper matrix, the carbide layer at the composite interface is uniform and has a thickness of 0.36 μm. The thermal conductivity of the composite material is up to 597.5 W/(m∙K). The mechanical properties of the composites are enhanced by the synergistic effect of adding carbon fiber and alloying matrix and the composite shows a remarkable flexural strength of 150.5 MPa, which is 58.3% higher compared to composites without carbon fiber. Furthermore, the strengthening mechanism of carbon fiber on the mechanical properties of the composites was examined. The thermal conductivity of the multiphase composites was effectively predicted using the Acoustic Mismatch Model (AMM) combined with the MF module of Digimat software, and the impact of Ti or Zr elements on the composites’ thermal conductivity was analyzed.
