“…The outcome of this principle is that the protection to plastic deformation and work hardening capacity increase in the composites [39]. The indirect strengthening arises in the composites from the thermal mismatch due to uneven cooling between matrix alloy, which has a higher coefficient of thermal expansion (CTE) and ceramic particles with lower CTE [40]. The development of dislocations at the interface between matrix and reinforcement particle occur with a thermal mismatch, a result that is increased in dislocation density that contributes to improving the strength of the composites [37].…”

The stir-casting method was employed to study the effect of adding silicon carbide and the bamboo leaf ash into the Al-4.5wt.%Cu alloy. The standard procedure was followed in analysing the mechanical behaviour of the fabricated composites on parameters such as density, tensile strength, and hardness. Optical microscope, scanning electron microscope with energy dispersive analysis of X-rays, and X-ray diffraction analysis helped in studying the microstructure of the composites. The study reveals that the reinforcement particles in the matrix alloy were distributed nearly homogeneously, and with a clear interface. The X-ray diffraction patterns indicate the presence of silicon carbide and bamboo leaf ash without an intermetallic reaction. The density of the hybrid composites reduces with the addition of bamboo leaf ash, but porosity increases. The fabricated composites gain in tensile strength and hardness as the reinforcement particles are added, but elongation was decreased.

“…However, the gaps at the Al particle boundaries created by the existence of the MWCNTs were filled up with Al. It has been reported that and the thin Al 2 O 3 layer on Al particle can be fractured by the surface cleaning effect in SPS [17][18][19][20]. Therefore, it seems that Al has transformed to liquid phase in SPS, and infiltrated into the gap through the fractured Al 2 O 3 layer as can be seen by the white broken arrows in Figure 1b.…”

International audienceWe fabricated a uniformly dispersed and aligned multi-walled carbon nanotube reinforced aluminum matrix (Al–MWCNT) composite with minimal work hardening and without interfacial chemical compounds. In this paper, the direct load-bearing contribution of MWCNTs on the Al–MWCNT composite was investigated in detail for various volume fractions of MWCNTs. For up to 0.6 vol% of MWCNTs, the ultimate tensile strength (UTS) of the Al–MWCNT composite increased with the conservation of the remarkable failure elongation of Al. These UTS values are consistent with shear lag model. We also observed an uncommon multi-wall-type failure of MWCNTs during the hot extrusion process. However, owing to the agglomeration of MWCNTs in the Al matrix, the UTS deviated significantly from the shear lag model and the remarkable failure elongation of Al decreased. The possibility of strengthening, without degrading ductility, was demonstrated by exploiting directly the load-bearing ability of individually and uniformly dispersed aligned MWCNTs

“…Currently, in the automotive and aeronautical industries, thermomechanical properties have acquired great importance due to the different components used in these systems. In this sense, composites based on graphene, carbon fiber, fiberglass, and natural fibers have explored new applications in these two areas ranging from the manufacture of parts that constitute the external or internal structure of automobiles and aircraft and the electronic application that helps to protect and, at the same time, dissipate the heat [4][5][6][7][8][9][10][11].…”

“…In this work, the thermal properties of the composites formed by carbon fiber, glass fiber, and natural henequen fiber reinforced with a polymer matrix, aluminum, and alumina (Al 2 O 3 ) have been investigated. Under this context, studies showed that the addition of aluminum [25,50] and alumina particles in carbon fiber-based composites changes the thermomechanical properties [4]. On the contrary, the sheets used were carbon fiber (CF), glass fiber (GF), and natural henequen fiber (NHF), as shown in Table 1.…”

Currently, the automotive industry has made great advances in the incorporation of materials such as carbon fiber in high-performance cars. One of the main problems of these vehicles is warming, which is generated inside due to the heat transfer produced by solar radiation falling on the car, mainly on the roof. This research proposes the preparation of a composite material containing henequen natural fiber as a thermal barrier to be used as the roof of the car. In this research, 35 different laminates of 5 layers were prepared, combining carbon fiber, henequen natural fiber, fiberglass, and additives such as resin + Al2O3 or resin + Al. Reference samples were taken from stainless steel and one reference sample was extracted from the roof of the car. Considering the solar radiation and the heat transfer mechanisms, the temperature of the surface exposed to solar radiation was determined. The thermal conductivity of the 37 samples was determined, and the experimental results showed that the thermal conductivity of the steel with which the roof of the car is manufactured was 13.43 W·m−1·K−1 and that of the proposed laminate was 5.22 W·m−1·K−1, achieving a decrease in the thermal conductivity by 61.13%. Using the temperature and thermal conductivity data, the simulation (ANSYS) of the thermal system was performed. The results showed that the temperature inside the car with the carbon steel, which is currently used to manufacture high-performance cars, would be 62.34°C, whereas that inside the car with the proposed laminate would be 44.96°C, achieving a thermal barrier that allows a temperature difference of 17.38°C.
