Carbon fiber reinforced polymer (CFRP) composites, which have good mechanical properties, are widely used in many sectors today. Carbon fabrics/epoxy composites are materials used in the production of various components in many professional in-dustries such as aerospace, construction, textile and automotive. The use of CFRP composite lightweight materials has begun to increase in the automotive industry to reduce emissions, increase crash resistance and save fuel. In order to evaluate mate-rials in these industrial areas, it becomes important to know their mechanical proper-ties such as tensile strength and three-point bending. In this study, carbon fiber rein-forced polymer (CFRP) [0°/0°], [0°/90°], [±45°] and [0°/90°/+45°/-45°/-45°/+45°/90°/0°] four different types of orientation CFR materials were used.Tensile and three-point bending tests were performed on the samples produced with 4 differ-ent orientation angles. Three-point bending tests were carried out in accordance with ASTM D7264 standards and tensile tests were carried out in accordance with ASTM D 3039 standards. Stress-strain and force-strain curves were drawn. It has been ob-served that the material type that withstands the maximum force the most is the C48 structured CFRP material with an 8-layer [0°/90°/+45°/-45°]s arrangement. However, it was concluded that the carrying capacity of the C48 sample was higher than the samples with different fabric orientation.

In this study, the impact of incorporating graphene oxide (GO) nanoparticles into the matrix of aramid fiber reinforced polymer (AFRP) composites was investigated. The GO nanoparticles were dispersed in the AFRP matrix at three different weight percentages: 0.1%, 0.3%, and 0.5%. The fabrication of the GO dispersed AFRP nanocomposites was achieved using the vacuum assisted resin infusion molding (VARIM) method, and the AFRP plates were cut using a water jet. The sectioned specimens of the fabricated nanocomposites were subjected to low velocity impact tests. The effects of introducing GO nanoparticles at different percentages were evaluated by analyzing the contact force, deflection, maximum absorbed energy versus time and contact force versus deflection curves. Finally, the key parameters of low velocity impact, including contact force, deflection, and maximum absorbed energy, were compared for the different fabricated AFRP nanocomposites. Based on the results, the AFRP composite with 0.3 wt.% of GO nanoparticles exhibited the best performance under low velocity impact loading conditions. However, the agglomeration of nanoparticles became a significant challenge when higher percentages of GO nanoparticles were added to the composite structure. The findings highlight the importance of determining the optimal percentage of nano materials for incorporation into composite structures.

The compatibility of the wrought Al-Ca alloy with the element Fe was investigated in the present study. In this work, both the Al-Ca alloy and Al-Ca-Fe alloy were synthesized through melting, casting, heat treatment, and rolling. A new ternary Al-Ca-Fe eutectic phase, identified as Al10CaFe2 with an orthorhombic structure, demonstrated enhanced performance, as revealed by nanoindentation tests. Combining the results of the nanoindentation and EBSD, it can be inferred that during the rolling and heat treatment process, the divorced eutectic phases were broken and spheroidized, and the structure of the Fe-rich alloy became finer, which promotes the formation of fine grains during the process of dynamic recrystallization and effectively hindered the grain growth during thermal treatment. Consequently, the strength of the as-rolled Al-Ca alloy was improved with the addition of 1 wt.% Fe while the ductility of the alloy was maintained. Therefore, adding Ca into the high-Fe content recycled aluminum altered the form of the Fe-containing phases in the alloy, effectively expanding the application scope of recycled aluminum alloy manufacturing. This approach also offered a method for strengthening the Al-Ca aluminum alloys. Compared to the traditional approach of reducing Fe content in alloys through metallurgical means, this study opened a new avenue for designing novel, renewable aluminum alloys highly compatible with impurity iron in scrap.
