Low-velocity and ballistic impact resistances of particle reinforced metal–matrix composites: An experimental study

Abstract

This study investigates the low-velocity and ballistic impact responses of SiC reinforced Al 6061 metal-matrix composites in different reinforcement volume fractions. Low-velocity impact (LVI) tests were performed with samples having SiC particle volume fractions of 0, 5, 10, 15, 20, 30, and 40%, while ballistic tests were carried out with samples having volume fractions of 0, 10, 20, and 30%. The weight-drop test method was used for LVI by applying 50 J (4.45 m/s) energy to all samples. Ballistic tests were carried out under the same conditions on all samples with the projectile launched at an average velocity of 500 m/s. For the determination of the ballistic resistance of the samples, the projectile penetrations in the witness structures were taken into consideration. The damage and deformations caused by both the LVI and the ballistic test in composites were examined. By the LVI test results, composite samples have absorbed less impact energy by increasing the reinforcement volume fraction, as well as demonstrated superior performance compared to unreinforced samples. In addition, the crack formation was mainly observed in the samples containing 30% reinforcement, while composite material with a 40% volume fraction was completely broken. With the increase in the reinforcement volume fraction, the ballistic resistance of the samples increased significantly.

Experimental and numerical study on projectile impact damage of EBC-SiC/SiC

“…The impact setup is a gas gun system (Hu et al, 2020(Hu et al, , 2021 which can control the impact velocity by through the gas pressure. Ekici and Kosedag (Ekici et al, 2022;Kosedag et al, 2022) and Srehari (Muniraj and Sreehari, 2022) conducted ballistic tests using projectiles of different materials at different speeds, as a reference for this experiment. In order to study the high-speed and low-energy impact of micro particle inhalers and make the results universal, a steel ball of 2 mm diameter was chose in this experiment.…”

Investigation of viscoelastic properties in composite sandwich panels subjected to low-velocity impact: Experimental and numerical approaches

“…1,2 Another important application of foam core sandwich panels is energy absorption at different stress levels and novel practical measures have been taken to enhance this property in the literature. 3–6 Analyzing the impact energy absorption of sandwich structures requires accurate modeling. However, due to the nature of the accurate simulations performed for this type of structure, which is often accomplished using numerical methods, simplifying approaches to reduce computational costs are inevitable.…”

Effect of SiC and graphene nanoparticles on the mechanical properties of carbon fiber‐reinforced epoxy composites

“…It is used as one of the abrasive materials due to its high hardness feature. 12,13 Selection criteria are majorly satisfied by low density (3.10-3.20 g/cm 3 ), high hardness (HV10 ≥ 22 GPa), high thermal conductivity (126 W/mK), high melting temperature (2730 C). From the stability perspective, neither salty acidic or basic solutions nor organic solutions pose a risk to silicon carbide chemically.…”
