Abstract

The effectiveness of composite materials with the addition of activated carbon produced from biomaterial with a new application on aluminum-based composite materials was investigated in this study. Activated carbon was produced from the peanut shells via the chemical activation method and the obtained activated carbon was mixed with aluminum and composite material. For the characterization of the composite material obtained, XRD and SEM–EDS optical photographs were assessed in the experimental process. According to Vickers Hardness and Dynamic Micro Hardness results, the sample with the hardness value of 2% AC added had the highest hardness value. The value of the elastic modulus was found to be 9.59GPa with an increase of 3.4 times compared to aluminum with 2% activated carbon addition. This increases with activated carbon quantity, and weakens the composite structure due to weak van der waals interaction with aluminum, which reduces hardness; therefore, the best ratio of the activated carbon reinforcement to the aluminum matrix was obtained at 2% activated carbon addition.

Highlights

Aluminum and aluminum composites are used very frequently in areas such as automotive, aerospace industry due to their properties such as high thermal and electrical conductivity and good corrosion resistance[1]

According to the SEM images of the samples used in the production of active carbon, additional composite materials were obtained from vegetables when aluminum is used as matrix; so, it is obvious in the SEM and mapping images that 2, 4 and 6% of the masses added to the Al matrix were homogenously distributed in the matrix

Summary

Introduction

Aluminum and aluminum composites are used very frequently in areas such as automotive, aerospace industry due to their properties such as high thermal and electrical conductivity and good corrosion resistance[1]. Metals having a reduced specific gravity have useful mechanical characteristics including strength, which provides the required strength with less weight, and thereby reducing fuel and operating costs. They have high electric and thermal conductivity, high damping capacity, and high corrosion resistance [4]. One of the main reasons to conduct the current research was to find out which material is appropriate for composite preparation. Since it is a metal matrix composite, we had several options to fill up the slots of the matrix and several options for reinforcement materials. Mechanical characteristics and the wear resistance of Al 7075 graphite composites were studied during research [7], into carbon-reinforced aluminum composites [8] and characteristics and microstructures of
