Abstract
Bumper is a front or rear part of automobiles. It is designed and shaped to be impact
absorbing and protecting automobiles from damage in low impact collisions. Initially,
they were made from heavy steels, increasing the weight of automobiles and fuel
consumption. Also, high impacts of steel bumpers on pedestrians during accidental
collision cause fatalities and or disabilities. An effort to enhance fuel efficiency, safety,
freedom of design and shape detailing, heavy alloys for automobile applications are now
being replaced with polymeric composites. Aluminium micro particles and nanoparticles
were prepared from aluminium cans through sand casting, lathe machine spinning, and
ball milling techniques. Both types of aluminium particles were incorporated into a
mixture of diglycidyl ether of bisphenol A (DGEBA, epoxy resin) cured with amine base
hardener (ABH). Phases of the epoxy polymer and composites were identified using Xray Diffraction (XRD). Spatial arrangement of the phases within the matrix and their
elemental composition were examined using Scanning Electron Microscope with
attached energy dispersive X-ray spectroscopy (SEM/EDX). Tensile, impact and micro
hardness tests were conducted on the prepared epoxy/aluminium composites. Results of
the XRD showed the presence of aluminium compounds/phases due to chemical reactions
between aluminium particles and DGEBA/ABH system. SEM confirmed a homogeneous
distribution of the phases within the epoxy matrix, and that there is a strong adhesion
between the epoxy matrix and aluminium particles. Correlation between the mechanical
properties of the prepared nanocomposite and the procured bumper materials exhibited a
fair suitability of the prepared nanocomposites for automobile applications.
