Abstract

People propose higher and higher demands for lightweight materials due to the increasing shortage of metals and energy sources. Since traditional aluminum alloy materials cannot meet demands any more, aluminum-based composites attracted high research attentions in recent years because of the excellent mechanical properties and low density. Silicon carbide (SiC) reinforced aluminum-based composite and carbon nanomaterial reinforced aluminum-based composite are two aluminum-based composites which are used mostly in existing associated studies. The former one has a long research history and it has been applied to aerospace, war industry and automobile field to some extent. The later one is an emerging material that is hardly applied yet. This study is going to introduce research progresses and applications of SiC reinforced aluminum-based composite and carbon nanomaterial reinforced aluminum-based composite.

Highlights

  • Since the development of fused salt electrolysis process in 1866, Al enters into the stage of industrialized mass production

  • This study mainly introduces research progresses and applications of the current mainstream fibers or whisker reinforced Al-based composites as well as the particle reinforced Al-based composites

  • As by-product from industrial production, Silicon carbide (SiC) particles incur significantly lower manufacturing costs compared to silicon carbide fiber (SiCF), whisker, monofilament, etc

Summary

Introduction

Since the development of fused salt electrolysis process in 1866, Al enters into the stage of industrialized mass production. The development of modern society advocates green economy, energy conservation and emission reduction, which propose many new requirements on materials, including low density, high strength, high rigidity, high tenacity, and adaptation to very tough environments such as strong corrosion, high temperature or ultra-low temperature and high radiation. Al alloy material has an application history of more than 100 years, it still has limitations as a metal. Al-based composites are superior for the higher strength, higher rigidity, stronger friction resistance and low expansion rate in addition to some excellent properties of Al alloy. This study mainly introduces research progresses and applications of the current mainstream fibers or whisker reinforced Al-based composites as well as the particle reinforced Al-based composites
