Effect of Transverse Low Velocity Impact Damage on Torsional and Bending Strength and Effect of Chemical Reactivity of Hybrid Aluminium/Composite Tubes - A Review

The major reasons for switching toward composite materials are due to their properties of higher specific stiffness, strength and performance that are comparable with conventional materials. Nowadays, the use of composite materials in our lives has become very common and these are found application as drive shaft, building and infrastructural system, landing gears for helicopters, furniture, transportation, rocket structures, tube structures for sports equipment, , truss structures, robot arms. Low velocity Impact damage during the service life of structures made up of composite materials is a major importance since its mechanical strength can be tremendously reduced as a result of such damage. Recently the interest of researchers has been directed towards on low velocity impact damage and the prediction of residual strengths of damaged fiber-reinforced composite materials, using them as potential substitutes for metals. These statistics indicate that this is a very dynamic area of research, and the main focus of present article seeks to provide comprehensive review of previous and recent research work published on torsional and bending strength of hybrid composite structures after low velocity impact damage. Fabric of carbon/glass wound around the aluminum tube by the use Araldite Epoxy and Hardener. This paper attempt to review the fabrication technique and mechanical properties chemical reactivity (by use NaCl) of twill woven fabric of Carbon/Glass based aluminum composite tube.
