• T oday we dedicate this blog to the nanocomposite materials what could create stronger nanocomposites and calculation of high cycle fatigue. • Let’ s begin this way to make an analogy……if someone does a lot of arm curls at the gym it would typically result in a strengthening of the bones and muscles in their arms. The researchers at Ho ust o n’ s Rice University unexpectedly created a nanocomposite that behaves in the same way. Although the material which has no response to static stress repeated mechanical stress will cause it to become stiffer. • The splendid discovery was done in the lab of Pulickel Ajayan Rice University professor ofmechanical engineering and materials science and chemistry. Graduate student Brent Carey dis the task of creating a composite material by infiltrating a batch of vertically arranged multi-walled nanotubes with Polydimethylsiloxane which is an inert rubbery polymer. He was testing the high-cycle fatigue properties of the composite and was overwhelmed to discover that instead of weakening when subjected to repeated loads it actually got stronger.

• Over the duration of a week the material was subjected to about 3.5 million compressions. This caused its stiffness to enhance by 12 percent with further indications that there was potential to stiffen it more. The cause for this type of reaction is yet some sort of mystery. • Carey said that they were able to prevent further cross-linking in the polymer as an explanation. The data says that there is a very little chemical interaction between the nanotubes and the polymer and it seems that this fluid interface continuously evolves during applying stress. • What is known is that the use of nanomaterials greatly enhances the surface area available to that fluid interface so whatever reaction is occurring is much more pronounced than would be the case with a regular composite.

• Carey is already imagining potential uses for materials utilizing the process. He said that they can envision this response will be attractive for creating artificial cartilage that can respond to the forces being applied to it but remains elastic in areas which are not being stressed. • So hope you liked the information provided we shall keep updating in time. • If you want to take up CAD course in Pune then our CRB Tech Solutions has a name in this field for you to consider for enhancing your skill inmechanicalprograms and continue your career. • Our CAE training center provides the best mechanical projects through our mechanical engineeringinternships.
