Abstract:
The current work investigates the influences of different surface modifications on the flexural characteristics of carbon fiber reinforced aluminum (AA2024-T3) laminates fabricated at 3/2 sequence. Among all types of surface modifications, mechanical abrasion by 220-grit paper shows highest flexural strength. The flexural load of Al/0/Al/0/Al configuration is about 19% higher in comparison with mechanical abrasion (220-grit paper) with chemical treatment due to higher interfacial strength. However, corrosion resistance is improved about 30 times in the later modification. Insitu imaging reveals that failure of Al/0/Al/0/Al laminates initiates by micro-buckling of carbon fiber whereas matrix cracking initiates the failure in Al/90/Al/90/Al laminates

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
