Processing, Characterization And Evaluation Of A Functionally Graded Ai - 4.6% Cu Alloy
(Indian Institute of Science, 2005-12-22)In some applications the stress across the entire cross-section of a component is not uniform but varies with position. For example, maximum shear stress is highest at the inner surface of a thick-walled cylinder subjected ... -
Structure-Property correlation in epoxy composites containing carbonaceous nanoparticles
Epoxy is widely used as thermosetting materials in carbon fiber composites due to its combined superior thermal and mechanical properties which makes them a potential candidate for myriad applications. But epoxy suffers ... -
Tufting of carbon fibre/epoxy composites for improved damage tolerance
Laminated composite structures are susceptible to delamination and debonding during their service life due to their poor out-of-plane interlamellar properties. Such damage can occur either during manufacturing or during ...
