In this study, a reduction of 7.8–10.37% in the blade mass was achieved by optimizing the thickness of unidirectional spars in the Sandia 100-m all-glass baseline blade for a 13.2 MW wind turbine. The optimized design still complies with stiffness, s... Read More about Effective utilization of unidirectional laminates for mass reduction in composite blades of multi-MW wind turbines..

Portland cement is the predominant material for permanent abandonment of oil and gas wells. However, resins are increasingly finding applications in the mix of barrier materials for plug and abandonment of wells because of unique features that enable...

The addition of stiff nanoparticles to a polymer matrix usually proves beneficial for the enhancement in stiffness and strength, however, the impact strength is usually lowered. Conversely, the use of elastomeric additives can enhance the toughness a...
