With advanced composites increasing replacing traditional metallic materials, the material inhomogeneity and inherent anisotropy of such materials lead to not only new attributes for aerospace structures, but also introduce new technology to damage tolerant design and analysis. The deleterious effects of changes in material properties and initiation and growth of structural damage must be addre...

Damage in composite materials occurs at multiple scales, from matrix cracking and fiber/matrix debonding to ply delamination, and is complicated due to the different failure mechanisms interacting with the composite microstructure. Recent progress in the development of advanced techniques for structural health monitoring (SHM) has been aimed at techniques capable of sensing damage in situ and i...

The insect cuticle is a typical natural composite with excellent strength, stiffness, and fracture toughness. Scanning electron microscope observation of the microstructure of Hydrophilidae (an insect) cuticle showed several unique plies and structural characteristics, which may provide available information to the design of advanced composites. The microstructure found in the vicinity of pore ...

The increasing use of composite materials in many advanced structures brings with it a need to establish inspection and monitoring regimes to ensure structural integrity and safe operation throughout the service life. This results in the fast-growing composite industry searching for a technologically and economically feasible structural health-monitoring method to identify and assess defects/cr...

Abstract Electrochemical water splitting is a promising pathway for effective hydrogen (H 2 ) evolution in energy conversion and storage, with electrocatalysis playing key role. Developing efficient, cost-effective stable catalysts or electrocatalysts critical from splitting. Herein, we evaluated graphene-modified nanoparticle catalyst reaction (HER). The electrocatalytic H production rate of r...
