Damage-tolerant, laminated structural supercapacitor composites enabled by integration of carbon nanotube fibres

Review of Damage Tolerant Analysis of Laminated Composites

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...

Hierarchical Composites with Carbon Nanotube Grafted Fibres

Carbon nanotubes (CNTs) are excellent candidates for a new generation of high-strength, high-stiffness materials due to their low density, high aspect ratio and intrinsically superior mechanical properties. The present study investigates the feasibility of reinforcing conventional fibre/matrix composites by grafting CNTs onto the fibre surface. The approach is to exploit the CNT performance to ...

Highly deformation-tolerant carbon nanotube sponges as supercapacitor electrodes.

Developing flexible and deformable supercapacitor electrodes based on porous materials is of high interest in energy related fields. Here, we show that carbon nanotube sponges, consisting of highly porous conductive networks, can serve as compressible and deformation-tolerant supercapacitor electrodes in aqueous or organic electrolytes. In aqueous electrolytes, the sponges maintain a similar sp...

‌Progressive Damage Analysis of Laminated Composites using Continuum Damage Mechanics

In this paper, progressive damage and global failure of composite laminates under quasi-static, monotonic loading are investigated using 3D continuum damage mechanics. For this purpose, a finite element program has been developed using an eight-node 2D layered element including layer-wise plate theory. Damage analysis of a single orthotropic layer under various uniform in-plane and transverse l...
