Impact localisation with FBG for a self-healing carbon fibre composite structure

We demonstrated the localisation of impacts in orthotropic carbon fibre reinforced polymer (CFRP) composite materials to within a few centimetres, using a sparse array of fibre Bragg grating (FBG) sensors. This type of sensor is easily embedded in composit ...

Active sensing and repair composites

Eva Kirkby

This thesis describes the development of a smart carbon fibre polymer composite that is capable of sensing its own damage and self-healing. Structural composites are used in the aerospace and marine industries, for example. During their lifetime impact eve ...

Tailored processing of epoxy with embedded shape memory alloy (SMA) wires

Véronique Michaud, Eva Kirkby, Julie O'Keane

We present the development of a low-temperature liquid composite moulding cure schedule that is compatible with the fabrication of shape memory alloy (SMA)–epoxy composite materials. With this process, the SMA wires do not need to be maintained in place wi ...

Performance of self-healing epoxy with microencapsulated healing agent and shape memory alloy wires

Véronique Michaud, Eva Kirkby

We report the first measurements of a self-healing polymer that combines a microencapsulated liquid healing agent and shape memory alloy (SMA) wires. When a propagating crack ruptures the embedded microcapsules, the liquid healing agent is automatically re ...

Low temperature moulding of adaptive composites with embedded shape memory alloy wires

Véronique Michaud, Eva Kirkby, Julie O'Keane

The feasibility of using a low temperature liquid composite molding technique to produce smart composites with embedded shape memory alloys was investigated. The epoxy system of EPON 828 resin and DETA hardener was evaluated, with embedded NiTiCu shape mem ...

Embedded Shape-Memory Alloy Wires for Improved Performance of Self-Healing Polymers

Véronique Michaud, Eva Kirkby

We report the first measurements of self-healing polymers with embedded shape memory alloy (SMA) wires. The addition of SMA wires shows improvements of healed peak fracture loads by up to a factor of 1.6, approaching the performance of the virgin material. ...
