High performance, damage tolerant fibre reinforced polymer (FRP) composite materials are currently required to demonstrate no propagation of any sub-surface structural micro-cracking when under service load, thereby encouraging overdesign and limiting the inherent lightweight nature of such a material. By incorporating selfhealing...

Self-healing polymers typically feature monomer and catalyst either dispersed within a host matrix, or encapsulated within hollow vessels. Unprotected highly active catalysts, sensitive to air and moisture, can readily react with amine cross-linking agents during the cure of reactive prepolymers e.g. epoxy resins. Therefore, catalysts stable to...

Fibre reinforced polymer composite materials are becoming more widely adopted for high performance industrial applications. The hierarchical nature of these materials offers a unique opportunity to incorporate multi-functionality whilst maintaining their excellent mechanical properties. Ideally, multifunctional composites can be configured to...

Locally stiffened or ‘stringer’ - skin composite structures are extensively used for lightweight applications in the aerospace industry. Due to localised stiffening, stress concentrations arise which can initiate damage e.g. debonding or delamination, within the composite structure. Critically, this damage can propagate under fatigue loading...

A new approach to self-healing systems is presented that aims to overcome the inherent drawbacks of conventional liquid resin based healing systems within composites. Finite embedded systems offer limited healing potential for small volume delaminations and as such cannot effectively heal large damage volumes often associated with shear damaged...
