Ambrose is a Reader in Materials Engineering, and is the leader of the ‘Nanomaterials’ group which specialises in the characterisation and modelling of particle-modified thermoset polymers. He has researched the impact and durability performance of rubber-toughened structural epoxy adhesives, and quantitatively predicted the lifetime of adhesive joints in fatigue. His current work is investigating the structure/property relationship of thermoset/inorganic hybrids, using epoxy, acrylic and cyanate ester polymers. He also has interests in using other nanomodifiers (e.g. layered silicates, carbon nanotubes and silica nanoparticles) as tougheners for thermosets. He is also investigating the microstructure and properties of epoxy adhesives modified with combinations of micro- and nanoparticles. The applications of these materials include structural adhesives, coatings and as the matrices of fibre-composite materials. He has held a prestigious Royal Academy of Engineering Post-doctoral Research Fellowship and a Royal Society Mercer Award for Innovation.
Ambrose heads the Nanomaterials Research activity.
The Nanomaterials group is concerned with measuring, modelling and predicting the performance of polymers and composites modified with nanoparticles, and with the formation of nanostructure materials. There is special emphasis on the fracture performance of these materials.
