Abstract
The properties of selected electron-curable polymers and co-polymers are examined and their suitability as composite matrix materials and adhesives investigated. The effects of radiation dose on the molecular weight distribution, glass transition temperature and carbon fibre composite flexural modulus are reported. The variation in processing conditions through-the-thickness is determined for composites up to 3.5 cm in thickness using both electrons and X-rays. Single lap shear tests, carried out on electron-cured vinyl-ester and acrylated isocyanate bonded joints are described. Some of the practical considerations of carrying out bonded repairs using a portable electron accelerator or isotope source are also discussed.
