Fracture toughness of vinyl ester composites cured by microwave irradiation: preliminary results [PDF]

open access: yes, 2005
The shrinkage of vinyl ester particulate composites has been reduced by curing the resins under microwave conditions. The reduction in the shrinkage of the resins by microwaves will make the manufacture of large vinyl ester composite items possible.
