Lockheed Martin's F-22 extensively uses thermoset composites, with bismaleimide and toughened epoxy comprising up to 17.5% and 6.6% of the structure by weight respectively.[13] Lockheed Martin's F-35B (a STOVL version of this US fighter) is reportedly composed of bismaleimide materials, in addition to the use of advanced carbon fiber thermoset polymer matrix composites.[14] |
