Title:
改善された靭性を有する構造用複合材料
Document Type and Number:
Japanese Patent JP5715055
Kind Code:
B2
Abstract:
A structural composite comprising (i) a carbon fiber reinforcing material and (ii) a thermosettable resin composition; wherein the thermosettable resin composition comprises: a) thermosettable resin, and b) at least one amphiphilic block copolymer toughening agent comprising a polyether triblock copolymer; wherein the block copolymer toughening agent is a second-phase toughening agent, which self assembles into a second phase domain in the host thermosettable resin to improve its toughness; wherein the average Mode I strain energy release rate of the structural composite is from 200 J/m 2 to 1500 J/m 2 as measured according to ASTM D-5528-01, and wherein the glass transitional temperature (T g ) of the structural composite is from 70°C to 300°C as measured by Dynamic Mechanical Analysis.
