DUAL CURE COMPOSITE RESINS CONTAINING URETDIONE AND USATURATED SITES |
| 摘要 |
The present invention provides a dual-cure composition containing multifunctional polyols, uretidiones, peroxide curable monomers containing unsaturation and crosslinking agents. The dual-cure composition may be used to form a high modulus material useful as the matrix in a prepreg material and in composites. The present invention also relates to methods for the production of the dual-cure composition, prepreg materials comprising the dual-cure composition and a fibrous support, and composites made from the prepreg material. |
