PROBLEM TO BE SOLVED: To provide a system and method for improving properties of a resin such as reducing the difference in the resin coefficient of thermal expansion (CTE) between the resin and fibers and reducing the cure shrinkage of the resin.SOLUTION: A composition includes a resin and a plurality of polymer nanoparticles contained in the resin to form a resin mixture. The resin has at least one of a CTE, a resin cure shrinkage, and/or a resin heat of reaction. The plurality of polymer nanoparticles have at least one of nanoparticle cure shrinkage less than the resin cure shrinkage, a nanoparticle CTE different than the resin CTE, and/or a nanoparticle heat of reaction less than the resin heat of reaction. At least some of the polymer nanoparticles comprise: polymer nanoparticles having a non-elastomeric thermoset component; and polymer nanoparticles formed of thermoplastic material without an elastomeric component.SELECTED DRAWING: None |
