Abstract
The present disclosure provides a curable resin composition including a thermoset resin, an aliphatic polyketone as a toughener and a hardener. The curable resin composition may be combined with reinforcing fibers and then cured to form a fiber-reinforced composite article having a high glass transition temperature, excellent mechanical properties and low moisture absorption. The fiber-reinforced composite article may be used in various applications, such as in transport applications including aerospace, aeronautical, nautical and land vehicles.
Claims15
A curable resin composition comprising (a) from wt. % to wt. %, based on the total weight of the curable resin composition, of a thermoset resin, (b) from 2 wt. % to 12.5 wt. %, based on the total weight of the curable resin composition, of an aliphatic polyketone toughener, and (c) from 15 wt. % to 25 wt. %, based on the total weight of the curable resin composition, of a hardener, and from 15 wt. % to 25 wt. %, based on the total weight of the curable resin composition, of an additional toughener, wherein the curable resin has a glass transition of at least 190° C. after curing.
