A fan blade comprises interleaved plies, where interleaving comprises distributing wide plies within narrow plies and short plies within long plies in the fan blade; wherein the interleaving is defined as an actual intersection of a plurality of plies of different variable dimensions that extend in the chordwise direction with another plurality of plies of different variable dimensions that extend in the spanwise direction such that their respective longitudinal axes intersect with one another at angles of 5 to 175 degrees.

Composite fan blade airfoil, methods of manufacture thereof and articles comprising the same

A method for making a composite article comprises securing a layup over a form. The layup including a plurality of dry intermediate reinforcement plies wrapped around an inner reinforcement ply. Resin is infused into the layup under vacuum. The resin-infused layup is consolidated under pressure and cured.

In-situ pressure enhanced processing of composite articles

A fan containment case for a gas turbine engine includes a first inner layer and a second layer outside the first inner layer, where the second layer is made of a first material having a first fabric architecture. The fan containment case also includes a third layer outside of the second layer, where the third layer is made of a second material having a second fabric architecture, and at least one of the first material and the first fabric architecture of the second layer is different from the second material and the second architecture, respectively, of the third layer. A fourth outer layer is located outside of the third layer.
