Abstract
A cascade for a jet engine thrust reverser is fabricated by co-consolidating pre-consolidated thermoplastic strongbacks and vanes. The strongbacks are reinforced with continuous fibers, and the vanes are reinforced with discontinuous fibers.
Claims21
A cascade for a jet engine thrust reverser, comprising:
- a plurality of strongbacks each formed of a polymer resin having a continuous fiber reinforcement;
- and
- a plurality of vanes joined to the strongbacks and each formed of a polymer resin having a discontinuous fiber reinforcement.
A cascade for a jet engine thrust reverser, comprising:
- a pre-consolidated thermoplastic strongback assembly;
- and
- pre-consolidated thermoplastic vanes co-consolidated with the strongbacks.
10-17. (canceled)
Apparatus for co-consolidating a plurality of strongbacks and a plurality of vanes, comprising:
- a tool including a plurality of hard tool inserts fixed in relationship to each other and capable of being inserted into a first set of cavities formed by the vanes;
- and
- a plurality of mandrels capable of being individually inserted into a second set of cavities formed by the vanes.
