Aerospace articles made from quasi-isotropic chopped prepreg
View Patent ↗Quasi-isotropic chopped prepreg is used to make parts found in aerospace vehicles. Exemplary aerospace parts that are made using quasi-isotropic chopped prepreg include aircraft window frames, wing fairing supports, flange supports, frame gussets, rudder actuator brackets, shear ties, seat pedestals, cargo floor flange supports, storage bin fittings, antenna supports, torque tube pans, handle boxes, side guide fittings, wing box covers and intercostals.
1. An assembly comprising:
a first aircraft part;
a second aircraft part; and
a third aircraft part for joining said first and second aircraft parts together wherein said third aircraft part comprises a cured quasi-isotropic chopped prepreg and wherein said third aircraft part comprises a first portion for attachment to said first aircraft part and a second portion for attachment to said second aircraft part wherein at least one of said first or second portions comprises a surface defining a hole through said first or second portion.
2. An assembly according to claim 1 wherein said cured quasi-isotropic chopped prepreg comprises a resin selected from the group consisting of epoxy, phenolic, bismaleimide and cyanates.
3. An assembly according to claim 1 wherein said cured quasi-isotropic chopped prepreg comprises fibers selected from the group consisting of carbon, glass, aramid and polyethylene.
4. An assembly according to claim 1 wherein said cured quasi-isotropic chopped prepreg comprises epoxy resin and carbon fibers.
5. An assembly according to claim 1 wherein said third aircraft part comprises a first portion for attachment to said first aircraft part and a second portion for attachment to said second aircraft part wherein said first and second portions are not in planar alignment.
6. An assembly according to claim 1 wherein said third aircraft part is selected from the group consisting of wing fairing supports, flange supports, frame gussets, rudder actuator brackets, shear ties, seat pedestals, cargo floor flange supports, storage bin fittings, antenna supports and intercostals.
7. An assembly comprising
a first aircraft part;
a second aircraft part; and
a third aircraft part for joining said first and second aircraft parts together wherein said third aircraft part comprises a cured quasi-isotropic chopped prepreg and wherein said third aircraft part is a cargo flange support and wherein said first aircraft part is a cargo floor and said second aircraft part is an aircraft fuselage.
8. An assembly according to claim 7 wherein said cargo flange support is capable of carrying a load of over 6000 pounds.
