摘要:
A continuous intersecting braided composite preform including a first member with at least one ply of biased fibers and a second member also with at least one ply of biased fibers. The first member intersects with the second member and passes continuously through the second member such that the biased fibers of the first member are interstitially arranged with respect to the biased fibers of the second member at the intersection.

摘要:
A method of manufacturing a composite turbine rotor in which blade coupons are fabricated from flat braided fabrics that have extending axial fibers. The extending axial fibers are then woven between the plies of polar woven fabric which make up the body of the rotor. This preform assembly is then impregnated with resin and cured. The blade coupons make up the blades of the rotor and can be made to have an airfoil shape, a curved shape, or a twisted shape by the use of blade formation tools designed for forming the rotor preform.

A method of and system for inserting reinforcing pins in a composite structure in which a number of reinforcing pins are inserted in a compressible material; the compressible material/pin combination is assembled on the composite structure; ultrasonic energy is applied to the pins; and pressure is applied simultaneously with the application of ultrasonic energy to compress the compressible material and insert the pins into the composite structure to join two laminates or reinforce a single composite structure.
摘要:
A braiding machine carrier having a frame; a fiber spool mount attached to the frame; a fiber take-up assembly including a spiral spring; gear train on the frame for mechanically connecting the take-up spring assembly to the fiber spool mount for winding the spiral spring as a spool on the mount rotates; and a magnetic clutch, coupled to the take-up spring assembly, for preventing overwinding of the spiral spring.
