SYSTEM FOR INSERTING ELEMENTS IN COMPOSITE STRUCTURE

摘要

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.
