METHOD AND SYSTEM FOR INSERTING REINFORCING ELEMENTS IN A COMPOSITE STRUCTURE

摘要

A method of and system for inserting reinforcing pins in a composite structu re in which a number of reinforcing pins (22, 24, 26) are inserted in a compressible material (28); 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 by an ultrasonic transducer (34) to compress the compressible material and insert the pins into the composite structure to jo in two laminates (30, 32) or reinforce a single composite structure.
