METHOD OF MAKING A FILLED HONEYCOMB CORE COMPOSITE STRUCTURE

摘要

The invention is a method of making a foam filled honeycomb core structure (11) comprising the steps of: 1) providing a honeycomb core billet (10); 2) reinforcing the honeycomb core with foam (14); 3) placing the foam filled billet (10B) in a mold (28) having a curved mold surface (30); 4) creep forming the foam filled billet (10B) to the general shape of the structure (11) by applying a load (41) to the foam filled billet (10B); and 5) machini ng the creep formed billet to the actual shape of the structure (11).
