Doubly Curved Composite Sandwich Panels for Hybrid Composite/Metal Ship Structures

摘要

Doubly curved composite sandwich panels loaded by evenly distributed pressure were designed, analyzed, manufactured and tested. Quick and cost effective methods for making molds for vacuum infused doubly curved composites were studied and implemented. Several different manufacturing techniques for making doubly curved panels and doubly curved foam cores were investigated. Tests were performed using a hydrostatic water tank.
