Method for forming bends in composite panels and composite panels made thereby

摘要

A composite panel with a bend therein is formed by first and second adjacent panel sections having a common facesheet forming an outer radius of the bend, and a substantially void-free joint between the adjacent panel sections.

主权项

1. A composite panel having a curved bend therein, consisting essentially of:
a first panel section comprising a first core section having a first inclined surface and a first flange formed therein, the first core section sandwiched between a common facesheet and a first separate facesheet; a second panel section comprising a second core section having a second inclined surface and a second flange formed therein, the second core section completely divided from the first core section by a slot, the slot forming the first inclined surface and the second inclined surface, the second core section sandwiched between the common facesheet and a second separate facesheet, the common facesheet forming an outer arcuate surface of the curved bend; and a substantially void-free joint between the first panel section and the second panel section, in which the joint includes the first inclined surface and the second inclined surface engaged in substantially face-to-face contact along a plane passing through the radius of the curved bend.
