Process-induced deformation in U-shaped honeycomb aerospace composite structures

This study presents the findings of a combined experimental and numerical investigation to study process-induced deformation in sandwich structures manufactured using autoclave molding techniques. U-shaped sandwich structure based on woven carbon prepregs and an over-expanded Nomex honeycomb core were manufactured. For purposes of comparison, a U-shaped composite laminate, i.e. without the inclusion of a core, was also manufactured and modeled....
