Title:
USE OF FIBROUS VEILS TO REDUCE CORE CRUSH IN HONEYCOMB SANDWICH STRUCTURES
Document Type and Number:
WIPO Patent Application WO/2018/187275
Kind Code:
A3
Abstract:
Light weight fibrous veils are incorporated into the uncured composite iace sheets of a tioiieycomb sandwich structure in order to reduce the la teral crushing of the honeycomb (core crush) that occurs during curing of the uncured structure in an autoclave or vacuum bag system. The light weight fibrous veils act as friction-promoting layers to reduce the relative movement of the uncured face sheets that leads to core crush during the curing process.
