THREE-DIMENSIONAL KNIT SPACER FABRIC SANDWICH COMPOSITE.

摘要

The present invention relates generally to the use of a three-dimensional knit spacer fabric component material in the fabrication of a sandwich core interface composite. More specifically it relates to the use of such a spacer fabric as a skin-to-core laminate interface to enhance laminate bonding, and particularly to enhance the interface planarity of monolithic cores grid cut to approximate curvatures in a mold tool and avoid discontinuities in the composite structure.
