Lattice Core Sandwich Construction

Abstract

A novel form of sandwich construction is disclosed. The lattice core sandwich construction comprises of elongate lattice cells in side-by-side abutment, to present common, lengthwise flat sides that have facesheets co-cured thereto without any secondary bonding. Each lattice cell is formed by wrapping, in alternate patterns, fiber-reinforced, composite bands around commonly-shaped mandrels. Oppositely disposed face sheets are placed against flat sides and the construction co-cured. After co-curing, the mandrels are removed.
