Abstract

This paper describes the design and manufacture of a laminate which, when heated, will deploy into an expanded mesh. The design exploits the bending and/or twisting curvature that results when a non-symmetric laminate is subjected to a temperature change. To ensure the mesh laminate is almost flat after curing (i.e. prior to deployment), layups consisting of non-symmetric sublaminates separated by thermoplastic interleaves have been developed. When such a laminate is subsequently heated above the Tg of the thermoplastic layers, the mesh deploys. Two different layups are investigated; one deploys into a planar mesh and the other deploys into a mesh which forms a curved surface.
