Reversible shape memory multifunctional structural designs and method of using and making the same

A multifunctional member adapted for reversible structural deformation from a first shape to a second shape, the multifunctional member comprising:

• a first active member, said first active member adapted to contract if exposed to a temperature above a first transition temperature range;
• a second active member, said second active member adapted to contract if exposed to a temperature above a second transition temperature range;
• at least one core member, wherein said first and second active members are connected to opposite sides of said core member;
• at least one heat source operatively connected to said first and second active members to expose said first and second active members to said first and second temperatures, respectively;
• wherein said first and second active members are operable to alter the shape of the multifunctional member between said first and second shapes, wherein:
• said first active member contracts while above said first transition temperature range causing said at least one core member to bend out-of-plane and thereby causing said second active member to expand, whereby said multifunctional member assumes said first shape;
• said second active member contracts while above said second transition temperature range causing said at least one core member to bend out-of-plane and thereby causing said first active member to expand, whereby said multifunctional member assumes said second shape;
• wherein said multifunctional member retains each of said first and second shapes after exposure to said first and second temperatures by said at least one heat source has been stopped;
• and
• wherein said core is comprised of at least two corrugated layers with a center sheet disposed between adjacent said corrugated layers.
