Thermally Activated Composite with Two-Way and Multi-Shape Memory Effects [PDF]

Materials, 2013
The use of shape memory polymer composites is growing rapidly in smart structure applications. In this work, an active asymmetric composite called “controlled behavior composite material (CBCM)” is used as shape memory polymer composite. The programming and the corresponding initial fixity of the composite structure is obtained during a bending test ...
