Abstract
Methods, systems and apparatuses are disclosed comprising a tunable multilayered array reinforcement system having a supramolecular adhesive embedded with nanoparticles that are reoriented on-demand in response to or in advance of vibrational effects in a moving or stationary structure.
Claims26
A method for changing the stiffness of a structure comprising the steps of:
- activating a multilayer system in the structure, said multilayer system comprising:
- a first layer comprising an adhesive embedded with nanoparticles, said adhesive have a first modulus value, and said nanoparticles oriented in a first orientation;
- a second layer proximate to the first layer, said second layer comprising a light activation system;
- and
- an energy input in communication with an energy source and said energy input in communication with the first adhesive layer;
- producing light in the second layer;
- directing light produced by the second layer to the first layer;
- altering the modulus of the adhesive from said first modulus value to a second modulus value;
- delivering energy from the energy source to the first adhesive layer via the energy input;
- and
- changing the orientation of the nanoparticles in the first layer.
