Abstract: A method of forming lightweight structures from particle networks includes functionalizing edges of particles of an anisotropic material, exfoliating of the particles to form sheets of the material, aligning the sheets of material to form a network of multi-layered and aligned particles, and forming a structure out of the network of particles. One example uses graphite powder mixed into 4-aminobenzoic acid for edge functionalization, and exfoliation occurs with sonication in a solvent. The resulting particles undergo alignment with an aligning nozzle that also dispenses the aligned particles to form a structure.

Abstract: An acrylic adhesive composition includes a first part including an aminoborane initiator and acrylate or/and methacrylate monomers, and a second part including inert microcapsules of a cure activator and acrylate monomers, wherein the microcapsules are breakable, such that when broken, the first part reacts with the second part and the acrylic adhesive begins to cure. A two-part structural adhesive includes a suspension component containing an aminoborane initiator, and microcapsules containing an encapsulated component, wherein the microcapsules are dispersed in the suspension component. A method of activating an aminoborane initiator suspension to form a structural adhesive includes adding microcapsules containing an encapsulated component, to the aminoborane initiator suspension at a predetermined ratio, and breaking the microcapsules to activate curing.
