Abstract
Abstract A composite includes a first substrate, a second substrate, and a discontinuous adhesive structure disposed intermediate the first and second substrates for securing the first and second substrates together to form a composite without significantly modifying the properties of either of the first and second substrates. The discontinuous adhesive structure is an array of substantially linear filaments or strands of an adhesive.
