Abstract: The present invention relates to a method for improving both adhesion between substrate and polymer layers and the durability of such composite structures; while maintaining the malleability and preferred characteristics of the original substrate. Quite unexpectedly, the application of a layer or film upon an uncured, encapsulated base substrate which has been encapsulated by the shear thinning methods of the present invention, results in superior adhesion of multiple layers when compared to conventional layering, coating or composite manufacturing methods. Moreover, the uncured or at most, semi-cured, polymer composition applied to the base substrate ensures that the substrate maintains maximum flexibility for subsequent shaping into composite articles prior to curing. The methods described herein produce multiple layer composite articles that are lighter, stronger, more flexible and utilize less material, than composite articles produced by conventional techniques.
