This book covers the theory of the strength of laminated and reinforced structures made of polymer materials with regard to the changeability of physico-chemical properties is examined. It presents an experimental-theoretical method on the definition of physico-mechanical properties of polymers composite materials and polymerized bundles made of fibers with emphasis on the changes of physico-chemical properties of the materials. With mathematical strictness, the experimental and theoretical studies presented here will aid in the development of reliable methods and new practices of analyzing...
