The structure, composition and set of properties of specimens and components, and some parameters of the process of production of a promising FML class of metallic polymers based on sheets of high-modulus (E ~ 79 GPa) alloy 1441 with reduced density (d ~2.6 g/cm3) and an optimized glued prepreg reinforced with fibers of high-strength high-modulus VMPglass are described. Results of fire and fatigue...
Working properties during production, structure, and physicomechanical properties of alloy 1441 sheets of the system Al–Cu–Mg–Li are described, making it possible to prepare thin sheets up to 0.3 mm thick by a coiled cold rolling method. Medium-strength (σu = 450 MPa) alloy 1441 sheet is distinguished by lower density (2.6 g/cm3), increased stiffness (E = 79 GPa), and it is used effectively in promising...
