ABSTRACT:
Fatigue- and flutter- resistant laminate, suitable for use as constructional material in aviation, particularly in the construction of wings. It comprises (I) a laminated cover having a constant thickness and consisting of at least two metal plates firmly interbonded by an intermediate resinous layer reinforced with continuous strands, a substantial proportion of which extends mutually parallel in at least one direction, and (II) a substrate which is firmaly bonded thereto, and comprises at least one metallic support plate having a tapering thickness. (I) and (II) may be interbonded by means of an optionally fiber-reinforced resin. (I) may be present on both sides of (II). Preferably, the minimum thickness of (II) is at least equal to the thickness of the metal plates present in (I). More particularly, the thickness of (II), tapers from 11 to 1 mm (over a length of at most 20 m).
