Fiber-metal laminate stringer for use in aircraft or spacecraft, has synthetic fiber layers produced from Zylon fibers, and provided between metallic layers, and straight side portions and middle region merge with one another

摘要

The stringer (ST1) has a set of synthetic fiber layers (S2, S4, S6), produced partially from Zylon fibers, and provided between a set of metallic layers (S1, S3, S5, S7), where the stringer is in Z shape. Straight side portions (SB1, SB2) and a middle region (MB) are merged with one another by using arcs of a circle. The set of metallic layers are produced from aluminum or an aluminum compound or an aluminum alloy, where the stringer has a modulus of elasticity of between 90 and 100 giga pascals.
