PLY DROPS IN COMPOSITE SANDWICH PANELS

摘要

A structural panel for an aircraft nacelle may comprise a first skin, a second skin, and a core sandwiched between them. One of the skins may comprise regions of different thicknesses. The regions of different thicknesses may be separated by a ramp, in which the number of composite plies in the first skin varies. A slope of the ramp may vary across the ramp to prevent disbonding of the core from the skin at the base of the ramp.

1. A structural panel for an aircraft nacelle comprising:
a core; and a first skin coupled to the core, wherein the first skin comprises a first region having a first thickness, a second region having a second thickness greater than the first thickness, and a ramp between the first region and the second region, wherein a first slope at a first point of the ramp is greater than a second slope at a second point of the ramp.
