Honeycomb core failure mechanism of CFRP/Nomex sandwich panel under multi-angle impact of hail ice

, 2021
The rudder of an airplane is fabricated as a sandwich panel and can potentially be damaged by hail ice. The dynamic responses of a CFRP/Nomex sandwich panel with barely any visible core damage under multi-angle impact of an ice sphere at various ...

Design and characterization of a multilayered hybrid cored-sandwich panel stiffened by thin-walled lattice structure

, 2021
Low-density polyurethane (PU) foams have been commonly used for some structural purposes in marine applications. However, they have not been exploited as a structural core because of damage tolerance and durability concerns.

Sandwich acoustic panel

The Journal of the Acoustical Society of America, 2004
An acoustic panel with several degrees of freedom comprises a resistive layer (14), a compartmentalized structure (16) formed from at least two superposed compartmentalized layers (18) and a back reflector (17), starting from an outside face facing an incident acoustic wave.

Incremental Forming of Sandwich Panels

Journal of Materials Processing Technology, 2007
This paper presents a first investigation of the applicability of incremental sheet forming (ISF) to sandwich panels. Two initial tests on various sandwich panel designs established that sandwich panels which are ductile and incompressible are the most suitable for the process.
