3. Defects sought
The defects that affect part quality and mechanical properties are found in a skin-nida-skin sandwich part:
delamination, foreign bodies, porosity in the inner and outer skins of sandwich parts;
bonding defects at nest-skin interfaces;
mesh deformations, shearing of the nida within it.
nida is short for honeycomb (see specialized articles in this treatise).
3.1 Defect terminology
Delamination is a frank decohesion between two composite plies.
Porosity refers to the presence of a large number of cavities smaller than 1 mm in diameter,...
