Which of these methods may be used to inspect fiberglass/honeycomb structures for entrapped water? 1. acoustic emission monitoring. 2. x-ray. 3. backlighting.

X-ray and Backlighting

Explanation:

Fiberglass/honeycomb structures can be possibly inspected for entrapped water either by Backlighting or X-ray method.

The Backlighting method of inspection is carried out by removing all the surface paints and beaming a strong light on just one side of the panel whilst examining from the other side for any dark areas that would give an indication of entrapped water.

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.
