delamination

He saw visible gaps in the material, areas where the layers of carbon fibre were coming apart - known as delamination.

It is known to be unreliable under pressure, and its layers are known to come apart in a process called delamination.

A known problem is that the layers of carbon fibre can separate, a process called delamination.

"Delamination at dive 80 was the beginning of the end," said Lieutenant Commander Katie Williams from USCG.

It showed areas where the carbon fibre layers had separated - a known problem called delamination - as well as wrinkles, waviness and voids within its structure.
