Subject: What is "Lay-Up?"

The term "layup" is not necessarily indicative of hand layups. The term
is also used to describe composite structures that are vacuum bagged. As
John stated, it's a generic term used to describe the characteristics
of a composite.



I was also trying to shed some light on the historical origins of the use of
the word. And, buy the way, on parts that are vacuum bagged, the cloth did
not magically appear. It was placed there somehow. Most often, Laid there
by hand. Even the most precisely engineered composite parts such as those
used on aircraft components and race car bodies are laid up by hand before
going into the autoclave.
