Manufacturing Diaphragms for audio drivers
Manufacturing Diaphragms for audio drivers
(OP)
I am looking for any information that quantifies how to make driver diaphragms using cloth impregnated with phenolic. Anything on how to determine properties after the forming process. I know the raw phenolic properties and the cloth spec. Any good reference information would be good.

hexamethylenetetramine in ethanol -- if I remember correctly.
The properties are controlled by the heat treatment
temperature and time.
The fabric is usually acetate cellulose.
