Overnight I remembered a couple other well known composites: When I was a boy,
sheetrock had not been invented, at least all the houses I saw built had oldtimers
with a big flat tub mixing slow setting plaster of paris, with sand for bulk, and cows hair
for linear element.
Then there was the tarred paper for roofing underlayment.
The first raincoats with liquid rubber applied to fabric.
The balloon type inflated buildings.
The fabric on early airplanes.
