Stone Metals Meet In Complex Aircraft Technology Poem by Terence George Craddock

cities need stone are built with concrete the iron
became steel inside buildings for railway lines
cars trains but iron was to heavy for planes first
wood steel replaced by aluminium titanium alloys
now we use a kind of stone coal how? Graphite

epoxy or carbon-fiber-reinforced polymer is
the popular choice for state-of-the-art commercial
aircraft because it is about as strong as aluminium
but half the weight and weight is an enemy of flight
resilient carbon fibers embedded in an epoxy resin

a carbon composite
materials can be stacked
in a number of efficient

strength enhancing ways
to meet various demands
of maintaining integrity

during high-speed required flight
the beauty of these carbon-fiber materials
is they are about as strong as aluminum
but half the weight weight weight weight
