What I've done so far is research and realized my ability of working with differential calculus is lacking. But I do believe that the equations needed are:
dQ/dt = kTA dT/dx
1/kT=1/kPaper +1/ kAlu (so I can figure this out)
A = 2pi 4 inches (1/8 inches)
dQ/dt = the power supplied to...
How could I calculate how much time would be required to melt a plastic through a composite material?
Composite is .005 inches paper and .0003 inches of Aluminum
Plastic is .001 inches polyethlene with melting point of 325 F
Assume heat source is uniform across area of composite
