The composite
data frame has 9 rows and 3 columns.
Data comes from an experiment to test the strength
of a thermoplastic composite depending on the power of a laser
and speed of a tape.
data(composite)
This data frame contains the following columns:
strength
interply bond strength of the composite
laser
laser power at 40, 50 or 60W
tape
tape speed, slow=6.42 m/s, medium=13m/s and fast=27m/s
