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.
This data frame contains the following columns:
interply bond strength of the composite
laser power at 40, 50 or 60W
tape speed, slow=6.42 m/s, medium=13m/s and fast=27m/s
