5. Laminating
A prescribed stack of resin impregnated cloth makes a laminate. A laminate which is used to repair
an airplane becomes an integral part of the airplane structure once the laminate has hardened and
fully cured.
You can make a laminate in place on the airplane or you can make a laminate on a work bench and
then apply the wet laminate to the airplane repair. When you make the laminate on a work bench:
)
It is easier to do.
)
It is easier to control and correct the laminating process.
)
You can make sure that the cloth layers in the stack are correct before you apply the resin.
)
You can make the repair neater.
)
You do not have to work upside down to make the laminate.
