3. Glass and Carbon Cloth
You must always use the correct cloth for the repair. Refer to the lay-up drawing of the repair area for
data about the type of cloth you must use for the repair. The lay-up drawing will tell you:
)
The correct type of cloth.
)
The fiber direction.
)
The dimensions of the layer.
Make sure that the fibers in each layer of cloth point in the direction given by the lay-up drawing. This
gives the correct strength to the laminate.
Only use sharp shears or scissors to cut the cloth to size. Make sure that the fibers in the cut cloth
point in the correct relative direction. Make sure that the fiber strands are not broken or damaged. The
cloth must be free of any damage or contamination.
4. Core Material
You must always use the correct sandwich core for the repair. Refer to the lay-up drawing of the repair
area for data about the core material that you must use.
Make sure that the core material is not damaged or contaminated.
Use a sharp knife to cut the core to the exact size for the repair. The edges of the cut must be clean
so that the core will bond correctly. You can profile the core by cutting or sanding.
Small damages of the core (diameter
#
½ inch) may be repaired by resin thickened with micro balloons
or Q-Cell.
