As a general rule there should be a bond wherever two ponels touch, or wherever they
close on important points. It
is
usually possible to check these bonds both visually
and physically for fractures or breaks. Ascertain the cause of
damage and the
direction of impact and examine all panels or bonds which
may have been affected.
A front end impact, for example, may easily cause the bonds ot the bulkhead to split
without the defect being easily visible.
To facilitate a closer examination it may be necessary to remove parts and components
to determine the extent of the damage. When
determining the size of the replacement
pariels to be ordered, make sure the new panels, when cut-in, will be attached to
firm GFRP material; avoid badly
crazed areas arid badly burnt areas.
Fire damage
is
the most difficult to assess but generally only the obviously burnt or
charred sections will
need to be replaced or reinforced.
