IMPORTANT!
To
ensure good mat contour fit, mat density of the first
layers must not exceed 1075 g/m
2
(31.7 oz/yd
2
). Alter-
native directed fiber mats (not CSM) of density less
than 1500 g/m
2
(44.3 oz/yd
2
) may be used in the other
layers as long as minimum requirements for number of
layers, total density and total mat thickness are met.
IMPORTANT!
Secondary bondings must be avoided for the lamina-
tion, see General page 51.
Grinding
Grind a wedge in the hull so that the hull thickness
drops off to the insert. Slope, approx: 1:12. Make the
lamination fill up the recession, following the steps
below.
The bonding surfaces of the pre-molded ring must be
lightly grinded (even if it is already grinded when sup-
plied from Volvo Penta) and cleaned from surface con-
taminates before it is used.
Mat contour fit
Mats must strictly fit the contour of insert. Extend mats
up to top of insert.
First layer
Place mats around the inserts, that are extended (A)
100 mm (4”) from insert transition onto the hull. A mat
overlap of minimum 50 mm (2”) on the insert must be
applied.
NOTICE! Transom thickness requirement, same as
bottom, applies 600 mm (24”) from bottom and up. It
can therefore be useful to extend aft insert mats.
