SECTION 2
BILL
OF MATERIAL - Defined and Explained
2.1 Fiberglass
There are three different types of fiberglass reinforcements:
a) Mat b) Cloth c)
Woven Roving
Depending on the "Lamination Schedule" or area of construction, these three
types of fiberglass are combined.
a) The fiber glass MAT is a very strong material and is
designated by the approximate weight per square foot: 3.0 oz.
mat, for example. However, "squeegeeing and brushing" of the
wet fitted material may cause it to tear or ball up.
b) The CLOTH, always used in conjunction with mat, is most
satisfactory for a finished surface. The designation for cloth
refers to the approximate weight per square yard: 7-1/2 oz.
cloth, for example.
c) WOVEN ROVING is used for structural purposes in conjunction with
mat. This is the material that provides maximum strength and
rigidness to a fiberglass laminate. Without woven roving a
laminate of fiber glass cloth and mat would bend and flex. Woven
roving, like mat, is designated in approximate weight per square
yard: 24 oz. woven roving, for example.
NOTE: A detailed explanation concerning the nature of
fiber glass is covered in Section 6 on fiber glass
repair.
2.2 Resins and Catalysts
The resin used to solidify the fiber glass in all Sailcrafter Yachts is a
polyester resin. Use only polyester resins when applying fiber glass to your
Sailcrafter Yacht - other types of resin will not be compatible.
