The materials used to build our boats and fabrications range from wood
to carbon fiber. We build some hulls from wood, foam, fiberglass and
epoxy. We use a product known as S-glass coupled with SAN, and PVC foams
to construct our Atlantic 57 hull, decks, and structure. We build
various fabrications from carbon fiber and fiberglass. Core materials
used at ACC vary from cross-linked PVC foams such as AIREX, and SAN foam
sold by the name of Core-Cell. We also use Nomex Honeycomb for
hi-strength super lightweight applications. Solid fiberglass plate and
compression tubes are used to install hardware and systems in our boats.
This product is known as G-10.
Pre-preg carbon fiber
Impregnated with a thermo-set epoxy it is the strongest
lightest material available today for composite fabrications, and yacht
ACC uses a wide variety of styles and fiber materials building yachts and custom fabrications.
ACC employs carbon for highly loaded structures and
fabrications that require great strength, stiffness, and lightweight.
Fiber Glass comes in many forms. At ACC we use E-glass, and S-glass (the hi-tech brother to E-glass.)
E-glass is general use fiberglass for composite construction.
ACC uses the stitched biaxial and unidirectional versions of this
S-glass is a much stronger and more damage tolerant version of
E-glass. S-glass is used extensively to construct military composites
due to its excellent properties. At ACC we use a unidirectional version
of S-glass. Using unidirectional fabrics allows us to apply the fibers
in the direction or path of the load, utilizing the fabric to its
fullest extent gleaning the most performance for the added cost of the
Epoxy is used to build our boats and fabrications. Epoxy, as
many people know, is the preferred plastic in FRP, or fiber reinforced
plastic—your glass boat. Epoxy is more water proof and stronger than
other boat building resins. Our resin of choice is even a step above
normal epoxies as it is a "toughened system," which increases the
matrixes' ability to endure stress better.
SAN Foam, or Core-Cell
SAN Foam, or Core-Cell as most folks know it is excellent at
energy absorption and therefore makes a great choice for hull building.
ACC uses the solid sheet version of this product and heat-forms it to
the shape of the boats we build. Solid sheet "thermoforming" is the best
method of applying foam core to a structure.
Cross-linked PVC Cores
Cross-linked PVC cores are a step above the old technology
linear PVC or Dyvinicell, as many people know the product. We use
cross-linked cores built by the Airex Corp. These foam cores are the
stiffest available, and therefore have a greater breaking strength for
the same density of SAN cores. They do however, lack the ability of SAN
cores to withstand a beating. We use PVC cores in the decks and
structure of our boats because of their great stiffness.
Nomex Honeycomb, is the big daddy of the core family. It is
lighter and stiffer than any foam available, and has a high tolerance to
heat, which makes it a great partner for thermo-set epoxies. To save
weight, ACC uses honeycomb-cored panels for the interior construction of
our Atlantic 57s as well as many custom fabrications.
Wood is an excellent boat building material when used
properly. It is light, strong, and very machinable, allowing it to be
easily shaped. Wood has a terrific ability to be bonded with epoxy. Wood
also has similar engineering properties to that of fiberglass and foam.
Combining these materials allows us to create beautiful, durable,
stiff, and strong composite structures. The woods we most like to build
with are western red cedar, mahogany, and Douglas fir.
G-10 is a pressed thermo-set fiberglass and epoxy plate, rod,
or tube material.
Used at ACC as backing plates, compression members, thru-hull drains,
and bonded in plumbing runs, G-10 is superior to many builders use of
metal components for these jobs. G-10 is paintable, tough, and bonds to
our epoxy laminate, becoming a part of the structure, not just a piece
