BASICS - MATERIALS & CONSTRUCTION
This article will give you general ideas of how Snowboards
are Constructed and what they are made of. Although every Snowboard
manufacturer has their own special trick when it comes to making
their Snowboards, this section will discuss the basic formula on
How to Make a Snowboard.
Snowboard Construction
There are some Basic Components that go into
the Construction of every Snowboard. Each Snowboard has a base,
an outer edge, a core, and a topsheet. A good quality Snowboard
will be constructed like a Ski - it has metal edges and a P-tex
base. There are generally Two Types of Snowboard Construction:
the Capped Snowboards and the Traditional Sandwich Construction.
In
Capped Snowboards, the top sheet (outer skin) is pinched over
the sides of the snowboard meeting the steel edge. On the other
hand, the top sheet on Traditional Sandwich Construction is
flat, with the armor plating on the sides provided by separate
sidewalls.
Each Type of Snowboard is similarly constructed with exception
to some tooling modifications. Some designers say that Cap Construction
enhances edge hold on hard snow and generally improves board
responsiveness. Others claim that caps are harder to repair if
you damage the sidewall. Both types have their merits, keep in
mind though that what really matters is the materials under the
skin.
What's in a Board?
The eight main materials in a snowboard are the:
- Topsheet with printed graphic
- Fiber glass or epoxy
- Wood or foam core
- Steel inserts
- Plastic base, (p-tex)
- Metal edges
- Resin Sytsem (glue)
- Rubber Foil
Layers of Snowboard
A Snowboard is similar to a sandwich that is made up of many
layers. What follows are the components of a snowboard from
top to bottom:
- The top layer of a Snowboard is a protective plastic layer
called a "topsheet." The topsheet does not only protect
the insides of the Snowboard from damage and exposure to ultra-violet
rays, it also provides a good surface for graphics. Although
the material used for the topsheet can vary, there are basically
two types of topsheets - the glossy and matte. Glossy topsheets
usually come with sublimated graphics. On the other hand, matte
topsheets in general have screened-on graphics.
Inside the topsheet is a layer of "fiberglass". This
fiberglass lies on top of the core.
The Snowboard's "core", which lies beneath the fiberglass,
is what the rest of the board is wrapped around with. The core
makes up most of the thickness of the Snowboard. This is usually
made of wood foam, honeycomb panels, or a combination of wood
and other composite materials, with sets of metal inserts needed
to mount bindings.
- Cores made from honeycomb are lightweight
and are surprisingly strong. With a wood core, you can be assured
of a smooth response and lively flex from the board. Foam cores,
in contrast, can sometimes loose their flex.
- Next is another
layer of fiberglass, "fiberglass reinforced
plastic" in particular. This provides stiffness and strength
to the Snowboard.
- Following the fiberglass are steel edges.
These edges surround the P-tex of the Snowboard, allowing the
board to dig into the snow while turning. There are actually
Two Kinds of Edges: partial steel edges that run only along
the sides of the board, ending at the nose and tail, and edges
that wrap all the way around both ends of the board.
- On the
bottom is a layer of ultra high molecular weight polyethylene
material commonly called "P-Tex." This is a dense,
abrasion resistant plastic with low friction properties which
provides the slippery surface that makes the Snowboard slide
on Snow Surface. To keep your Snowboard running fast throughout
the winter, you need to add wax to this base layer.
There are basically Three Different Types of Snowboard Bases
- extruded, sintered, and graphite. Extruded bases are long
lasting and easy to repair. However, they are the slowest type
of base, and they hold less wax than the other types of bases.
A Sintered base is superior to the extruded base since it's
more durable, faster, and can hold wax better. Then again,
it's more expensive and difficult to repair. The graphite base,
on the other hand, is the fastest type of Snowboard base and
has a higher capacity to hold Wax. This Type of Snowboard Bases
are always deep black and are mostly found on fast racing boards.
If you're looking for high performance, opt for a Snowboard
with a sintered base. Then again, if you're on a tight budget,
an extruded model will do.
