Carbon fibers are used as a cloth in the snowboard core to give better response . Carbon fibers are ideal for use in snowboards, because they provide the highest specific module of toughness and strength of all reinforcing fibers (Callister, 1997) . Carbon fibers are also not subject to weather changes, and they retain high tensile strength and high strength.
Kevlar used in the core reduces weight, vibration, and dampening. It has good strength (Snowboards, 1999). Kevlar was created in the early seventies. It is known best for its ability to be very tough, impact resistant, and resistant to creep failure (Callister, 1997) .
The base of a snowboard is made of polietilene. In the snowboard industry it is often referred to as Ptex. Polietilene has a porous structure that allows it to hold wax. Polietilene on a snowboard base is either extruded or sintered. Extruded polietilene bases are cheaper than sintered bases. Extruded bases do not give you as much absorption of wax compared to sintered bases (How a Snowboard, 1999). A higher molecular weight causes the sintered base to absorb larger amounts of wax (How a Snowboard, 1999). Sintered bases are much harder than extruded bases and are more durable. Sintered bases are more expensive and much better adapted for the racing snowboards (How a Snowboard, 1999). Sometimes companies use graphite or fluorine to improve the glide of snowboards (Donek, 1999). Some manufacturers are using graphite in their snowboard bases. Traditional snowboards with sintered bases cannot even utilize the speed they produce effectively (Identity, 1999).

The Sceince of a Board (Core1)
Before reading this remeber all information might change with differant board design. Im a student that wrote this for a class not in the industry. If any of this information is incorrect and you can prove it tell me and ill do my best to improve it. Also anyone is buying a board keep some of this information in mind.

Snowboards consist of many materials that produce a stable and safe riding surface. It is important for manufactures to analyze and test the materials to ensure that the snowboard performs effectively and safely.
There are three basic constructions when producing snowboards they include cap, rim, and laminated constructions. Cap construction is when the top material covers the deck and the side walls of the snowboard. Cap snowboards get their strength from their arched edge. Rim construction is when polyurethane is injected around the wood core. Laminated boards are the most common. Laminated snowboards consist of sheets of materials stacked and glued together. (Snowboarding, 1999)
The core of a snowboard can be made of foam, wood, or microcell. The core of the snowboard affects flexibility and weight. Wood cores are the traditional cores for snowboards. Wood makes a good core because it dampens vibration. Wood’s anistrophic characteristics transmit the vibration along the length of the snowboard, so it decreases the ability of snow to stick to the bottom, and improves the glide (Snowboarding, 1999). Poplar or aspen are the woods of choice (Identity, 1999).
Foam cores are usually made of polyurethane. Good manufacturers produce polyurethane core snowboards that are just as durable as wood core snowboards but are lighter and do not compress. A sign of a good snowboard is one that has the core molded to the heart of the snowboard (Snowboarding, 1999). Some companies inject the foam between the topsheet and base material to form a core. These snowboards lack chamber and sometimes have pockets in them which lead to major system failure in the snowboards operation (Rossignol, 1999).
Rossignol produces a microcell core. The material Rossignol uses is a composite material. Rossignol claims their material provides constant flex no matter what the weather and dampens vibration (Rossignol, 1999).
Some boards have reinforced cores of metal, carbon fibers, kevlar, or fiberglass. Metal and fiberglass are used around the core of the snowboard. There are three reasons why fiberglass has become so popular in the snowboard industry. Fiberglass can easily be taken from a liquid state and made into strong fibers, is readily available to be made into glass reinforced plastic, and is very strong when imbedded into a matrix (Callister, 1997). Secondly fiberglass fibers in a matrix provide high fracture toughness. The third reason for the popularity of fiberglass is that the matrix separates the fibers to prevent the formation of little cracks which can run from fiber to fiber (Callister, 1997). Fibers in a matrix are also protected from surface, chemical, and environmental damage.

Black vs Neon Green
Recently I preformed a detailed research project about how the color of your snowboard can effect its performance. I did my best to ride every color of snowboard, and compiled a large amount of interesting information.

The first wooden parabolic object that I rode was pearl white. This board was the smoothest of all the boards I had riden, but had one major flaw. It tended to sparkle, and reflect the light of the sun, causing the rider to become temporarily blinded. My riding was effected drastically because I had trouble viewing the approaching terrain.

The second board I had the chance to ride was Jet Black. The board was as fast as a fighter plane, but seemed to have a much larger mass than its competitors. Enormus effort was needed to redirect the large mass, which made spinning almost imposible.

I rode almost every color of the rainbow, causing myself to have a large knowedge of the performance of each shade. Each color seemed to have an advantage, as well as a disadvantage. No one board seemed to be better than the other because all of their advantages crossed out with there disadvantages.

In conclusion, I have found that there is only one sensible board to ride. The 2000 Ross Powers' Pro model by Burton incorperates every color ever amaginable. And so, must be the best performing board on the market.

Be original!
I don't get it! Everybody just uploading some sh*t! And nobody owns that sh*t! There is just some of us that uploaded just our photos... original photos!

Don't u know how to read? UPLOAD ONLY OWN MATERIAL! All of you who uploading sh*t that is not yours and sh*t that is not about snowboarding just please go somewhere else!!! You suck....

Upload tricks that you do! Upload photos of yourself not photos of Terje Hakonsen and Ricky Martin and pictures about space! I asume that this is page about snowboarding not about 3D graphic...

And for the end of storie! Be realistic at ranking! Don't give to other people score 1 because you wanna be the 1st one! If the photo is good and ORIGINAL give it score 5!!!

TRIP OUT WEST
This was the best place ever out west.
I went to lac loise for 3 days then heded over to BC to go to Fernie
Fernie was the best place ever
It had the most powder and it constanly snowed
There skate park was amazing and there bowls we so fun
The bowls had so much powder they had to put explosives so it would prevent a avalance
Anyways Fernie was tha best place ive ever been in my life and i hope to ride there some day again
