<p>The snowboard core is made from a series of lengthwise strips (7-16) made either from wood, synthetic foam or foam with fiber filling. The strips are not more than 25 mm wide, are stuck together, and the number of strips and proportions of different materials is selected to give the board various properties, e.g. tonic and damping. The proportions of different materials are, e.g., 40% synthetic foam, 40% wood and 20% fiber-filled synthetic foam.</p> |
