Yesterday, Xiao Bian gave everyone the popular science about the parameters of the veneer sheet. I believe everyone has their own understanding of the knowledge and selection of the snowboard. The pattern is not the most important, and the core material is the most critical factor in determining the performance of a snowboard. How are these materials made and what are the differences? Let's go and see it together. The wood of the snowboard core is usually not cut from the whole piece of wood. The whole piece of wood cuts the plate. Due to the problem of distribution of wood texture, the performance of the snowboard core is inconsistent. This is because the core of the plate is very thin. There is an uneven distribution of the entire wood, it is easy to affect the performance of the snowboard, so now the board is usually used wood material, or called splicing material, is a multilayer s The following figure. Of course, this is also caused by the modern snowboarding process. The modern splicing process is very mature, and the glue performance is also very good. The earliest snowboard cores are not so stressful at that time. It is also common to pick up a board core. The early source of wood is not as cherished as it is today. Modern technology also requires environmental protection and renewable sustainability. The early days were simple and crude. Of course, this is also caused by the modern snowboarding process.

The early source of wood is not as cherished as it is today. Modern technology also requires environmental protection and renewable sustainability. The early days were simple and crude. The commonly used wood is: Birch, birch: compact structure, elasticity, mechanical strength, hardness slightly softer than poplar, heavy weight, is a very good core material, usually combined with poplar, poplar as a composite core and control the weight. Poplar, poplar: This is the core material that many brands will choose, characterized by strong toughness, good elasticity, the disadvantage is that the weight is slightly heavier. Individual snowboards will use poplar wood in private forests. The growth year will be long, the fibers will be thicker and longer, and the effect will be better. Aspen, aspen, light poplar: light poplar, low density poplar, usually poplar or fast-growing poplar wood, lighter in texture than poplar, lighter in toughness, generally used to replace poplar or some poplar reduce weight. Paulownia, paulownia wood, paulownia: loose texture, porous, often used as a shock absorber with the main material, or with poplar can reduce the overall weight. Beech, eucalyptus: Beech, dense in texture, and of high hardness, and is usually used for local reinforcements in conjunction with the main material, such as reinforcement at the anchorage, or as a stringer running through the snowboard, increasing the explosive power of the snowboard. Ash, white wax: Hard ash, the domestic furniture line is called Ash. The foreign ash board cores are generally used only in some types of hand-made racing board sports. Hard waxes are hardwoods. This kind of hardwood is not suitable for use in freestyle snowboards. Even if it is some racing board competitions, Yangpak core is used more. The selection of white wax is all handcrafted snowboards, which are difficult to process and the wood selection is also strict. Balsa, balsa wood, balsa wood, also known as airplane wood, are often used as models. The wooden structure is granular, light and brittle, and the wood is very soft. It is used together with other wood and can effectively reduce weight. . Sustainable Natural Fiber: SNF, this is an overall concept, is a sustainable natural fiber that some brand snowboards put forward when emphasizing environmental protection concept. Snowboard wood cores with this logo or concept are all sustainable recycled timber used. The unspoken rules in the industry are that old stocks of snowboards can be recycled, throw the cores, and re-glue the boards to become new sales. So some of the new snowboards we encountered, if they are new models or new designs, may not be recycled old models reprocessing, but there is no new upgrades, it is likely that the old models reattached after the skin. Bamboo and bamboo fiber: Bamboo fiber is artificially processed. Through high-temperature and high-pressure, the sugar-separated bamboo material is pressed into a plate. Therefore, bamboo fiber is not a complete natural material. The use of bamboo is usually similar to that of eucalyptus, as a rib pre-set on the middle of the core, or on the edge of the core and on the edge of the core (as noted by the Whitegold Brandink, which deals with siding. Use bamboo fiber for siding and board edges). The use of bamboo fiber in the siding part can be used instead of P-Tex to increase the strength and also has a good shock absorption effect. The use of bamboo in the edge part of the board can increase the energy transfer at the edge of the board, as is the case for the double board brand Stöckli. However, bamboo also has its disadvantages. Excessive use of bamboo, such as pure bamboo cores, can cause snowboards to be "squeaky," and elasticity is too fast and too fierce, not soft and not well controlled. So the works that will fail again, such as Loaded's first snowboard gave me the impression that, like the snowboard made out of the bamboo fiber floor, the foot is tight and the person collapses. Inside the Yes snowboard, some flagship models will also use two carbon fiber wrapped bars (PowerDrive Rail) embedded in the end of the plate and parallel to the side edge arc, increasing stable snow catching ability and superior rebound. explosive force. KOROYD : It adopts a compact tubular body with a common compaction and a vertical micro-welding combination, which has a good energy absorption function. KOROYD is 70% lighter than standard balsa wood. However, it is still very strong and has good flexibility. The light material of the core structure can effectively enhance the fluency experience when sliding, and at the same time effectively improve the shock absorption performance of the snowboard. This technology is only used in NITRO's Ultimate - it has a sense of sensitivity and control. However, KOROYD material is similar to bamboo fiber and belongs to purely synthetic material. It is not as soft and layered as natural wood, but it is very direct. Therefore, KOROYD is often mixed with wood, and the feel of KOROYD's board is rather stiff. Therefore, a double board like Head uses KOROYD material and it is used in combination with a wood core.
