Genuine Guide Gear (G3) is an independently owned and operated manufacturer of industry-leading gear for backcountry skiing and snowboarding. For 18 years, G3 has been committed to produce innovative equipment and has recently introduced significant amounts of carbon fiber composite to their product lines. The use of carbon allows for weight savings and increased stiffness, thereby improving the performance-to-weight ratio. However, materials with high stiffness values generally have low damping ability, and carbon-based skis are prone to be less forgiving in firmer snow conditions. Soft snow tends to dampen ski vibrations but icy surfaces and hard snow induce severe oscillations that affect the skier's control and balance. G3 is actively researching a methodology to predict the mechanical properties of carbon-based skis and strategies to control dynamic properties and improve damping performance at high frequencies. Ski weight is a significant issue, therefore the damping solution must not increase weight and must be cost feasible to take to production. Genuine Guide Gear has extensive expertise in the design of composite skis but has limited resources to develop its expertise on damping in carbon-reinforced composite materials. The company has requested the assistance of the Composites Research Network (CRN), at the University of British Columbia, to offer guidance in this field.

Genuine Guide Gear（G3）是一家独立拥有和经营的行业领先的齿轮制造商， 野外滑雪和滑雪板。18年来，G3一直致力于生产创新设备， 并且最近将大量的碳纤维复合材料引入到他们的产品线中。使用 碳可以减轻重量并增加刚度，从而提高性能重量比。 然而，具有高刚度值的材料通常具有低阻尼能力，并且碳基滑雪板是 在更硬的雪条件下容易变得不那么宽容。松软的雪会减弱滑雪板的震动， 硬雪会引起严重的振动，影响滑雪者的控制和平衡。 G3正在积极研究一种预测碳基滑雪板机械性能的方法， 控制动态特性和提高高频阻尼性能的策略。滑雪板重量是一个 因此，阻尼解决方案必须不增加重量，并且必须在成本上可行， 生产 Genuine Guide Gear在复合材料滑雪板的设计方面拥有丰富的专业知识，但资源有限， 发展其在碳增强复合材料阻尼方面的专业知识。该公司已要求 在不列颠哥伦比亚省大学的复合材料研究网络（CRN）的帮助下， 在这个领域的指导。
