Kiteboarding, wind surfing and cold water surfing are highly competitive water sport with a large number of specific needs on the mechanical properties of their equipment. Indeed, one of the central requirements of the sports is the large and inflatable kites which are used to harness the power of the wind and launch the surfer into the air at high speed. As with any product that is designed to fly, the flight characteristics (aerodynamics, weight, resistance to tear...) of theses kites are extremely important for the surfer, in terms of performance (speed, altitude of flight) and ease of use.Over the last year, the major brand manufacturers focused on one key area of the kite design: lightwind sailing. Better lightwind performance allows users to get on the water sooner, when the wind and the sea are calmer and less intimidating than high wind days. In competition, it ensures the continuity of the event even if the wind drops to low levels.This focus led industry to perform massive weight reduction on their products. Over the past decade, the average weight of a kite drop from 4,5 kgs to 3,2 kgs. However, the technical limit will be soon reached with the current sail materials used in the market. The rigors and demands of the high performance kites would no longer be fulfilled at this rate.The objective of this project is the development and the process optimization of a new material: a laminated lightweight polymer woven. The nature of the polymer will confer shock and abrasion resistance while the assembly processes will provide lightness and maneuverability to the kite. Built for the water sport, this new material could, in the future, expand his range of application in other "extreme outdoor" field like aerospace or sailing.

风筝冲浪、风帆冲浪和冷水冲浪是竞争激烈的水上运动，对设备的机械性能有大量的具体要求。事实上，这项运动的核心要求之一是大型充气风筝，用于利用风力并将冲浪者高速发射到空中。与任何设计用于飞行的产品一样，飞行特性（空气动力学，重量，抗撕裂性......）这些风筝是非常重要的冲浪者，在性能（速度，飞行高度）和易用性方面。在过去的一年里，主要的品牌制造商专注于风筝设计的一个关键领域：微风航行。更好的微风性能使用户能够更快地到达水面，当风和大海比大风天更平静，更少恐吓。在比赛中，即使风力下降到低水平，它也能确保比赛的连续性。这一重点导致行业对其产品进行大规模减重。在过去的十年里，风筝的平均重量从4.5公斤下降到3.2公斤。然而，以目前市场上使用的帆材料，技术极限将很快达到。照这样的速度，高性能风筝的严格要求将无法再得到满足。该项目的目标是开发和工艺优化一种新材料：层压轻质聚合物编织物。聚合物的性质将赋予冲击和耐磨性，而组装过程将提供轻盈和机动性的风筝。这种新材料专为水上运动而设计，未来可以在其他“极端户外”领域（如航空航天或帆船）扩大应用范围。
