* 100% IM7级别碳纤维
*CETMA COMPOSITES 独家专利技术，蹼片在高压、高温和高真空度环境下生产，可使组件的空隙率为 0%，使得整个蹼片拥有均匀的材质，特定的增强材料均匀分布在整个蹼片。
*FEM 设计：MANTRA 蹼片通过软件 FEM 的精确设计进行优化。 通过 FEM 软件进行设计优化刚度分布，可以使得整个蹼片在踢动状态下能获得最大流体动力效率的变形。
*签名款：与世界双鳍冠军 CWT Michele Giurgola 合作开发。
*DRS（动态共振系统）在创新且独有的 CETMA COMPOSITES 系统加持下。 DRS 意味着 MANTRA 刀片被设计成在特定的踢动频率下达到共振。  因此，当蹼片被有节奏的踢动时，用户会感觉到自己在用一个非常踢动力来达到惊人的推力。 
*意大利冠军使用Mantra脚蹼在2016年 CWT双鳍比赛项目中创造出-92 米， 2 分 55 秒的好成绩。

 

  • 100% IM7 carbon fiber.
  •  The material used is 100 % Carbon Prepreg produced with a hot melt impregnation system, using a micro-toughened tetra-functional epoxy resin.
  • 3D-Tech: Proprietary Technology, of CETMA COMPOSITES exclusive know-how, with high pressure, high temperature, and a high degree of applied vacuum, which lead to a component with 0% void level, without defects, with a uniform matrix/reinforcement ratio across the whole blade.
  •  FEM-Design: MANTRA blades are optimized through an accurate Design by means of Finite Element Softwares (FEM). The Design through FEM software allows an optimized distribution of the stiffness, with the aim to obtain a deformation ensuring the maximum hydrodynamic efficiency.
  • Signature model: developed in collaboration with the world champion CWT bi fins Michele Giurgola.
  • DRS (Dynamic Resonance System) innovative and exclusive CETMA COMPOSITES system. DRS implies that MANTRA blades were designed to reach in resonance in a definite frequency of kick. The resonance phenomenon is well noted physical phenomenon characterizing all the structures. Simplifying, when a structure is formed with a frequency close to its natural frequency the amplitude of vibration increase in a very efficient way (low damping). Operating by the distribution of the stiffness along the blade we “tuned” the blades to certain natural frequencies. So when the blade is driven, by kicking, with a certain frequency range the user feeling is a very low effort with an outrageous thrust. This study is done using a laser vibrometer (LDV) to perform a modal analysis, which helps in a stiffness distribution design of the blade.
  • Dimensions: Width 195 mm; Length from the bending angle 742 mm; bending angle 33 degrees.
