Cetma Mantra Carbon Freedive Fins

      The CETMA MANTRA Carbon Fin Blade has been specifically engineered for CETMA S-Wing Footpockets. The S-Wing Footpockets are sold separately and also available for purchase. Carbon Fiber Blades MANTRA key features:1) 100% IM7 carbon fibre.2) The material used is 100 % Carbon Prepreg produced with hot melt impregnation system, using a micro-toughened tetra-functional epoxy resin. 3) 3D-Tech: Proprietary Technology, of CETMA COMPOSITES exclusive know-how, with high pressure, high temperature and 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. 4) FEM Design: MANTRA blades are optimized trough an accurate Design by means of Finite Element Softwares (FEM). The Design trough FEM software allows an optimized distribution of the stiffness, with the aim to obtain a deformation ensuring the maximum hydrodynamic efficiency.5) Signature model: developed in collaboration with the wo
