1) 100% IM7 carbon fiber blade.
2) The material is PRE-PREG 100% Carbon obtained with hot melt impregnation systems with tetra-functional resin.
3) 3D-Tech: Proprietary technology, exclusive know-how of CETMA COMPOSITES, high pressure, high temperature and vacuum, which implies a component with 0% voids, free of defects, and with a constant fiber / resin ratio over the entire shovel.
4) FEM Design: MANTRA's design is optimized through a careful finite element design (FEM). The software used makes it possible to ensure an optimal distribution of stiffness in order to reproduce a deformation of the blade which guarantees maximum hydrodynamic performance.
5) Signature model: Developed in collaboration with the CWT bi fins world champion Michele Giurgola;
6) DRS (Dynamic Resonance System) new innovative system exclusive of CETMA COMPOSITES. This system implies that the MANTRA blade has been designed to resonate in a certain range of kicking frequencies. The resonance phenomenon, in fact, is a well-known physical phenomenon that characterizes any structure. Simplifying, we can say that when a structure is forced with a frequency close to its natural frequency, the amplitude of the vibrations increases in a very efficient way (low damping). Through the engineering design it was possible to distribute the stiffness and mass of the blade in such a way as to “tune” the blade in a certain range of natural frequencies close to those of the kicking frequency, thus allowing the phenomenon of resonance. The final user feedback is therefore a very low effort corresponding to an incredible propulsion. This study is done using a laser vibrometer (LDV) to perform a modal analysis, which served to establish the mass and stiffness distribution of the blade.
7) Size: Width 195mm; Length from the fold 742 mm; inclination angle 33 degrees.
8) Stiffness: super soft (XS), soft (S), medium (M).
9) Colors: White, Gold, Magenta.
10) Shoe attachment: CETMA COMPOSITES, Mares and Pathos.
11) Water rail: High performance variable height water rails.
12) Warranty: 2 years on carbon parts;
13) Results achieved: ITALIAN CHAMPION 2016 CWT bi-fins with -92 meters in 2 minutes and 55 seconds.
