Cetma blades Mantra Diamond Special Edition Soft Black
Cetma blades Mantra Diamond Special Edition Soft Black. CETMA COMPOSITES never ceases to amaze with its countless creations, we present a unique Fin in the world, made for those who do not want to go unnoticed. Mantra Limited Edition has 6 XIRIUS crystals from Swarovski and mirror logos that convey an exceptional brilliance, projecting iridescent colors when illuminated by light and guaranteeing the performance of the MANTRA fin. 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.
