MANTRA CWT COMPETITION carbon fins

1) 100% IM7 carbon.
2) The material is 100% PRE-PREG carbon fiber produced using hot melt impregnation systems with tetrafunctional microhard resin.
3) 3D-Tech: Patented technology, exclusive know-how of CETMA COMPOSITES, Firing of the blades under high pressure, high temperature and vacuum, which in turn eliminates the presence of voids in the 0% carbon structure, without defects and with a constant ratio of fibers to resin throughout the blade.
4) FEM design: The design of MANTRA fins is optimized through careful finite element design (FEM). The software used enables optimal stiffness distribution to produce a multilayer blade for maximum hydrodynamic efficiency.
5) The only model: developed in collaboration with CWT bi fins world champion Michele Giurgola.
6) DRS (dynamic resonance system)-a new innovative system exclusive to CETMA COMPOSITES. This system means that the MANTRA blade is designed to resonate over a specific range of strokes. Indeed, the phenomenon of resonance is a well-known physical phenomenon that characterizes any structure. Simply put, the oscillation frequency of the leg movement overlaps with the oscillation frequency of the blade, and overall this very effectively increases the amplitude of the blade oscillation (low damping). Thanks to the engineering design, it is possible to distribute the stiffness and mass of the blade to “tune” it to a certain range of natural frequencies close to the frequencies of the leg stroke, which in turn allows the creation of the phenomenon of resonance . Thus, with little effort on the part of the swimmer, the power of the paddle stroke increases many times. This study was performed using a laser vibrometer (LDV) to perform a modal analysis to determine the mass and stiffness distributions of the blade.
7) Dimensions: width 195 mm; length from fold 702 mm; angle of inclination 27 degrees.
8) Hardness: soft, medium.
9) Color and logo: white, gray, light blue.
10) Supplied exclusively with S-WiNG cleats from CETMA COMPOSITES.
11) CETMA COMPOSITES flange: variable height flange with high efficiency.
