1) Blade 75% carbon fiber and 25% S-glass (high-strength glass of aeronautical origin). 2) The materials are: PRE-PREG 100% Carbon and PREPREG S-Glass obtained with hot melt impregnation systems with tetra-functional resin. 3) 3D-Tech: Proprietary technology, exclusive know-how of CETMA COMPOSITES, at high pressure, high temperature and under vacuum, which implies a component with 0% voids and free from defects. 4) FEM Design: The PRANA design is optimized through careful finite element design (FEM). The software used allows us to ensure an optimal distribution of stiffness in order to reproduce a blade deformation that guarantees maximum hydrodynamic performance. 5) Dimensions: Width 185; Length from bend 667 mm; inclination angle 33 degrees. 6) Stiffness: soft (S), medium (M). 7) Colors: Yellow, Orange, Red. 8) Foot pocket attachment: CETMA COMPOSITES, Mares, and Pathos. 9) Water rail: CETMA COMPOSITES high-performance variable-height water rails. 10) Warranty: 2 years on carbon parts; 5 years if equipped with a CETMA COMPOSITES foot pocket.
