Cetma - Prana

CETMA Composites PRANA Carbon Blades
Precision, innovation, and performance — redefined.
The PRANA carbon blades by CETMA Composites are engineered for freedivers and spearfishers who demand uncompromising efficiency, responsiveness, and durability. Every detail reflects advanced composite engineering and hydrodynamic expertise.
Key Features

Advanced Material Blend:

Made from 75% carbon fibre and 25% S-glass fibre — a high-resistance aeronautic-grade material known for its exceptional strength and elasticity.

100% Epoxy PRE-PREG Construction:

Built using hot-melt epoxy resin technology with micro-toughened tetra-functional resin, ensuring consistent structure, optimal fibre bonding, and superior longevity.

3D-Tech Manufacturing:

CETMA’s proprietary 3D-Tech process combines high pressure, high temperature, and deep vacuum curing — resulting in zero voids, flawless uniformity, and a perfectly balanced fibre-to-resin ratio for unmatched blade performance.

FEM-Optimized Design:

Through Finite Element Method (FEM) simulation, PRANA blades are precisely tuned for ideal stiffness distribution, achieving maximum hydrodynamic efficiency with every kick.
