ITALIAN ENGINEERING
CETMA COMPOSITES is a spin off company arising from the extraordinary results
achieved by Consorzio Cetma in the research activities on advanced materials collected in
numerous European and national research projects and consultancy activities.
CETMA COMPOSITES is a dynamic company specialized in developing solutions in
different fields as technical sports, aerospace and automotive.
CETMA COMPOSITES can combine robust theoretical knowledge deriving from basic
research with the experience collected in applied research for industry, and is able to
develop and produce components in composite materials with high technological content.
A team of five internationally renowned scientists with PhD in material engineering
and technicians from the advanced composite materials field work for the company.

The new carbon blades EDGE result from the study of materials engineers
who have worked for years in the design of composite components for
aerospace and automotive industries.
The engineering of the EDGE has focused on the materials used and the
innovation of technological process.
For the first time a freediving fin is designed using an engineering approach.
Several experimental tests were performed using the most sophisticated
equipment available in the company. The materials (carbon fiber/special
toughened epoxy resin) used are tested to achieve with extreme accuracy
the properties of the materials used, subsequently we proceeded with the
design aided by FEM analysis.
The activities of design, testing and manufacturing are carried out using a
laboratory for the study of composite materials among the best equipped in
the Europe.
EDGE is a guarantee of quality and excellence in Italian hi-tech products.
The EDGE blades are completely designed and manufactured in Italy, in our
laboratory.

DESIGN
The design of EDGE carbon fins was obtained through several finite element
simulations (FEM). FEM simulations were used to obtain profiles of curvature
of the blade able to improve performance in two conditions of use: swimming
with narrow kicking in such as horizontal swim and with a little larger and
more powerful kicking such as for vertical swimming (i.e. detachment from
the bottom).Numerical simulation of the mechanical behavior of the EDGE
allowed the development the first carbon blades with 3D design. The
unique design resulted in a distribution of engineered stiffness along the
carbon blades. Different portions along the blades are characterized by a
different value of young modulus in order to ensure maximum stiffness
near the shoes and progressive deformability towards the tip.

EFFICIENCY
EDGE is a balanced product terms is of thrust and in terms of efficiency.
EDGE carbon fins need less energy to produce a thrust.
This was confirmed also (but not only)by several dynamic apnea records
set in short pool course. Records with EDGE were:
•
•
200 meters in dynamic apnea with fins in short pool (25m), in indoor
Apnea Academy GIA march 14th, in Naples by Michele Giurgola;
190 meters in dynamic apnea with fins in short pool(25m), in the
Italian indoor championship march 23th, this was homologated as
new Italian record.
