T

he aerospace industry is involved
in an ongoing evolution mainly
motivated by the search for
lighter, more resistant and flexible
materials that help reduce fuel consumption and polluting gas emissions
while facilitating progress towards a
more sustainable transport model.
Aerospace manufacturers require
technologies that enable them to manufacture aircraft components through
more efficient and accurate processes
to be able to increase productivity, accelerate ramp-up and boost the profitability of the machines and equipment
they use.

Founded in 1954, Danobat is a machine tool manufacturer sited in
Elgoibar (Spain) and has over 1300 employees worldwide. The company developed a solution that contributes to boosting efficiency and
productivity while accelerating ramp-up in the manufacture of structural aircraft parts, such as wings. This technology, known as ADMP®,
has the capacity to significantly increase the production of dry-fabric
preforms when compared with prepreg processing.
veloped the Automated Dry Material
Placement (ADMP®) technology that
makes it possible to reduce the number
of machines needed to cater for future
aerospace programmes.
The company's current calculations
indicate that the use of this dry fibre
manufacturing technology very significantly reduces the production costs of
structural parts.
Due to these advantages, dry fibre
fabric-based production processes are
a very promising alternative, especially
in a background of strongly increasing
demand, where aircraft manufacturers
need to produce over 60 units per

month to meet the sector's needs without compromising quality, precision
and safety standards.
Innovation and profitability
Danobat has a solid background in the
development of technologies and solutions for the manufacture of aircraft
components using dry fibre fabrics.
The company's accumulated expertise
has culminated in its own proprietary
technology, Automated Dry Material
Placement (ADMP®), which offers
a material deposition rate 10 times
higher than that of Automated Tape
Laying (ATL) and Automated Fibre
Placement (AFP) processes used for
prepregs.

Within this context, the emergence of
dry fibre fabrics for the manufacture
of structural parts (such as aircraft
wings) and skin, stringers or spars, has
brought major benefits as compared
to current manufacturing processes
involving prepregs.
A promising alternative
Production processes based on the
use of dry fibre enable component
integration, reducing the number of
manufacturing stages required for
the part and accelerating production
times. In this respect, Danobat, a
manufacturer of machine tools and
advanced production systems, has de-
