NTPT Richard Mille watch - Case history

from Huntsman
Advanced
Materials meet
criteria for
manufacturing
ultra-thin
prepreg tapes
Huntsman Advanced Materials has
been supporting Swiss pre-impregnated
materials specialist North Thin Ply
Technology (NTPT) to produce ultra-thin
prepreg components on a Richard Mille
luxury watch case.
Founded in 2009, NTPT designs and
manufactures ultra-thin prepregs for high
performance composites applications.
From its main facility in Switzerland, the
company’s 25-strong team focuses on the
research and development of prototypes
and small series production.
Special techniques for
ultra-thin prepregs
The business offers unique spread tow
and associated prepregging techniques to
manufacture uni-directional prepreg tapes
processed with thermoset resins, which
can be as thin as a third of a human hair
in diameter. To facilitate their handling,
the company has also developed an
automated tape laying system. NTPT’s
technology package is completed with
simulation software which enables efficient
parts designs, taking advantage of the
uniqueness of ThinPregs®
.
Based on its track record and expertise
in formulating specialty components
for impregnation systems and its
understanding of the specific requirements
of ultra-thin prepreg processing, NTPT
decided to work with Huntsman on the
watch case project.
From components to high
value prepreg composites
The watch cases are made from thick
blocks of 400 thin ply of ThinPreg®
carbon
fibre uni-directional tape, pre-impregnated
with an epoxy resin matrix system based
on building blocks (resin, toughener and
hardener) selected with Huntsman’s
support. Because of the ultra-thin interply
thickness, the autoclave cured block can
be considered as a one phase material
which is machinable (drillable, millable) in
the same way as metal.
