HiTape® Combining current
technology advantages with
increased cost effectiveness

Fig. 1: HiTape® : Innovative composite route for cost-effective primary aircraft structures

for many years, and some are even
used now for primary aircraft structures on a small scale. Hexcel has been
a leader in the development of this
technology through a large number of qualifications for HexForce®
reinforcements and HexFlow® RTM6
resin. Woven fabrics and non-crimp
fabrics (NCF), when combined with
the appropriate resin infusion and
injection process, can provide a positive performance/cost balance. Cost
savings have been demonstrated in
part design, function integration, less
assembly time, and potentially fewer
finishing operations.
However, these materials do not fully
meet the mechanical performance re-

quirements or the quality standards of
primary structures due to the manual
lay-up process of the dry preform. The
emerging automated “pick and place”
of woven or NCF materials can only
be seen as a step toward the ultimate
automated solution, combining a
scrap-free process with optimum
design possibilities.
Despite the interest in higher deposition rates, major drawbacks of current
NCF materials include a lack of design
freedom, ply stop minimum thickness, high scrap levels, inadequate
mechanical performance (in particular
toughness) and microcracking after
hygrothermal ageing.

Fig. 2: HiTape® : Similar performance to latest generation prepreg

Hexcel’s innovative proposal is to
combine the benefits of automation
and the cost effectiveness of infusion/
injection technologies with the high
performance of latest-generation prepreg materials.
The new proposal is the missing link
between interesting but incomplete
current LCM materials and latest-generation prepregs in term of performance-cost ratios.
Performance in composites comes
from straight, perfectly aligned fibres;
HiTape® is therefore a unidirectional
tape. Made from Hexcel’s HexTow®
carbon fibre and combined with HexFlow® infusion resin, HiTape® matches
the performance of the latest-generation UD prepregs.
While offering the same overall inplane mechanical performance level
as state-of-the-art prepreg materials
thanks to the equivalent 60% fibre
volume content achieved by vacuum
infusion, another major innovation of
HiTape® is to improve the toughness
of current composites made by LCM
technologies.
With standard dry unidirectional tape,
through-the-thickness resin permeability is a clear limitation for thick
parts. Thanks to proprietary technology, HiTape® is available in different
