Focus
Graphene by
application sector:
- Composites
- Paints, coatings, and inks
- Energy storage and
harvesting
- Electronics
- Catalysts
- Tyres
- Others
Future technology roadmap followed by Applied Graphene Materials for a " greener " world
- GNP particle size can also be
important. Particle size can
have a signifi cant impact if
resin mixes are to be fi ltered
for infusion; smaller platelets
may well be needed for
such processing methods.
Similarly, the fi bre preform
architecture itself may fi lter
such included particulates, so
particle size can be important
here as well. If GNPs are to be
added to a fi bre size or used
to coat a preform, the particle
size of the graphene needs to
be considered relative to the
diameter of the fi bre being
coated.
- The functionality of
the material can have
a determining eff ect on
dispersibility through to the
degree of bonding to the host
matrix. Th is in turn may aff ect
mechanical performance.
- The dispersibility of diff erent
types of graphene with
loading level can also have
a profound eff ect on the
viscosity of the host media, so
care must be taken in material
selection considerations, in
order to maintain mixing and
processibility practicalities.

Benefi ts
One of the key benefi ts in
carbon fi bre composites seen
consistently with the addition
of graphene nano-platelets is
in Mode 1 fracture toughness.
Hereby, the longevity of a
composite matrix can be
increased signifi cantly through
the eff ective use of low loading
levels of well-dispersed GNPs
throughout the matrix.
Prepreg materials are available
where the matrix fracture toughness
has been enhanced through
the eff ective use of a graphene
dispersion additive to the resin
mix.
Similarly, end users such as Infi
nite Composite Technologies
Inc. have made well-documented
good use of GNPs introduced
through dispersion additives.
In their case, the pressure cycling
from liquid gases in Type V
pressure vessels greatly benefi ts
from the use of graphene in such
systems.
Toughness improvements also
benefi t applications such as
prepregs used in extreme sports
goods.
Th e barrier performance of
graphene in resin matrix systems
jec composites magazine / N°
is well documented from AGM's
work in coatings applications.
Signifi cant improvements in the
diff usion control of corrosive
species in coatings can be dramatically
altered with very low
loadings
platelets.
of
high-surface-area
Th ere is litt le reason in principle
why the same performance cannot
be achieved in a composite
matrix system.
Vapour transmission rates can
potentially be reduced through
a matrix of, for example, a composite
chemical storage tank, a
carbon pressure vessel or other
composite structures susceptible
to adverse moisture conditions
and weathering. Wind turbine
blades come to mind here.
Conductivity can potentially be
enhanced with GNPs used in the
matrix material. However, care
should be taken in this instance
to balance the higher loading
level needs for either electrical
or thermal conductivity and the
lower loading level limits for
mechanical performance.
Conclusions
GNPs off er a great potential for
materials engineers to enhance
147 September - October 2022
the performance of their composite
systems. From a range of
att ributes imparted through the
use of graphene nano-platelets
as an additive, the possibilities
align well with the appeal of
composites themselves for
an ever-increasing breadth of
applications.
Care needs to be taken to select
the correct type of graphene for
the application in mind. Critical
to success
of the graphene nano-material
in question into the material to
achieve a well-ordered dispersion
throughout the matrix. In this
way, maximum eff ectiveness can
be achieved in use of the material.
Finally, the materials and process
(M&P) engineer must bear in
mind the potential eff ect that
a high-surface-area material
addition can have on the process
viscosity of the material being
added to, and the downstream
processibility of some systems,
such as vacuum infusion of
preforms.
Bearing all these considerations
in mind, successful outcomes
continue to be achieved with
this new and interesting class
of additives for composites,
coatings and beyond.
