What is Vltelmat :
Vitelmat™ is a high performance non-woven
fabric developed specifically for the Fibre
Reinforced Plastics (FRP) industry.
Designed with a micro-cellular structure, which provides volume
with a very low weight and voids that allow easy absorption of
resin, Vitelmat™ is ideal for use as a core material in FRP
sandwich constructions.
The thermoplastic micro-spheres incorporated in Vitelmat™
are resistant to high temperatures (>170°c) and high pressure.
When these micro-spheres are saturated with resin and
moulded as desired they
gain rigidity.
Laminates made with Vitelmat™ have a high impact tolerance,
are stiffer, lighter, and easier to manufacture and have an
excellent surface finish.
Vitelmat™ is supplied as an industry-standard 1m width and
comes in 2mm, 3mm, 4mm and 5mm (depth) formats. A 1.27m
width is available on special orders.

Advantages of using Vrtelmat :
|
|
| |
|
Easy to use : The application does not require sophisticated equipment
or specific tooling.
Versatile : Vitelmat™ adjusts to virtually any mould shape, making it
quick and practical. Can be used as both a core material
and a superior thermal and acoustic insulator.
Lightweight :Provides increased thickness with low weight.
Shear strength : The fabric will not be damaged when applied with a
conventional laminating roller.
Rigidity : When used as a core, helps build up thicker laminates
with a very high rigidity.
Lower production costs : Less down-time required, as fewer layers of resin and
fibreglass mat are required. An average of 20% less resin
consumption in a laminate may be achieved. VOC emissions
are also reduced. Overall, the costs savings for the FRP
industry can be quite significant.

Vitelmat™ processing :
Using a trim knife or scissors, simply cut Vitelmat™ to fit the
mould. Any adjacent pieces of Vitelmat™ should be butt-jointed
with minimal gaps, rather than overlapped, to ensure a smooth,
ridge-free area.
Apply a layer of fibreglass to the laminate surface, roll it out
and then apply the resin (hand or spray). Pre-wet the downside
of the Vitelmat™ with half the required amount of resin and evenly bed this into the fibreglass. Complete the wet
out using the remaining resin.
You can form Vitelmat™ to fit almost any shape after some
30 seconds or so.
Once another layer of fibreglass has been applied to the
Vitelmat™, you can continue the process. |

Uses and applications :
Over the years, the use of FRPs in the
construction industry has become prevalent,
with the high strength-to-weight ratio being
of significant benefit.
It stands to reason that the flexural strength of any laminate will
depend greatly on the total density, which is built up by applying
a number of flat layers to a core. Typically these external layers
(skins) consist of fibreglass mats, woven roving and a protective
finish (gel-coat). The main purpose of the core is to provide
flexural strength through a thicker laminate, but with a very low
proportional weight.
Fibreglass and resin can be used to build up the core, but these
inevitably result in a heavy structure. Therefore, it is
advantageous to use a low-density core material, which can
provide all the benefits for very little additional weight.
Although other materials such as plywood or polyurethane can
be used as a core, poor adhesion between the core and resin
is likely to occur, resulting in poor durability. However, no such
problems exist with Vitelmat™.
Laminating resin is easily absorbed through the voids and is
then evenly displaced by the expandable micro-spheres.
The resultant core can be up to 30% lower in weight than the
equivalent thickness of an all-glass lay up.
This makes Vitelmat™ the ideal solution for any number of FRP
applications that require rigidity with minimal weight, such as:
