Owing to its exceptional properties Curv® offers a wide range
of possible applications including flat sheets, moulded parts and the outer skin
in sandwich constructions.

Because Curv® is 100% thermoplastic it may be readily
parts by thermoforming.
Modest heating requirements, low hydraulic pressures and lower cost tooling all
contribute towards lowering the cost of making high performance composite parts.
For prototype parts resin or wooden tools may be used whilst for production
parts aluminium tools are recommended.
Best results are achieved using matched tooling at pressures from 5 bars upwards
depending on the complexity of the part.
Curv® sheets can be heated to the required processing temperature (c. 150 -
160ºC) by infra red, contact plate heater or air convection without shrinking or
otherwise deforming. Heated sheets are easy to handle either manually or by
robot and may be either clamped or allowed restricted flow into the mould cavity
depending on the complexity of the part being produced.
Stamp forming gives the highest definition and because Curv®s self reinforcing
fibres are partially extensible, unlike glass or other common reinforcements,
even fibre distribution is achieved with minimal thinning in high draw areas.
Cycle times of less than 60 seconds are achievable.

Post moulding operations are made easy by Curv®s lack of
glass or mineral filler resulting in lower cutting tool costs and improved tool
life. Curv® may be punched, machined or alternatively may be cut by water jet.
Joining and bonding
Curv® may be joined and fittings attached by ultra-sonic
welding and for ease of dismantling mechanical fasteners
may be used without risk of ‘pull through’.
A number of adhesives are available for bonding Curv®. In addition, Curv® can be
supplied with specially modified surfaces to allow bonding to a wide range of
other materials. Contact us for more information.
Curv® may be used in conjunction with
produce sandwich structures offering
• high stiffness without ribbing
• ultra light weight
• all polypropylene
• controlled deformation on impact

Even in flow moulding processes (of GMT or LFTs) or in the
injection moulding process (with PP or LFTs) Curv® can be integrated and
local reinforcements. Thus the excellent impact performance,
abrasion resistance and energy absorbing behavior Curv® can be used to improve
the performance in defined areas of your parts.
WHY local reinforcement ?
• to improve impact performance
• to improve crash behavior / energy absorption
• to improve abrasion resistance
• to reduce wall thickness
HOW to reinforce parts ?
• by overmolding with GMT or LFT
• by back injection with PP or LFT
• Curv® has to be pre-heated (110-150°C)
• reinforcement strip/sheet has to be fixed in the tool
• overmolding/overinjection by PP, GMT or LFT at 210 -250°C
Due to the flexibility of our state of the art production
equipment we are able to produce a range of customized products for specific
applications. Examples include Curv® in combination with
