 omposite
materials can be used in a number of applications
within the transportation market -- from exterior door panels,
radiators and ignition components on passenger vehicles, to the side
panels on light- and heavy-duty trucks. The benefits of using composites
include greater fuel efficiency, corrosion resistance, low weight
and high strength. Composites also provide a low-cost way to help
keep designs looking fresh.

On passenger vehicles, light trucks and buses, composite parts are
usually classified in four categories:
|
|
 |
|
|
|
Body panels and accessories
where they meet high requirements: freedom of design, lightness, class
A surface finish, impact resistance, freedom from rust.
Examples are very numerous: bodyworks, spoilers, door panels, hoods,
hatchbacks, roof panels, bonnets, wing mirrors, rear light units,
brake linings, ignition components.

Internal parts and trim where they
are the solution to lightness, freedom of shape, freedom of design,
matching internal decor
and providing thermal and acoustical insulation.

They are used to mold interior components for buses, seat squabs
and bases, car door liners, back panel of seats, parcel shelves…

Structural and semi-structural parts made
of composite show
flexural strength and rigidity, impact resistance, lightness
and allow functional integration.
Parts often have a high-glass content: front-end panels, floor, engine
block, bumper beams, leaf springs, spare wheels and covers, fuel tank
supports. These also include heat-resistant under-bonnet parts: inlet
manifold, cooling modules, oil pan.

Transportation also includes railway
and bus equipment (body
work, cabs and internal components) and also large panels for trucks,
trailers and containers.
