WHY USE COMPOSITES
SKI MANUFACTURE?
FOR
H
excel Corporation is the global leader in the advanced structural materials
industry. The company manufactures lightweight, high performance
carbon fibres, industrial fabrics, composite materials, engineered parts and
structures, and sells them to customers in the commercial aerospace, space and
defence, recreation and general industrial markets.
PREPREGS AND LAMINATES
Hexcel Composites supports customers worldwide with state of the art production
facilities and equipment designed for the cost-effective manufacture of:
● Provide a better working environment than wet lay-up and
easier handling.
■ Structural Film Adhesives
■ Honeycomb Sandwich Panels
■ RTM Materials
● Give weight reductions over wet lay-up, as they have a lower
resin content.
To find out how Hexcel Composites can solve your materials problems please
contact us.
● Give a more closely defined product, with an exact resin
content, making it easy to mass produce skis to an exact
specification (thickness and weight).
POLYURETHANE (PUR) AND HONEYCOMBS
● Provide significant weight-savings over wood core, with no
loss of stiffness.
● PUR reduces production times (less than 10 minutes from
mould preparation to demoulding), and reduces the number
of components.
● PUR can provide excellent adhesive properties, and an ideal
balance of flexibility and stiffness when combined with
laminates.
● The use of RIM material makes production extremely quick
and provides excellent adhesive properties.
● Rigid foams are less expensive than wood, with no moisture
pick-up.
● Rigid foams can incorporate integral design features such as
distancing devices, which have to be inserted manually with
wood.
● With PUR foams there is very little material wastage, making
them more economical than wood or honeycombs.
● Honeycombs combine very low weight with excellent
stiffness.
■ Special Process Honeycombs
■ Honeycomb Cores
■ Carbon, Glass, Aramid and Hybrid Prepregs
