DuFLEX
TM
panels are specifically designed to reduce
construction time and to optimise structural weight in
high performance composite structures. Time-
consuming laminating, coring and vacuum bagging
steps normally required to fabricate high performance
composites are avoided, and material waste, labour
and tooling costs are greatly reduced.
DuFLEX
TM
panels are 2400mm x 1200mm with
multiaxial E-fibreglass or carbon fibre skins, laminated
with a high performance epoxy resin. Fibre orientation
and ply schedules are based on design or engineering
specifications to best meet weight targets, stress and
impact loads, and other design parameters.
The laminates are finished with peel ply to protect the
laminate from contamination and to reduce
preparation of the surface prior to secondary
bonding or laminating.
End grain balsa has an extremely high strength-to-
weight ratio, excellent mechanical properties, good
thermal and sound insulation properties, high impact
and fatigue resistance and good moisture resistance.
Typical applications include hull shells, decks, super-
structures, bulkheads, frames and stringers in one-off
construction, prototypes and running plugs. Non
marine applications include, rail floors, wall, doors,
roof and interior partitions, automotive floors and
truck bodies, and architectural long span roofing and
partitions.

All timber used in the manufacture of DuFLEX Composite Panels is plantation grown. ATL Composites reserves the right to alter
specifications without prior notice. Weight may vary due to variations in core density.
CUTTING

Diamond-coated fiberglass tooling is recommended
for best tool life. The best edge finish is achieved with
circular saws running aluminium cutting blades,
however blade life is greatly reduced.
KITS
ATL Composites offers in-house CAD and CNC
cutting services, and can produce pre-fabricated
DuFLEX kits from electronic design files.
JOINING
& BONDING
To offset the individual size of the panel, DuFLEX can
be supplied with both long edges pre-machined to
facilitate joining. The Z-Joint is structurally effective
and achieves a smooth and fair surface profile. A
high density epoxy adhesive is specified for joining
DuFLEX Z-joints. Contact ATL Composites for
suitable adhesives.
Manual joining of the panels is also possible,
Contact ATL Composites for specific details.
