ATL Composites specialise in the development, and manufacture, of lightweight composite panels suitable for use in the marine, road transportation, rail transportation, industrial and architectural industries.
Panels are available with a variety of core types including PVC and SAN foam cores, aramid honeycomb, and BALTEK® rigid end grain balsa cores for structural applications such as the construction of yacht hulls and bulkheads, truck beds, bus and train floors, industrial holding tanks and long span roofing.
Super lightweight, non-structural panels for yacht interiors are available with lower density foam cores and phenolic impregnated paper honeycomb.
Panels can be finished with epoxy laminates reinforced with E-fibreglass or carbon fibre, and can be engineered and manufactured to meet the rules of all major marine regulatory authorities. Timber, metal or decorative timber veneers, and specific fire-rated finishes, are also available.

FireStop® panels were developed for semi-structural applications where fire protection is a primary concern. Phenolic laminates are constructed from random CSM (chopped strand mat) for near isotropic mechanical properties, and provide an optimized, resin-rich, fire barrier with low smoke characteristics and extended time to ignition.
FireStopR has undergone and passed the AS1530.0 Fire Tests for Ignitability Index, Spread of Flame Index, Heat Evolved Index and Smoke Developed Index.
Typical applications include marine bulkheads, doors and hatches with fire resisting requirements, rail floors, wall, doors, roof and interior partitions, automotive floors and partitions, and architectural fire resistant fascia panels and interior partitions.

|
|
ATL developed Featherlight® panels specifically to provide the user with a lightweight option for non-structural interior applications. At under 1kg/m2, Featherlight helps to maintain control over finished weight while providing superior levels of stiffness, and thermal & acoustical insulating properties.
Featherlight panels are perfect for yacht cabinetry, non-structural bulkheads, and general fitout, and curved surfaces are achieved without effort by simply kerf-cutting the inside skin.
Non marine applications include, rail walls, roof panels, interior partitions and modules, and architectural room partitions and other interior structures requiring thermal &acoustical insulating properties, curtain walls in new construction, and fascia panels for re-modeling older exteriors.

>> DuFLEX

DuFLEX™ panels were specifically designed to reduce construction time and to optimize 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.
Standard DuFLEX panels are cored with rigid end-grain balsa or structural foam cores*, and laminated with a high performance epoxy resin reinforced with multiaxial E-fibreglass or carbon fibre skins. 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 panels are finished with peel ply to protect the laminates from contamination and to reduce the amount of preparation required prior to secondary bonding or laminating.
Typical applications
Marine
Hull shells, decks, superstructures, bulkheads, frames, stringers, partitioning and furniture for one-off construction, prototypes and running plugs. DuFLEX can also be used to extend or modify hulls or superstructures on existing boats.
Road
Truck beds, bodies, side walls and bus floors Industrial Holding tanks, staging, walkways, formwork, and audio visual equipment containers
Rail
Flooring, roof/ceiling construction, cabinetry &interiors, and doors
Architectural
Long span roofing and lightweight wall panels
Expandability
To offset their individual size, DuFLEX panels can be supplied with both long edges pre-machined to facilitate joining. This Z-Joint is structurally effective and achieves a smooth and fair surface profile.
To streamline the joining process, ATL Composites have developed the proprietary DuFLEX Z-Press. This press applies heat and pressure to cure the epoxy adhesive used to bond the joint, and panel length can be increased at a rate of 1.2 lineal metres per join.
Kits
ATL Composites used computer aided design and manufacture (CAD/CAM) processes, combined with computer numeric control (CNC) equipment to produce pre-fabricated DuFLEX kits.
Electronic files are supplied by designers and all parts required for the project are nested together within the panels to reduce wastage. Once the panels are manufactured, the CAD information is used by a CNC router to machine the programmed shapes into the panels.
Each pre-cut part is left attached to the panel by small tabs to ensure the kit arrives with all components securely in place. The tabs are easily cut away, when the panels are joined, and construction commences.
The DuFLEX kit-building system minimises structural weight, material waste, labour and tooling costs, tighten design allowables, improves product quality, simplifies quotations, and reduces VOC emissions.
Strips
Compound surfaces such as sailboat hulls and the flared topsides in sport fishing boats can be made by bending and edge-gluing DuFLEX Strips around temporary frames, as with traditional strip planking.
DuFLEX Strips are pre-laminated with unidirectional reinforcements which allow the strips to conform readily to highly concave or convex shapes, and can provide up to 50% of the total laminate. The stiffness imparted by the reinforcement, allows the strips to bend fairly over half the number of frames normally required by other strip systems, and increases the stability when turning the hull.
DuFLEX Strips also allow builders to recoup a good deal of new-modelling costs when building running plugs and proto-types for production models.

| >> DuraKore |
|
|
Developed by ATL Composites, DuraKore® Strip Planks combine the best elements of traditional wooden boat building techniques with advanced, lightweight, composite materials. Engineered as an advance in marine strip planking construction, DuraKore® builds a stiffer structure with less weight than conventional timber materials. It is easier to form into shape, better to handle, and more durable.
DuraKore® brings sophisticated composite boat construction within the reach of anyone possessing reasonable mechanical/woodworking skills. Construction proceeds in small, logical steps, and allows the home builder to achieve a high quality finish.
The professional builder will find that DuraKore® allows construction of a very competitive boat in terms of strength-to-weight, stiffness-to-weight, and durability, at less cost than other forms of one-off construction. DuraKore® is also excellent for building running plugs and prototypes, allowing production builders the opportunity to recoup a good deal of new-model tooling costs.
