Coremat is a polyester nonwoven that contains microspheres and is used as at thin core (bulker mat) or print blocker (liner) in fibre reinforced laminated, manufactured in Hand Lay-Up or Spray-Up processes. Coremat should always be fully impregnated with resin.The microspheares in Coremat prevent excessive resin up-take. The most important resons to use Coremat are:

• Weight saving
• Resin and glass saving
• Increase stiffness
• Fast thickness build-up
• Excellent surfase finish

Coremat Xi

Coremat Xi is the world standard for bulk mats. The Coremat resin consumption is about 600 grams per mm thickness. It contains a resin indicator which changes colour to show that resin has been applied to the Coremat.

Coremat Xi is very soft and pliable when it is wet and therefore very suitable for complex shapes.

Key properties Xi:

Coremat XM has a low resin take up: 500 gram of reain per mm thicknerss. It is therefore suitable for weight critical application . The hexagonal cell pattern resuls in a very consistent thickness in the product. Coremat XM has very good wet tensile strength properties; it is therefor often used in application where mats are pre-wetted outside the mould. Generally customers choose XM, because of its smoothness. ease of working, and resin savings. Key properties XM:

• Honeycomb structure for
• excellent drapeability
• Extre resin saving
• High wet strength

Lantor Soric® Flexible Core

Core material and infusion medium in one

Soric is a polyester nonwoven material with a compression resistant hexagonal (XF, SF, LRC) or random dot-printed (TF) cell structure. These pressure-resistant cells, which are separated by channels, contain synthetic micro-spheres.
The cells do not absorb resin and therefore limit the total resin up-take. Since these cells are pressure resistant, they create thickness in the laminate even when pressure is applied by vacuum bag. The channels facilitate resin flow and form a pattern of cured resin with good mechanical properties and excellent bonding to the outer skins.

Because of these unique properties and characteristics, Soric can be used as:

• Thin core (bulker), adding stiffness, while reducing weight
• Inter-laminar resin flow medium, eliminating the need for other (disposable) flow media
• Print blocker (liner), that meets the most demanding cosmetic and finish requirements.

Soric SF is the general purpose grade, balancing resin flow and surface quality. Soric SF is therefore especially suitable for thinner laminates.

Soric XF maximises weight reduction in structural core applications. Soric XF offers the fastest resin flow for the lowest resin consumption, and is therefore ideal for thicker laminates.
Soric TF

spec_Soric XF

Soric TF is the ideal product for the most demanding cosmetic and surface finish requirements. Soric TF can be used as a core, but is most often used as a print blocker in infused laminates.

Soric LRC is the latest grade in the Soric product line. Soric LRC has a resin uptake of about 350 g/m2/mm.
Soric LRC is now commercially available in thicknesses of 1.5 mm, 2 mm and 3 mm.

Naval

Lantor core materials can be applied to all composite parts, including Cruise/ferry ships
- interior panelling, floor, ceiling, seating, doors, decks, hulls, hatch covers, steering consoles, shower cabinets and chairs.
Lantor Coremat® is used as a core material in decks and hulls or as a print barrier in hull sides.
Lantor Soric® is used in closed mould processes as a flexible core, interlaminar infusion medium and print barrier.

Lantor Finishmat® D7760 is used in closed mould processes to prevent print through effect and provide the laminate with a class-A finish. For additional information on print through blocking and osmosis prevention with Lantor Soric TF and Lantor Finishmat D7760

Lantor Soric in Superbus project
Lantor Soric will be used as core material in the dutch Superbus project. Lantor Soric suits perfect in this light weight full composite application.A new type of public transport is being developed in the Netherlands by the
TU Delft which relies on lightweight composite construction and will be
demonstrated at the Beijing Olympics in August 2008. In the search for a non-polluting, fast, economic and appealing new means of public transportation, a project has started in the Netherlands for the realisation of an electric vehicle called Superbus.

Lantor Coremat in bus parts
Fiberbus Brazil builds various bus parts, using spray-up, hand lay up and RTM Light production processes. In their open mould production they use Lantor Coremat to create extra stiffness in i.e. stairs, bus front-covers or parts where they need extra thickness for screwing in handle bars and grips

Case Study in Aerospace

Lantor Coremat in UAV

The Aerostar Tactical Unmanned Air Vehicle System (TUAV) provides reliable, high quality real time intelligence gathering capability. The system was developed by the Company’s leading engineers in cooperation with the Israeli Intelligence Corps. The system has accumulated thousands of operational hours, giving the system its maturity, reliability and credibility. Among the system’s customers are the IDF, U.S. Navy, Angola and other customers around the globe.
The Aerostar has a wing span of 7.5 m and uses Coremat XM to create the right stiffness needed for the wings, without adding o lot of extra weight. The wings are made of a carbon-epoxy system.Download full details
