LANTOR COMPOSITES:

The Lantor Composites® division offers a comprehensive range of innovative nonwoven solutions for the Composites (Fiber Reinforced Plastics) industry. Lantor Composites has been building a solid reputation ever since it introduced nonwoven core materials to the Composites industry as a time and cost-saving solution.

In close cooperation with the world’s leading end-users and institutes, successive generations of Lantor Mat products have been developed for specific applications in the marine, transportation, construction, leisure, sanitary and aerospace industries.

Products: COREMAT & SORIC: Nonwooven polyesters”.

          1) The Nonwoven core and liner for hand lay-up and spray-up processes
Coremat is a polyester nonwoven that contains microspheres and is used as a thin core (bulker mat) or print blocker (liner) in fibre reinforced laminates, manufactured in Hand Lay-Up or Spray-Up processes. Coremat should always be fully impregnated with resin the microspheres in Coremat prevent excessive resin up-take. The most important reasons to use Coremat are:

  •           Weight saving

  •           Resin and glass saving

  •           Stiffness increase

  •           Fast thickness build-up

  •           Excellent surface finish 

Coremat® Xi

Lantor 1 Coremat Xi is the world’s standard for bulker 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

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

Coremat® XM

Lantor 2 Coremat XM has a low resin take up: 500 gram of resin per mm thickness. It is therefore suitable for weight critical applications. The hexagonal cell pattern results in a very consistent thickness in the product. Coremat XM has a very high wet tensile strength; it is therefore often used in applications where mats are pre-wetted outside the mould.

Key properties Xi:                                                                  Key properties XM:

Resin indicator                                                                                           Honeycomb structure for excellent drapeablity

Excellent impregnation                                                                              Extra resin saving

High drapeability in resin                                                                          High wet strength

Coremat® XM 10

Lantor 3 Use Coremat XM 10 to replace plywood of rigid materials like foam or plastic cores.
Coremat has good screw retention and does not have rot issues, contrary to wood.

 

 

Coremat saves weight
Coremat as a core material is used in the center of a laminate. Coremat can replace much heavier solid glass layers. Impregnated Coremat has a density of 610 kg/m3 (38 lb/ft2), while Impregnated Chopped Strand Mat has a density of 1,500 kg/m3 (94 lb/ft3). This is a weight saving of 60%.

Coremat saves resin and glass
Coremat contains less resin than CSM: 1 mm (0.039 inch) of Coremat contains 0.6 kg/m2 (2.0 oz/ft2) while 1 mm (0.039 inch) of CSM contains 1 kg/m2 (3.31 oz/ft2). Although Coremat usually replaces glass layers, it should always be used between glass layers. 

Coremat saves labor
One layer of Coremat builds up thickness rapidly. Coremat is 1 to 10 mm (0.04-0.39 inch) thick. While multiple layers of glass fiber are required to achieve these greater thicknesses, One layer of Coremat is sufficient. 

Coremat is an excellent print blocker
Coremat can be used to block “print-through” of glass reinforcements and cores, especially when dark gelcoat surface finishes are used. Coremat is most often applied against the “skin coat” to create a superior surface finish on hull sides.

          2)    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

 Lantor 4 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 XF

Lantor 5 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

Lantor 6 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
(Low Resin Consumption)

Lantor 7 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.

Soric XXF

Lantor 8 Soric XXF is a grade specially developed for blade manufacturing. To support resin transportation in critical area’s of the blade. Soric XXF is available in thicknesses of 1.5 and 2 mm.
