About this product

CFM for Press moulding

3B Continuous Filament Mat (CFM) is a non-woven mat made out of E-CR glass filaments, consisting of continuous fibres randomly oriented in multiple layers. The glass fibre is bonded with a silane coupling agent and the layers are held together with a suitable binder. The M 8630 family products contain an insoluble binder compatible with a large range of thermoset matrices like both unfilled or filled unsaturated polyester, vinyl ester, epoxy and polyurethane resin systems. The M 8630 emulsion mat is ideally suited for matched metal die moulding, RTM and S-RIM processes for moulding flat, large and heavy panels or non complex parts. The excellent mechanical properties provided by 3B CFM combined with the good electrical properties of the resins make the moulded parts attractive for applications like electrical apparatus (high voltage), transportation industries and infrastructures equipments.

FEATURES - Integrity and rigidity of the mat - Porosity

BENEFITS - Designed for large panel production - Can be unrolled, cut and conveyed to the mould without loosing mat integrity even with large parts - Easy to tailor to shape design without causing wrinkles or leaving resin-rich radii, which may cause craking - Resist to relocation in the mould under pressure and resin flow (wash resistance) - Little resistance to resin flow for an easy and fast wet-through, even with filled resin

PACKAGING The 3B Continuous Filament Mat is wound on a hard carton tube with an inside hole of 102 mm and an external diameter of 110 mm. A PE stretch film is wrapped around the roll to protect the material during handling and to help the slicing. All 3B CFM rolls have 2 sides trimmed.The outside diameter of the roll is a standard of 55 cm. · For mat widths up to 210 mm:6 vertical rolls per pallet · For mat widths above 210 mm:6 horizontal rolls per pallet For more details on the packaging, please refer to the CFM Packaging Datasheet.

STORAGE Storage in a cool and dry warehouse into the original packaging is formally recommended. More precisely ideal storage conditions are a temperature between 15°C and 35°C and a relative humidity comprised between 35% and 75%. If these conditions are maintained, the glass fibre product should not undergo significant changes when stored for extended periods of time. It is also strongly recommended to condition it in the workshop for at least 24 hours before use to prevent condensation.For an optimal processing we recommend to use the product in ambient conditions (20°C-23°C and a relative humidity of 60%-65%).

Continuous Filament Mat 3B’s Continuous Filament Mat (CFM) is a non-woven mat made from 3B E-CR glass filaments, consisting of continuous fibres randomly orientated in multiple layers. The glass fibre is bonded with a silane coupling agent and the layers held together with a suitable binder. 3B offers two groups of CFM: powder mats emulsion mats Both provide end-users with different controls over rigidity, conformability, handling, wet-out and a range of tensile strengths. CFM is particularly suitable for compression moulded electrical and non-electrical laminates as well as for pultrusion and infusion or injection processes (e.g. RTM, S-RIM or Matched Die Moulding). CFM products contain an insoluble binder for unsaturated polyester, epoxy and polyurethane compatibility in unfilled or filled resin systems. In certain applications, 3B CFM also shows good compatibility with polyurethane foams.
