Brandenburger - Glass Fibre

GFRP is a `programmable` material. The glass fibres may be aligned to precisely match the loads in the sewer. Pipe liners made of GFRP are capable of bearing extreme loads at very low wall thicknesses and weights. GFRP pipe liner is thus suitable for the rehabilitation of all commonly used sewer cross-sections - round, oval and special profiles - with small and large diameters.

During the manufacturing of the Brandenburger GFRP pipe liner, glass fibre webs are immersed in special vinyl or polyester resin to strengthen the mechanical properties of the plastic. It is critical for the durability of the finished product that the composition of the resins matches perfectly with the type of glass in order to withstand the chemical and mechanical loads. This is why only high-grade resins (polyester resin pursuant to DIN 18820 group 3 type 1140, or EN 13121 group 4, or vinylester resins pursuant to DIN 18820 group 5 type 1310, or EN 13121 group 7A) and corrosion-resistant E-CR glass fibre are used for Brandenburger GFRP pipe liners.
