Balanced highstrength bidirectional carbon fibre fabric

BI-AXMapeWrap C BI-AX

WHERE TO USE by high modulus of elasticity (comparable to steel) andvery high tensile strength that can be placed using twodifferent methods:– wet system;– dry systemby using the following range of epoxy resins:– This system is suitable to repair and improve the flexuraland shear strength of reinforced concrete elements damaged by physical-mechanical actions. Some application examples • Repair, maintenance and static upgrade ofdeteriorated structures, where it is absolutelynecessary to reinforce the flexural and shear strengthof the cross section.• Confinement of axially loaded or damaged concreteelements (columns, bridge piers, chimneys) in order toimprove ductility and load bearing capacity where atthe same time it is necessary to compensate the reduction of the area that needs reinforcement.• Seismic strengthening and restoration of vaultedstructures without the increase of seismic mass andwithout the danger of liquid percolation towards the internal surface of an archway.• Repair of bidimensional structures such as slabs,plates, small vaults and tanks.• Repair of structures damaged by fire. • Reinforcement of load bearing elements in buildingsthat have been restructured for architectural reasonsor change of use. Mapewrap Primer 1 , strengthening for the treatmentof the substrate.– Mapewrap 11 and 12 , smoothing compounds tosmooth any rough areas or to seal porous surfaces( Mapewrap 12 has a longer workability).– Mapewrap 21 , impregnating agent for fabrics by “wetsystem”.– Mapewrap 31 , impregnating agent for fabrics by “drysystem”.Using the “wet system”, the Mapewrap fabric ismanually dipped into Mapewrap 21 immediately beforeplacing on the surface. When using the “dry system”,the dry fabric is placed directly on a layer of Mapewrap 31 which has been applied to the concreteelement that needs reinforcement.In order to satisfy the most diverse needs, Mapewrap C BI-AX is manufactured in two differentweights, each with different widths (20 and 40 cm):- TECHNICAL CHARACTERISTICS Mapewrap C BI-AX is a bidirectional continuouscarbon fibre fabric with balanced weight characterized Mapewrap C BI-AX 230 (238 g/m
2 );- Mapewrap C BI-AX 360 (360 g/m
2 ).
