Carbon Repair & Strengthening

Retrofit structural solutions based on CFRP

ASTEC Carbon Solutions is a range of 3 products based on the same innovative composite material: Carbon Fiber Reinforced Polymer. ASTEC CFRP offer amazing properties: 4 times the tensile performance of steel for only 1/4 of the weight.

In the past 20 years have emerged new structural applications for Carbon fiber based elements:

External Bonding Reinforcement (EBR), where a carbon laminate is applied on the surface to increase the flexural and shear strength of the member.

NSM (Near Surface Mount) applications, where a carbon rod or tape is inserted in a cut groove with cement grouting or epoxy adhesive. NSM offers a gain of 4.8x the flexural strength compared to EBR technique.

External post-tensioning applications, where a carbon rod is installed below a concrete member thanks to state-of-the-art splicing system.

Product features

ASTEC CFRP Repair & Strengthening range is available in 3 forms: laminate, tape and rod.
Laminate: 50 or 100mm width with thickness of 1.4mm for an ultimate tensile load up to 336 kN.
Tape: 16mm width and available in two thicknesses foran ultimate tensile load of 140 kN.
Rod: 3 diameters up to 218 kN ultimate tensile load capacity. Our rod solution features innovative connectors to allow the installation as PT applications.
Designed as per ACI440.2R-08 , ACI440.74, ACI-440.7R and FIB Task group 9.3. Tested as per ACI 440-3R-12.

Aerospacial

Grade material

High weight to strength

4x the performance of steel for only 25% of the weight.

Minimum visual impact

Extremely thin solutions that can be hidden into cut grooves.

Benefits

Fast to install.
Cost effective.
Durable: no maintenance, no post inspection.
Limited visual impact, thanks to a compact size and applications where the CFRP is hidden into a cut groove.
Can be installed in all weather conditions.
Also fits wooden structures.
