Product Introduction
ZRETE bidirectional carbon fiber fabric is a high-performance CFRP material designed for structural strengthening of concrete members. With fibers oriented in both warp and weft directions, the fabric provides balanced reinforcement against tensile and shear stresses. When combined with structural epoxy adhesive, the CFRP system significantly improves flexural strength, crack resistance, and seismic performance of reinforced concrete elements. It is lightweight, easy to apply on site, and delivers excellent durability in harsh environments such as marine structures, bridges, and tunnels.
Balanced bidirectional reinforcement, superior to unidirectional systems in multi-directional stress conditions.
Excellent adhesion with ZRETE structural epoxy adhesive for reliable composite performance.
Lightweight, easy to transport and install without heavy equipment.
Proven field performance in bridges, tunnels, marine projects, and seismic retrofits.
Supported by technical expertise, CNAS-certified testing, and global project references.

Q1: What is the advantage of bidirectional over unidirectional fabric?
A1: Bidirectional fabric reinforces in both directions, improving shear and multidirectional load resistance, while unidirectional is optimized for tensile strength in one direction.
Q2: Can this fabric be used in marine or humid environments?
A2: Yes. Combined with epoxy adhesive, the CFRP system offers excellent corrosion resistance, making it suitable for coastal, marine, and underground structures.
Q3: How is the installation process performed?
A3: Surfaces are cleaned and primed, epoxy adhesive is applied, then the carbon fiber fabric is laid, impregnated, and cured. The system is lightweight and easy to handle on site.
Q4: What certifications support this product?
A4: ZRETE CFRP systems are tested in accordance with international standards, with mechanical properties verified by CNAS-certified laboratories.
