Unidirectional Carbon Laminate (UCL™) is a modern and highly efficient material used in the construction industry and for structural retrofitting. It belongs to the Fiber-Reinforced Polymers (FRP) category and comprises carbon fibers (CFRP) embedded in epoxy resin. The unique properties of UCLTM have made it widely utilized in reconstructing and retrofitting structures, particularly old, damaged, or overloaded structures.
UCL™, often called carbon fiber sheets or carbon fiber plates, consists of FRP sheet laminates primarily composed of CFRP. These laminates are excellent support components, offering dimensional stability, low creep, and high flexural strength. They find a wide range of applications in various fields. Furthermore, their exceptional insulating properties and resistance to high heat make them highly valuable for primary and secondary electrical insulation and thermal barriers.

PRODUCT DESCRIPTION

What is Carbon Fiber Laminate?

Afzir Carbon Fiber Laminate Sheet comprises carbon fibers arranged in an epoxy resin matrix. The materials are carefully molded and hardened to create plates for reinforcement and retrofitting in engineering and construction projects.

Pre-processed FRP carbon laminate is manufactured in factories to ensure higher quality and uniformity than other products. This is achieved through a higher fiber-to-resin ratio, resulting in increased strength and hardness during wet layering. The prefabricated carbon laminate is typically produced with a width of 50-100 mm and a thickness of approximately 1.3-1.4 mm. During installation, these laminated tapes are bonded to the outer surface of structures using an epoxy resin adhesive.
Carbon laminate sheets are made from carbon fibers that possess four times the tensile strength of steel. These products have a tensile strength exceeding 2400 MPa and are available in rolls with a length of 100 meters. Carbon laminate sheets are suitable for unique applications previously challenging conventional wet layering systems. They find usage in cases where high strength and low weight are critical, ranging from drones to car and motorcycle parts.

Critical Properties of Carbon Fiber

We focus on producing high-quality products that deliver exceptional performance in demanding conditions. Carbon fiber sheets, in general, exhibit high resistance to continuous loads and perform well against tensile, compressive, and flexural forces. They also demonstrate excellent performance in plate shear and interlaminar shear. Carbon fiber sheets offer superior tensile strength, flexural modulus, heat distortion temperature, and linear expansion compared to other epoxy laminates. The woven layers of pure carbon fiber bonded with hard plastics like epoxy resin make carbon laminates exceptionally strong. Additionally, unidirectional carbon fiber sheets’ maximum tensile and flexural strength align along a specific axis.

Pultrusion Carbon Fiber Laminate (CFRP) for Structural Reinforcement

Carbon laminate is a rigid polymer reinforced with polyurethane carbon fiber to strengthen concrete, masonry, steel, and wood structures. The CFRP laminate acts as an external support element, bonded to the substrate using FRP tape epoxy adhesive.

Why Consider Carbon Fiber Sheets in the Automotive Industry?

As we know, carbon laminate exhibits high strength and lightweight characteristics, making it highly beneficial in reducing the weight of vehicles, enhancing body strength, and lowering fuel consumption. Therefore, using carbon fiber sheets in automobiles can lead to significant advancements and energy savings, which have far-reaching societal implications.
The adoption of FRP carbon laminate in the automotive industry is expected to experience substantial growth.

Four Key Advantages of Carbon Fiber Sheets in Automotive Applications:

Weight Reduction

Carbon Fiber Sheet Pricing

The global market value of carbon fiber composites is projected to rise from $70.4 billion in 2020 to $112.8 billion by 2025. Composites exhibit exceptional properties such as hardness, strength, adhesion, thermal and electrical conductivity, fatigue, and corrosion resistance. These outstanding properties have led to the preference for composites over conventional materials like steel and aluminum in high-performance industrial applications.
In terms of carbon fiber sheet prices, carbon fiber composites are experiencing the fastest growth among fiber composites. Carbon fiber composites are expected to dominate in value between 2020 and 2025. Carbon fiber is twice as strong and 30% lighter than fiberglass and traditional fibers. Its utilization is anticipated to persist in various industries for a significant period.

Frequently asked questions

FRP sheet or laminate is made of a combination of several layers of unidirectional or bidirectional fiber fabric made of carbon fibers, glass, etc., along with epoxy resin, polyester, vinyl ester, etc. FRP sheets are marketed in different dimensions and thicknesses depending on the intended application. FRP sheets or laminates, due to their light weight, have several times more mechanical properties than steel, aluminum and other materials. For this purpose, FRP laminates are widely used in the implementation of reinforcement designs.

To install laminates made of carbon fiber, the surface must first be cleaned of any contamination. Then the FRP laminates should be cut according to the dimensions stated in the reinforcement design plan, using a saw, and finally, using epoxy resin, to the desired surface.

Frp sheet or laminate is widely used in various industries such as construction, aerospace, medical equipment, sports products, etc. Frp laminate is commonly used in the construction industry to improve and enhance the mechanical properties of structural elements.

Features of carbon sheet include high flexural and shear strength, low weight, impermeability, high stability and durability, compatibility with most materials, long service life, ease of installation, high resistance to corrosion, high resistance to heat pointed out.

Carbon sheets and laminates should be stored in a dry place at 4 to 40 °C.

Approved personal protective equipment should always be available. The mask is recommended to prevent airborne particles (particles from cutting fibers) from entering the lungs and gloves to prevent skin irritation when handling fabric and resin. Eye shield is recommended to prevent eye irritation. The ventilation system must be completely standard and in the absence of proper ventilation, the use of a respirator is mandatory.

Dried materials can be cleaned with approved solvents. But the dried material can only be disposed of mechanically, the material must be disposed of in accordance with waste disposal regulations.

For best results from installing carbon sheets and laminates using laminate resin, it should be done at a temperature of 5 to 30 degrees Celsius.

Frp sheets and laminates are usually sold in the market on a unit length basis. The price of Frp laminates is priced based on the dimensions, thickness and type of resin used in the sheet production process. It is not possible to offer a single price due to fluctuations in the market.
