Carbon fiber fabric
Carbon fiber fabric
Carbon fiber is first of all a substance, which is made of carbon at a temperature above 1000°C, which is the same material as diamond.
Carbon fiber cloth
Carbon fiber cloth is also called carbon fiber cloth, carbon fiber cloth, carbon fiber woven cloth, carbon fiber prepreg cloth, carbon fiber reinforced cloth, carbon cloth, carbon fiber fabric, carbon fiber tape, carbon fiber sheet (prepreg cloth), etc. Carbon fiber reinforced cloth is a unidirectional carbon fiber reinforced product, usually woven with 12K carbon fiber filaments.
Available in two thicknesses: 0.111mm (200g) and 0.167mm (300g). Various widths: 100mm, 150mm, 200mm, 300mm, 500mm and other special widths required for projects. With the continuous development of the carbon fiber cloth industry, more and more industries and companies are using carbon fiber cloth, and some companies have entered the carbon fiber cloth industry and developed.
Carbon fiber cloth is used for tensile, shear and seismic reinforcement of structural components. This material is used together with matching impregnating glue to form a carbon fiber composite material, which can form a complete carbon fiber cloth sheet reinforcement system with excellent performance and is suitable for handling building loads. Reinforcement projects include additions, changes in project use functions, material aging, concrete strength levels lower than design values, structural crack treatment, repair of components serving in harsh environments, and protection.
Carbon fiber is a new type of non-metallic material. It and its composite materials have high specific strength, high specific modulus, fatigue resistance, creep resistance, high temperature resistance, corrosion resistance, wear resistance, dimensional stability, electrical conductivity, thermal conductivity, and thermal expansion coefficient. Small, self-lubricating, energy-absorbing and shock-resistant and a series of excellent properties.
Another important feature of carbon fiber is its small specific gravity. The specific gravity is generally around 1.6, which is one-half of aluminum and one-fifth of steel. Although carbon fiber is light in weight, it has high strength and a high “specific strength” (specific strength = strength limit of the material/unit weight of the material). Its specific strength is 5 times that of steel, and its rigidity is very good.
Product Features
It has high strength, low density and thin thickness, and basically does not increase the self-weight and cross-sectional size of the reinforcement components. It has a wide range of applications and is widely used in the reinforcement and repair of various structural types and shapes such as buildings, bridges, tunnels, etc., as well as seismic reinforcement and structural reinforcement of nodes. The construction is convenient, no large machinery and equipment is required, no wet work is required, no fire is required, no on-site fixed facilities are required, the construction takes up less space and the construction efficiency is high. High durability, because it will not rust, it is very suitable for use in environments with high acid, alkali, salt and atmospheric corrosion.
High performance carbon fiber cloth
High performance carbon fiber cloth
It is suitable for the reinforcement and repair of various structural types and various structural parts, such as beams, plates, columns, roof trusses, piers, bridges, cylinders, shells and other structures. It is suitable for the reinforcement and seismic reinforcement of concrete structures, masonry structures, and wooden structures in port projects and water conservancy and hydropower projects. It is especially suitable for the structural reinforcement of complex forms such as curved surfaces and nodes. The strength requirement of base concrete is not less than C15. The construction environment temperature should be within the range of 5 to 35°C, and the relative humidity should not be greater than 70%.
In view of the many excellent properties of carbon fiber mentioned above, the application scope of carbon fiber is getting wider and wider. From the 1950s, it was mainly used in cutting-edge science such as rockets, aerospace and aviation, to the 1980s, it was widely used in sports equipment, textiles, chemical machinery and medical fields. At the same time, with the emergence of high-performance and ultra-high-performance carbon fiber, its application scope is becoming wider and wider, such as A380, Boeing 777, and new American main battle tanks, where carbon fiber accounts for more than 15%. At the same time, with the popularization of carbon fiber processing technology, its application scope has gradually involved civilian applications since the 1980s. So far, my country’s various applications account for 30% of carbon fiber demand in sports, 10% in aviation, and 60% in industry.
Carbon fiber for sports is mainly used in golf clubs, tennis rackets, racing cars, bows and arrows, jumping poles, ice hockey sticks, yachts, rowing boats, gliders, human-powered aircraft, sailboat masts, motorcycles and mountaineering supplies, such as trekking poles, ski poles, and rock climbing helmets. wait.
Trekking poles made of carbon fiber have high strength, light weight (50-80g lighter than aluminum walking poles), good rigidity, fatigue resistance, dimensional stability, and excellent energy absorption and earthquake resistance. Trekking poles made of carbon fiber can achieve the same effect as aluminum canes with shock-absorbing devices without installing shock-absorbing devices. More importantly, carbon fiber canes are highly rigid and can recover quickly after being bent with force. Aluminum After the cane is bent with force, plastic deformation occurs and cannot be restored. Carbon walking sticks have high fatigue strength and therefore long service life.
In view of the above many advantages of carbon fiber walking poles and the gradual improvement of production technology, I believe that the majority of mountaineering enthusiasts will like and promote them more after experiencing them for themselves.
