Due to the wide resources of bamboo, rapid growth of bamboo, high strength, and stable performance, many domestic and foreign furniture companies are currently focusing on the development of bamboo furniture. With the advancement of modern manufacturing technology, the shape and materials of bamboo furniture have been improved. More possibilities. China's main bamboo furniture production areas include Hunan Yiyang, Sichuan Kaixian, Zhejiang Anji, Fujian Zhanggui, etc. The variety of bamboo furniture produced in these areas is very rich, such as bamboo back chairs, bamboo stools, bamboo beds, bamboo screens, bamboo tables Wait. Because bamboo has excellent and stable elasticity, weave bending characteristics and weave compressive and tensile strength, so in the development process of bamboo furniture, bamboo bending technology is more and more widely used in modern bamboo furniture.
Bamboo bending furniture is roughly divided into round bamboo furniture, bamboo laminated wood furniture, reorganized bamboo furniture, and bamboo curved glued furniture due to the difference in product structure and processing materials.
Bamboo / Steel
The air chair designed by Pin logistics company is made of several curved bamboo strips to form a sitting surface that fits the sitting position of the human body. The structural support of the chair is made of stainless steel tubes. The shape of the whole chair is like a flower petal, giving a light and smart feeling. As the designer described his work, this chair is a special interpretation of traditional Chinese bamboo weaving. This concept chair reveals the limits of the weight and strength of bamboo, and the result is its lightness and durability.
Bamboo / Cement
This bamboo stool named "Ching", designed by Taiwanese designers Lin Ta-Chih and Hsieh Yi-Fan, combines green bamboo and cement, joining two completely different materials together. The designer believes that the original material deserves to be respected, so they use the design to redefine the meaning and relationship between the two materials, thereby expressing the beauty of the craftsmanship of the raw material, making it show a pure feeling. At the time of production, the designer drilled the part, bent the part under heating, and then cast the hourglass-shaped tenon-and-mortise hole on the part with cement, and connected the bamboo parts together with cement connectors.
Taiwanese designer Fan Chengzong collaborated with craftsman Chen Gaoming to develop a bamboo chair named "Flow". The designer used the bending process of bamboo to give it a natural sense of flow and create this piece of furniture with vitality and dynamics. .
Bamboo furniture bending process
Bamboo curved furniture is usually compounded by a number of bamboo bending members and connectors, showing a soft and curvy shape. However, due to the different units of bamboo furniture, the processing methods also differ. According to different classifications of furniture materials, the curved members usually have different forms such as round bamboo tube, bamboo strip, bamboo lintel, and bamboo composite material.
>>> Bending process of round bamboo tube
The bending process of round bamboo tube usually has two types of heating bending and slot bending, of which heating bending is the most common. In the process of heating and bending, the natural texture and texture of bamboo are not easily damaged, and the strength is not likely to be changed. The main method is to straighten the bamboo tube, apply a certain temperature to the part to be bent and slowly bend it, and then cool it with cold water to set it. In industrial production, it often takes the form of high temperature steam hot bending.
There are many forms of slotted bending, including common bamboo bending, square bending bending and corner bending. Based on the higher flexibility and tensile strength of the bamboo material, corners are usually sawn in the bending recesses and heated to soften the bending to achieve the target effect.
>>> Bending process of bamboo strips and bamboo strips <<<
Bamboo strips mainly refer to long bamboo sheets of fixed specifications after longitudinal processing along the grain. The bamboo sheet is cut to form long and narrow sheets with bamboo green and bamboo yellow. There are two methods for bending the bamboo strips and bamboo sheets: pressure bending as a whole and bending bamboo laminates. The first is to bend the bamboo strips with a mold and press them to bend, and then the bent bamboo strips are connected to the connector to make a curved furniture module. The second is to bend the bamboo strips and then splice them to form a small curvature. Simple curved parts.

Bamboo slugs are thinner sheet units formed by longitudinal cutting of bamboo flakes. They also have a long history of application in China. Commonly used mats and chairs in household products are made of bamboo slugs. The bamboo silk is a long filament-shaped unit processed from bamboo chips or bamboo rafters. The bamboo silk is often combined with a variety of household products using a weaving process, showing the beauty of harmonious and natural lines. Due to the relatively small unit size of bamboo shrews and bamboo filaments, natural mechanical forms are often used to bend and fix the materials when they are bent, or they are heated and bent.

The bending of bamboo veneer is more limited. Because the stability and strength of bamboo veneer after processing and splicing are slightly lower than the original bamboo, bamboo veneer is generally used for bending parts with small curvature, and the corners are Relatively more materials, so less in practical applications.
China has a vast land, rich bamboo resources, and a strong bamboo culture. Contemporary designers should make full use of their characteristics to develop new products after understanding the characteristics of bamboo materials. The bending process of bamboo materials has also brought more innovations to the development of modern bamboo furniture. The possibility of combining modern advanced manufacturing technology with the natural characteristics of bamboo to develop curved bamboo furniture has great potential.
