Why Bamboo Is Hard With Good Toughness?

[vc_row][vc_column][vc_column_text]In-plant taxology, bamboo belongs to Gramineae, the bamboo subfamily. The appearance of bamboo is cylindrical, the pile height is 1-20 meters. Maybe many people think that bamboo is wood, in fact, bamboo belongs to grass. The bamboo stalk is rough and straight, bamboo lignification, they are visible slubs. The Inter-slubs are hollow. In recent years, bamboo is widely used, people processed raw bamboo into bamboo furniture boards and bamboo decorations. not only because bamboo is very eco-friendly, but also more important is due to the performance of bamboo is very good. Bamboo is very hard with good toughness.[/vc_column_text][vc_row_inner][vc_column_inner][vc_single_image image=”9072″ img_size=”large”][vc_column_text]Generally, the density of Mao bamboo in 4-5 years is about 0.7g/cm3. Density determines the hardness of the bamboo. and the density mainly depends on the contents of fiber, fiber diameter, and cell wall thickness. Density will increase with fiber content increasing.

Besides, the growth environment of bamboo also affects the density of bamboo. Thereby affecting the hardness of the bamboo. With the same species of bamboo in the warm and humid climate, fertile soil conditions, bamboo grows well. The bamboo stalk is rough and straight. the density will be higher, and conversely, the density side will be smaller.

The rigidity of bamboo is also very better compared to other woods. The hardness of bamboo can reach 32HB, which is higher than beech (23HB) and oak (24HB).[/vc_column_text][/vc_column_inner][/vc_row_inner][vc_row_inner][vc_column_inner][vc_single_image image=”9070″ img_size=”large”][/vc_column_inner][/vc_row_inner][vc_column_text]In accordance with the experimental determination, the longitudinal compressive strength of the bamboo material reached 80 M Pa. Generally, the carbonized bamboo products increase the hardness of the bamboo surface due to the coking of the bamboo fibers. However, the flexibility side of bamboo should be reduced.

The toughness of bamboo is also closely related to bamboo fiber. The fiber of bamboo is long and straight. Therefore, the shape variable of bamboo is very small, and the elasticity and toughness are very good. Determined by experiment, the tensile strength of bamboo can reach 170-180M Pa. Therefore, bamboo is often used to make skateboards or bows. bamboo is indeed an ideal material compared to other woods.

Bamboo is also according to the direction of the fiber during production processing, rarely destroys fiber. It greatly reduces the probability of water absorption, so it is not easy to expand or contract. In addition, bamboo plywood is cooked and dried through high temperatures. stable after installation.

The longitudinal compressive strength and tensile strength of bamboo are related to bamboo’s moisture content. That is to say, the hardness and toughness characteristics of bamboo are related to the moisture content of bamboo. The moisture content of bamboo has a certain relation with the age of the bamboo and the season of harvesting. Young bamboo has higher moisture content than older bamboo. The moisture content of bamboo harvested in summer is higher than that of other seasons.

It is precise because bamboo is hard with good toughness, Bamboo has become more and more widely used. bamboo will become a trend in the future.[/vc_column_text][/vc_column][/vc_row]
