How do you make composite bamboo?
How to bind bamboo? Bamboo is difficult to assemble due to its anatomical, physical and chemical attributes. Bleaching and plasma treatments improve bamboo wetting and bonding performance. Double molecular weight phenol-formaldehyde adhesives are efficient for bamboo bonding.
How do you make bamboo fiber?
There are two ways to process bamboo into a fabric: mechanically or chemically. The mechanical process includes crushing the wooden part of the plant and then applying natural enzymes to break down the bamboo cell walls, creating a mushy mass. The natural fibers can then be mechanically combed and spun into yarn.

What are the three general factors that determine the properties of a composite material?
Answer. Three factors are given in the test: (1) the materials of the components; (2) the geometric shapes of the constituents – the reinforcement phase in particular – and the resulting structure of the material; and (3) phase interaction.

What factors determine the properties of composites?
The mechanical properties of composite materials usually depend on the structure. Thus these properties typically depend on the form of inhomogenities, the volume fraction occupied by inhomogenities, and the interfaces between the components.

However, as a class of materials, composites tend to have the following characteristics: high strength; high modulus; low density; excellent resistance to fatigue, creep, creep cracking, corrosion, and wear; and a low coefficient of thermal expansion (CTE).
What are composites and its properties?
A composite material is a mixture of two materials with different physical and chemical properties. When combined they create a material that is specialized to do a certain job, for example to make it stronger, lighter or more resistant to electricity. They can also improve strength and stiffness.
What are composites?
A compound is a material made of two or more different materials which, when combined, are stronger than those individual materials alone. Simply put, compounds are a combination of components.
