Muscle fibers can be found in muscle tissue. These cells are long and tubular, and muscle cells are developed from myoblasts.

After muscle formation, muscle cells will specialize into several types, including skeletal muscle, smooth muscle and myocardium. These muscles have their own functions and are responsible for different types.

Skeletal muscle is responsible for human movement; The myocardium is mainly responsible for the beating of the heart and the blood circulation of the whole body. Smooth muscle is related to human intestinal activity.

Fiber refers to a substance composed of continuous or discontinuous filaments. In animals and plants, fiber plays an important role in maintaining tissues.

Fiber has a wide range of uses, which can be woven into thin thread, thread end and hemp rope, and can also be woven into fiber layer when making paper or weaving felt; At the same time, it is often used to make other materials and form composite materials with other materials.

Fiber filling can effectively improve the strength and stiffness of plastics. Fiber reinforced plastics are rigid structural materials.

Fiber reinforced plastics have two main components. What is a matrix? Thermosetting plastics or thermoplastics filled with fiber materials. Pass? The strength of ordinary matrix is low, while the fiber filler is rigid but fragile.

In the reinforced plastic obtained by compounding the two, the fiber bears great load stress, and the matrix resin supports the fiber to transmit external load through the shear stress at the interface with the fiber.
