A radial fiber, also known as a radial-reinforced fiber or a spoke fiber, is a type of reinforcement fiber used in the construction of fiber-reinforced polymer composites. It is characterized by its orientation, which is radial or perpendicular to the circumferential direction of the composite structure.
Radial fibers are commonly used in the manufacturing of cylindrical or tubular composite structures, such as pipes, pressure vessels, and tanks. They are arranged in a spoke-like pattern, extending radially from the center of the structure towards the outer circumference.
The primary function of radial fibers is to provide hoop strength and resistance to radial deformation or splitting. They help to transfer loads and stresses from the matrix material to the reinforcing fibers, improving the overall strength and stability of the composite structure.
Radial fibers are often used in combination with circumferential or hoop fibers, which provide additional strength and stiffness in the circumferential direction. Together, these fiber orientations create a robust and well-balanced reinforcement system capable of withstanding various loading conditions.
There are a few key reasons why radial fibers are more popular and widely used in the composites market:
