why radial fibers are more popular and widely used in the composites market?

There are a few key reasons why radial fibers are more popular

and widely used in the composites market?

• Suitability for tubular structures: Radial fibers are ideal for reinforcing tubular and cylindrical composite parts like pipes, tanks, tubes, etc. The spoke-like arrangement provides excellent hoop strength.
• Ease of manufacture: Radial fibers are easier to manufacture compared to other orientations. Simple filament winding techniques can be used to accurately deposit radial fibers during fabrication.
• Load distribution: Radial fibers effectively distribute loads and stresses throughout the composite part wall, preventing localized stress concentrations.
• Resistance to bursting: The hoop strength provided by radial fibers makes composites much more resistant to burst failure under internal pressure loads.
• Cost effectiveness: Radial fiber reinforcement is cost-efficient compared to other approaches like using multiple layers of unidirectional fibers. Less raw material is required.
• Impact resistance: Radial fiber composites have greater damage tolerance and impact resistance versus hoop winding orientation.
• Delamination resistance: Radial fibers act as a bridge to resist delamination or crack propagation between laminate layers.
• Versatility: Radial fiber reinforcement works for many different matrix materials like epoxy, vinyl ester, polyester, etc.
