Fiberglass rod - 4 mm x 100 cm

Professional Structural Core for Cosplay and Props

This high-quality fiberglass rod is a versatile structural essential designed for demanding cosplay projects and prop making. Measuring 4 mm in diameter and 100 cm in length, it provides the perfect balance between mechanical strength and low weight. Whether building rigid armatures or reinforcing intricate costume elements, this material ensures that structures remain stable and resilient throughout intensive use.

Key product features

• Optimized dimensions: The 4 mm diameter and 100 cm length make this fiberglass rod ideal for medium-sized projects requiring precise internal reinforcement. Its compact profile allows for easy concealment within foam layers or fabric structures.
• High flexibility: The material features excellent elasticity, allowing for controlled bending without the risk of cracking or permanent deformation. This flexibility is essential for creating dynamic prop shapes that need to absorb impacts during movement.
• Lightweight composition: Significantly lighter than metal alternatives, this fiberglass rod minimizes the overall weight of finished props and costumes. This feature is crucial for maintaining comfort during long hours at conventions or LARP events.
• Easy fabrication: The rod can be easily trimmed to a specific length using a hacksaw or rotary tool. Users benefit from a material that is simple to integrate into complex designs while adhering to standard workshop practices.
• Strong adhesion: Featuring a specialized surface structure, the rod ensures reliable bonding with various materials. It works exceptionally well when secured inside EVA foam using contact adhesives or cyanoacrylate glues.

Common applications

• LARP Weapon Cores

  The 4 mm rod serves as an effective, flexible core for light LARP weaponry such as daggers, short swords, and wands. It provides necessary structural integrity for the foam blade while offering enough "give" to ensure safe engagement during reenactments.

• Costume Armatures

  Ideal for creating stable frameworks for wings, antennae, or extended costume features. The rigidity of the fiberglass allows for the support of heavy decorations or fabric layers without adding unnecessary bulk to the wearer’s frame.

• Prop Reinforcement

  Used widely in modeling and diorama making as a durable internal skeleton. The material’s resistance to moisture and corrosion ensures that interior structural supports remain intact and stable, even in long-term display projects.

To achieve the most durable connections when embedding these rods into foam, consider using professional cyanoacrylate glue for an instant bond. Explore our complete range of tubing and structural materials to find the perfect components for your next ambitious build.
