Fiberglass rod - 4 mm x 40 cm

Reliable Structural Core for Props and LARP Weaponry

Designing advanced props requires materials that balance low weight with high mechanical strength. This fiberglass rod, measuring 4 mm in diameter and 40 cm in length, provides an excellent foundation for reinforcing armor elements and creating frames for lightweight safe weaponry. It is an indispensable component for building EVA foam structures, ensuring stability and long-lasting durability for even the most ambitious cosplay projects.

Key Features

• Optimal 4 mm Diameter: This precise thickness allows for easy integration within thin layers of foam or other modeling materials without adding excessive bulk. It provides the ideal balance between essential structural rigidity and necessary flexibility.
• Practical 40 cm Length: The convenient size makes this rod perfect for smaller construction elements such as daggers, wands, or intricate armor details. The length can be easily trimmed to fit specific project requirements using standard workshop tools.
• High Durability and Elasticity: Crafted from fiberglass, this rod remains virtually unbreakable under standard use. It exhibits excellent memory, meaning it returns to its original shape after bending, effectively preventing deformation in complex cosplay designs.
• Lightweight Construction: Low weight is a critical factor when building large, multi-piece costumes or weaponry used throughout long conventions and LARP events. Structures reinforced with these rods do not unnecessarily strain the hands or weigh down the overall costume.
• Excellent Bonding Properties: The surface of the rod ensures high adhesion when used with professional mounting adhesives. It creates a seamless and permanent bond with synthetic foams and thermoplastics, resulting in a cohesive structure.

Applications

• LARP Weapon Cores

  Smaller swords, daggers, and throwing knives require a stable and safe skeleton that effectively absorbs impact energy. This fiberglass rod prevents the foam from sagging, ensuring the weapon remains safe and retains its realistic shape during dynamic skirmishes.

• Armor Reinforcements

  Large armor components, such as pauldrons, greaves, or protruding chest plate details, can lose their shape under their own weight. Inserting these rods inside foam layers helps maintain the desired profile, keeping the armor rigid yet flexible during movement.

• Complex Structural Frames

  Moving or static elements of fantastical creatures often require a lightweight internal frame. These rods are ideal for creating structural ribs in wings, tail armatures, or mountings for feathers, providing a sturdy shape without adding unnecessary mass to the costume.

For permanent assembly, it is recommended to use professional mounting chemicals, such as cyanoacrylate adhesives, to ensure a rapid and durable bond.
