What are the friction challenges when interlocking rattan strips without adhesives?

Interlocking rattan strips without adhesives presents several friction-related challenges that can affect the durability and aesthetics of the final product. Rattan, a natural material, has a smooth surface that reduces friction, making it difficult to achieve a secure interlock. The lack of adhesives means relying solely on mechanical friction, which can lead to slipping or loosening over time.

Key challenges include:

1. Surface Smoothness: Rattan's naturally polished surface reduces grip, requiring precise weaving techniques to enhance friction.

2. Moisture Sensitivity: Humidity can cause rattan to expand or contract, altering friction levels and potentially weakening interlocks.

3. Tension Management: Uneven tension during weaving can create weak points where friction is insufficient to hold strips together.

To address these issues, craftsmen often use techniques like scoring the rattan surface to increase roughness or employing tighter weaving patterns to boost friction. Understanding these challenges is essential for creating durable, adhesive-free rattan products.
