Wood Spars Mast and Spars Choices Materials and Mechanical Properties: The document outlines various types of wood used for masts and spars, including Glulam, Picea (Spruce), Oregon Pine (US), Douglas Fir (UE), Red Pine, and Larch. Each type is evaluated based on mechanical properties, durability class, assembling quality, and price costs.
Wood Types and Characteristics:- Picea (Spruce): Rated with three stars for nautic scarf assembling, indicating good mechanical properties and durability.
- Oregon Pine (US): Also rated with three stars for nautic scarf assembling, suggesting similar qualities to Picea.
- Douglas Fir (UE): Uses industrial joint assembling, rated with two stars for mechanical properties and durability.
- Red Pine: Similar to Douglas Fir, uses industrial joint assembling with two stars for properties.
- Larch: Uses simple joint assembling, rated with one star for mechanical properties and two stars for durability.
Assembling Types: The document includes photos of different assembling types such as nautic scarf, finger joint, and simple joint. Nautic scarf is noted for better flexion resistance and certified standard resistance, while simple assembling offers basic resistance.
Conclusion: The document provides a comparative analysis of different wood types for masts and spars, focusing on their assembling methods and mechanical properties. It serves as a guide for selecting the appropriate wood based on specific needs and budget considerations.
