What weight is most commonly used for woven roving in marine applications?

Woven roving is a type of reinforcement fabric often used in marine applications due to its strength and versatility. The correct weight commonly used for woven roving in this context is 24 ounces per square yard. This weight strikes a balance between providing adequate durability and maintaining the flexibility necessary for application on various surfaces, such as hulls and decks.

The 24-ounce weight offers sufficient structural integrity, making it popular for producing strong laminates and minimizing the risk of delamination when properly wet out with resin. Heavier weights, such as 36 ounces or 48 ounces per square yard, while offering more strength, can be cumbersome and more difficult to work with, especially in curved or intricate areas of a vessel. Conversely, a lighter weight, like 12 ounces per square yard, may not provide the same level of strength required for heavily loaded or high-stress areas. Thus, 24 ounces per square yard is the ideal choice for woven roving in marine applications, combining strength with manageability.
