When using woven roving, what benefit does the increased material in the warp direction provide?

The correct choice reflects a key characteristic of woven roving in composite applications. When the material is oriented in the warp direction, it results in an increased density of fibers that helps to enhance tear strength in that direction.

Tear strength is particularly important in applications where the composite material may be subjected to stress that could cause tearing. The alignment of fibers in the warp direction allows for better distribution of forces acting on the surface, thereby improving the material's resistance to tearing.

While it's true that various factors like bonding with resin, flexibility, and abrasion resistance also play roles in the performance of woven roving, the specific structure and orientation of the fibers primarily contributes to tear strength. This characteristic makes woven roving a popular choice in applications requiring durable and robust composites.
