Boron fibers are characterized by which property?

• A. Have a high bending stiffness, and cannot be easily woven into cloth or used for complex contoured parts
• B. Highly flexible and easy to weave into cloth
• C. Low stiffness and brittle
• D. Used mainly for insulation

Answer: (A)

Boron fibers are tested for their stiffness and formability. They have an exceptionally high bending stiffness, meaning they resist bending a lot. This makes them hard to drape, weave into cloth, or form around complex contours. They’re also brittle, so bending and shaping can lead to cracking. This combination explains why they’re not used for flexible fabrics or intricate shapes, and why the description of having high bending stiffness and being difficult to weave or contort best fits boron fibers.
