The tensile strength of black fiberglass tissue can vary depending on the specific type and manufacturing process. Generally, it ranges from 500 to 3000 MPa (or 72,500 to 435,000 psi). This high tensile strength makes it suitable for applications requiring high strength-to-weight ratios, such as in construction, automotive, and aerospace industries. It's important to note that the exact tensile strength should be obtained from the manufacturer's specifications for the specific product in question.
