The density of black fiberglass tissue, also known as black glass fiber fabric, is typically measured in grams per cubic centimeter (g/cm鲁). It can vary depending on the specific type and weave of the fiberglass, but generally, it ranges from 0.2 to 0.4 g/cm鲁. This density is determined by the weight of the fibers per unit volume. To measure the density, one would weigh a known volume of the fiberglass tissue and divide the mass by the volume to get the density in g/cm鲁.
