Can fiberglass melt

Fiberglass itself does not melt in the traditional sense, as it is made from glass fibers that have a high melting point, typically around 1,200 to 1,500 degrees Fahrenheit (650 to 800 degrees Celsius). Instead, it can degrade or lose structural integrity when exposed to high temperatures. The resin used to bind the fiberglass can melt or burn at lower temperatures, which may compromise the material's overall properties. Therefore, while the glass fibers won't melt, the composite can be affected by extreme heat.
