Are glass fiber parts affected by heat?

Yes, glass fiber parts can be affected by heat, but they generally have good heat resistance compared to other materials. Fiberglass can withstand moderately high temperatures without significant damage; however, extreme heat, such as that produced by engine components or exhaust systems, may cause the material to soften, warp, or lose its structural integrity over time. Proper installation and heat shielding are important to ensure that fiberglass parts are protected from direct exposure to excessive heat.
