Wholesale E-Glass Fiberglass Chopped Strand Mat for Rtm Process

In terms of production technology, the production process of fiberglass felt includes steps such as impregnation, molding, compression, curing, exhaust, and polishing. Firstly, soak the fiberglass cloth or felt in the resin to allow the fibers to fully absorb the resin. Then, place the impregnated fiberglass cloth or felt into the prefabricated mold and machine press it into shape. Next, by compressing to remove excess resin and air, the glass fibers are made tighter. Subsequently, the compressed glass fiber is placed in an oven or cured at room temperature until the resin is completely hardened. Finally, perform exhaust and polishing treatment to make the product surface smooth and beautiful.

Let's take a look at the characteristics of fiberglass felt. Compared to fiberglass chopped felt, fiberglass felt has a longer fiber length and typically exists in the form of continuous fibers. This gives glass fiber felt significant advantages in mechanical properties and stability. In addition, fiberglass felt also has many characteristics such as high heat resistance, good insulation performance, high sound absorption rate, high exhaust purification efficiency, corrosion resistance, insect resistance, mold resistance, low absorption rate, good vibration resistance, flame retardancy, and light warranty. These characteristics make fiberglass felt have broad application prospects in multiple fields.
