Fiberglass chopped felts, in fabric form, are usually sold in rolls and small folded packages.It is randomly oriented from 1 '-2' and is often used with a styrene water-soluble binder, which ACTS similar to connecting a fiber bundle with a gel.The binder is designed to dissolve in contact with styrene in polyester resin or vinyl ester resin.Once dissolved, the fabric softens, allowing it to drape around the curved shape.It weighs between 0.75 and 3 ounces per square foot.The most grams used are 0.75 and 1.5 ounces.In the United States, short cut felt is almost always sold or per square foot ounce rule.This is different from glass fiber cloth and glass fiber fabric and directional fiber layer (including weaving cloth, stitching biaxial & triaxial fabric, etc.).These are specified in ounces per square yard.When the short cut blanket is connected to any of these fabrics (such as in fabmat or biaxial pads), the incorporated fabric is often referred to as in the fabric weight.Can epoxy resin be used to infiltrate short cut felt?The answer is yes.Glass filaments are wetted in felt with epoxy resin, but the binder holds things together that don't dissolve.(it is put into a suspension and sealed in a cured epoxy resin.)This undissolved adhesive causes the soaked mat to remain somewhat stiff compared to being soaked with styrene resin.For items that are slightly bent or flat, such as the cabin floor or plywood deck, the mat and epoxy should work normally.Plastic sheets can also be used in uncured epoxy and felt to compress fibers.Residual air bubbles can be removed by puncturing or cutting through the plastic before the foam begins to solidify.When choosing fiber chopped blankets that can be used with epoxy resin, look for cushions that are soft and pliable.Some forms are quite stiff, and using epoxy resin can cause wetting problems.Hard felt tends to be old stock and the fibers may need more time to soak the epoxy resin.
