A conformable veil is formed by impregnating a random mat of glass fibers formed with a polystyrene-based resin. The veil is then introduced between two layers of a sheet molding compound resin paste and compacted to form a compacted sheet. The compacted sheet is then introduced to a mold and molded to form a soft, flexible sheet molding composite part having good resin and fiber distribution. Resin and fiber distribution of the present invention is improved because the polystyrene-based resin is soluble in the sheet molding compound resin paste and allows the plurality of fibers to flow freely within the resin paste during the molding process.

Fibrous veil for Class A sheet molding compound applications

Beads are made from water-soluble monomer or monomer blend by reverse phase bead polymerization by extruding aqueous monomer beads into or onto the top of an upflowing column of non-aqueous liquid and the beads polymerise as they float downwardly through the column during a period of at least &frac12; minute. The resultant beads can have a very narrow particle size distribution.
