Filament Winding

Johns Manville rovings for filament winding are proven reinforcements for composite pipes, silos and tanks.

StarRov® 086 is characterized by a soft silane sizing compatible with unsaturated polyester, vinylester and epoxy resins. Direct rovings with 086 sizing are easy to unwind with very low fuzz generation during processing, excellent wet-out in the matrix resin and superior fatigue characteristics in the composites.

StarRov® 908 is characterized by silane sizing most suitable for reinforcement of epoxy, vinylester and unsaturated polyester resins.  Direct rovings with 908 sizing are easy to unwind with even tension. The wettability of the direct rovings with 908 sizing is excellent.

StarRov® 076 is manufactured by direct winding of continuous glass fibers of defined diameter into a cylindrical roving package. This product is characterized by a soft silane sizing compatible with unsaturated polyester resin, vinylester and epoxy resins.  Direct rovings with 076 can be used for filament winding.
