Low density, polybutadiene based, wet filament winding resin

摘要

Disclosed are wet filament winding resins that are intimate admixtures consisting essentially of polybutadiene polymers whose functionality resides solely in unsaturation, an unsaturated monomer component, a peroxide free-radical initiator and optionally a block copolymer impact modifier. The resins have long pot lives and cure into low density resin matrices in composite structures. The resin matrices can have select mechanical properties of desired character through ingredient choice.
