FIBER REINFORCED FOAM COMPOSITES DERIVED FROM HIGH INTERNAL PHASE EMULSIONS |
摘要 |
<p>The invention relates to foam composites having improved properties. These polymeric foams are prepared by polymerization of certain water-in-oil emulsions having a relatively high ratio of water phase to oil phase, commonly known in the art as high internal phase emulsions, or "HIPEs." The HIPE-derived foam materials used in the present invention comprise a generally hydrophobic, flexible, semi-flexible, or rigid nonionic polymeric foam structure of interconnected open-cells. These foam structures have a density of less than about 100 mg/cc, a glass transition temperature (Tg) of between about -40° and 90° C., and at least about 1% by weight compatible fibers incorporated into the foam. The foam composites have improved tensile properties compared to foams having no incorporated fibers or foams having noncompatible fibers incorporated therein.</p> |
