Latest Patents
One of Bruce A Stern's latest patents is a bis-maleimide resin composition. This innovative matrix resin composition comprises 40 to 95 percent by weight of ethyleneically unsaturated bis-imides, which include a mixture of maleimides of aromatic amines and a minor portion of maleimide of an aliphatic amine. Additionally, it contains 5 percent to 60 percent by weight of a heat-activatable cross-linking agent combination, which is essential for gelling the bis-imides. This resin composition is particularly useful for high-performance, fiber-reinforced composites, offering low shrinkage, good thermal stability, moisture resistance, and excellent impact strength.
Another significant patent by Stern involves high impact strength fiber resin matrix composites. This invention discloses improved fiber resin matrix prepreg fabrics, which consist of a first layer of reinforcing fabric coated with an epoxy resin composition and a discrete second layer of an epoxy resin modified with an elastomeric polymer. The second layer is supported by a lightweight fibrous mat that preserves its integrity during the curing process. The resulting cured composites exhibit high impact strength and resistance to impact damage.
