  • Ordered polymer/sol-gel microcomposite laminates with peek resin adhesive
    Patent number: 5344703
    Abstract: Provided are methods for laminating ordered polymers such as PBZT/sol-gel glass microcomposite film layers by first roughing the bonding surfaces of such film layers and then inserting therebetween a PEEK resin adhesive layer and compressing the film and adhesive layers together at sufficient temperature and pressure to laminate such layers. In one embodiment the ordered polymer layers are hot-pressed before surface roughing, stacking and laminating of film and adhesive layers. The invention also includes the novel laminates prepared thereby which exhibit high tensile strength, high compressive strength and good interlaminar strength, suitable for high-performance structures in e.g. aircraft, spacecraft or other structures or vehicles.

  • Curing polyepoxide resin binders in syntactic foam forming compositions
    Patent number: 4412012
    Abstract: Disclosure is made of a method of curing the polyepoxide resin binder component of polyepoxide based syntactic foams. Ketones are employed to reversably block primary amine groups on polyamine curing agents during the initial curing. As the cure progresses, the block is removed to complete the cure. The result is a moderation of peak exotherms generally associated with the cure, inhibiting degradation of the product foam.

  • Bis-ethynyl heterocyclic compositions and method of synthesis
    Patent number: 4086232
    Abstract: Bis-ethynyl quinoxaline compositions are prepared by the condensation reaction of an aromatic diglyoxyl or dibenzil with an ethynyl-substituted aromatic ortho-diamine. The compositions are useful as polymerizable plasticizers for heterocyclic thermoplastic resins in the fabrication of composites. Polymerizable plasticizers are materials that remain fluid and act as a plasticizer during early stages of fabrication and then polymerize to a rigid resin.
