  • Composite system and method for reinforcement of existing structures
    Patent number: 6599632
    Abstract: A method of reinforcing an external surface of a structural member including the steps of applying to a surface a fiber reinforced polymer system, and curing or hardening the polymer system. The polymer system is characterized by including a single-phase homogenous system before curing or hardening and becoming a two-phase system upon curing. The polymer system results in, when cured, a structural polymer including a continuous phase and an elastomeric polymer discontinuous phase.

  • Thermally fused thermoplastic honeycomb structures
    Patent number: 5635273
    Abstract: A method and apparatus for forming a honeycomb structure in which a plurality of thermoplastic layers are fused together at selected locations. The thermoplastic layers at each of the selected locations are melted together to form a welded portion which includes first and second exterior surfaces. The welding of the thermoplastic layers is controlled so that no more than one of the exterior surfaces is melted. This partial melting of one layer prevents undesirable welding to adjacent layers. An apparatus for carrying out the method for welding thermoplastic honeycomb structures is also disclosed.
