  • Composites made of fiber reinforced resin elements joined by adhesive
    Patent number: 4966802
    Abstract: Fiber reinforced resin composites formed by elements joined by a high shear strength, high fracture toughness adhesive are disclosed. The elements are created in easily produceable cross-sectional shapes such as flat, C-shaped, Z-shaped or T-shaped. When joined, the elements form delamination resistant fiber reinforced resin composites having more complex shapes. The strength of the junctions between a pair of elements, such as a panel and its associated reinforcing members, can be enhanced by fasteners, such as rivets, if desired.
    Type: Grant
    Filed: May 16, 1989
    Date of Patent: October 30, 1990
    Assignee: The Boeing Company
