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.

A method of making a delamination resistant fiber reinforced resin composite comprising the steps of:
- forming a fiber reinforced resin composite panel from a plurality of plies and a resin matrix;
- forming a fiber reinforced resin composite reinforcing member from a plurality of plies and a resin matrix;
- and,
- bonding said fiber reinforced resin composite panel to said fiber reinforced resin composite reinforcing member with a high shear strength, high toughness, thermosetting resin adhesive layer, said thermosetting resin being different from the resin used to form said resin matrix of said fiber reinforced resin composite panel and said fiber reinforced resin composite reinforcing member.
