This invention relates to a unitary composite laminate structure, particularly as it relates to the manufacture of macro-scale unitary composite laminate structures. The laminate structure of this invention comprises a unitary composite having an inner core layer and an outer encapsulating layer co-adhered one to the other by a bonding material. The respective inner core and encapsulating layers are chemically fused together to produce the unitary structure. A high shear strength, load-bearing matrix is disposed between the respective inner core layer and the outer encapsulating layer. The matrix is oriented substantially entirely in the load bearing direction so that the unitary composite structure is capable of resisting delamination under conditions requiring high tensile and high shear strength.

A unitary composite laminate structure comprising: an inner core layer and an outer encapsulating layer co-adhered one to the other by a bonding material for fusing together said inner and outer layers to produce said unitary structure, and a high shear strength, load-bearing matrix comprising a plurality of uncrimped, load-bearing synthetic filaments which are physically connected together to prevent movement of said filaments under load conditions, said load-bearing matrix disposed between said respective inner core layer, said outer encapsulating layer, being oriented substantially entirely int he load bearing direction, said unitary composite structure including means attached to said load-bearing matrix for absorbing forces imparted to said structure and thereby minimizing the effects of shear stress and being capable of resisting delamination under load conditions requiring high tensile and high shear strength, and said force absorbing means comprising a mat of synthetic fibers which are physically attached to said load-bearing matrix.
