Multilayer stitched knitted fiberglass composite

DETAILED DESCRIPTION One object of this invention is to overcome the above-noted defects.
Another object of this invention is to provide a structural fabric which is lightweight and relatively inexpensive to prepare.
Yet another object of this invention is to provide a structural fabric which can be employed wherever high strength and lightweight materials are desirable, such as the aeronautic, automotive and marine industries.
It is another object of this invention to provide a structural fabric which is useful, whether employed alone or laminated with other materials, in the manufacture of skis.
The objects of this invention can be accomplished by using a double biased, three-layer fabric which is provided by affixing a first layer of biased, substantially parallel structural fibers to a second layer of substantially parallel structural fibers aligned at an angle of approximately 90.
degree.
to those of the first layer and of approximately twice the weight of those of the first layer, and further affixing a third layer of parallel structural fibers aligned at the same angle as those of the first layer, and of approximately equal weight of those of the first layer.
