ABSTRACT OF THE DISCLOSURE The present invention relates to a continuous process of forming an elongate pressed composite assembly from a plurality of elongate strands by subjecting the strands to heat and pressure, as well as to the product obtained therefrom. In the process, a first lay-up containing a plurality of strands in generally parallel, longitudinally aligned relationship and a generally random overlapping relationship in which succeeding strands generally overlap only a portion of the preceding strands is formed. Such formation results in strands that, on the average, are angled above the horizontal. A second such lay-up is formed and one of the lay-ups is then inverted and positioned on top of the other to form a composite mat. When the composite mat is conducted through a compressing zone of a press, the internal stress in each half of the assembly due to the angle at which the strands are stacked is offset by the internal stress in the opposing half of the composite assembly. The mat, if desired, may contain three, four or more lay-ups.
