1. A method, comprising:

  • introducing a band of fiber material impregnated with a resin to an apparatus comprising a band separating means and a pinmat, wherein the pinmat comprises a pin pattern having at least two directionally distinct sets of parallel rows of pins projecting from a surface, each one of the sets having a defined gap between each pair of adjacent rows;

    selecting one of the directionally distinct sets of parallel pin rows;

    separating the band to form a plurality of strips having a width less than or equal to the defined gap of a selected one of the sets;

    disposing the strips between the selected one of the sets of the parallel pin rows to form a layer of strips;

    repeating at least one time the steps of selecting one of the directionally distinct sets of parallel pin rows, separating the band, and disposing the strips to form a stacked structure comprising at least two layers of the strips, wherein the strips in adjacent layers have different directional orientations; and

    compressing and curing the stacked structure to effect adhesion of the at least two layers so as to form a composite laminate sheet comprising through-holes in a hole pattern corresponding to the pin pattern.
