1. A method of manufacturing a structural element of fiber reinforced synthetic composite material, comprising the steps:

  • a) arranging respective fiber textile semi-finished materials respectively on plural carriers, which respectively have carrier contours that correspond to a positive or a negative of at least a portion of respective preform contours of respective preforms that are to be produced;

    b) applying a binder respectively to said semi-finished materials, and fixing said semi-finished materials respectively with said binder to form thereof respective semi-finished articles;

    c) removing said carriers from said semi-finished articles to form thereof said respective preforms having said respective preform contours, which respectively correspond to a positive or a negative of respective portions of a structural element contour of said structural element that is to be manufactured;

    d) arranging said preforms together with one another, and compacting said preforms;

    e) before, during or after said step d), impregnating said preforms with a matrix material comprising a curable resin; and

    f) after said steps d) and e), curing said matrix material comprising said curable resin, to bond together, stiffen and harden said preforms, and thereby to form thereof said structural element having said structural element contour.
