The method of the invention involves depositing a plurality of thin layers of film, each layer having a thickness ranging from about 500 to about 2000. A receiving section is integrally disposed at the rear end of the insulative frame. Accordingly, only the modules which need upgrading can be selectively upgraded, so that it is possible to increase the efficiency of the upgrading. Still further, a multipurpose tool is provided that includes a handle defining a pocket for storing at least one bit in instances in which the bit is not engaged by the bit driver, thereby reducing the likelihood that the bit will be lost or otherwise separated from the multipurpose tool. Next the preformed composite laminate travels into a pultrusion die where the extended groupings of fiber filaments are all bent over above the top skin and below the bottom skin producing a superior clinched Z-axis fiber reinforcement as the composite laminate continues to be pulled, catalyzed, and cured at the back section of the pultrusion die.
