allows the formation of the fiber reinforced metal sheet of the present invention is shown by a region surrounded by the y axis and lines a b and c the thickness of the sheet obtained by the method of the present invention was 0 35 mm when the irradiation power of the laser beam is excessively high the wire preforms are extremely damaged when the irradiation power is too low the wire preforms can not be sufficiently joined temperature rise in the wire preforms is controlled by the irradiation power of the laser beam and the pressing speed as a comparative example a fiber reinforced metal sheet was prepared by irradiating with a single laser beam in this case there was found a condition permitting the joining in a range of the power density of the co 2 laser beam of 1 3 u00d7 10 7 w m 2 and the power density of the yag laser beam of 1 3 u00d7 10 6 w m 2 in comparing the comparative example with the above mentioned embodiment of the present invention a fiber reinforced metal sheet can be prepared by a relatively low power density of laser beam in the present invention in the above mentioned embodiment the laser beam having a linear distribution of power density is used however the same effect can be obtained by using a laser beam having a trapezoidal distribution of power density the focusing device for focusing the laser beam may be a lens a mirror or a driving type mirror as far as a predetermined distribution of power density can be obtained although it.
