1. method that is used to make the plate-like fibre rein-forced composite product that can be used as construction material or packaging material, this method comprises:

  • Fiber is placed on the lower laminate,The foaming sclerosis bonding agent that is in a liquid state is coated on this fiber, thereby these fibers is surrounded by this bonding agent,To between bottom and top hold-down, carry at the fiber that has bonding agent between lower laminate and the upper laminate, and bottom and top hold-down are configured to rotate in the upside and the downside cocycle of the fiber that has bonding agent respectively, thereby the rotating speed by this pressing plate is carried the fiber that has bonding agent, andAllow bonding agent between the pressing plate of upper and lower, to foam, expand and harden, it is characterized in that comprising the steps;

    This fiber production is become the three-dimensional cohesion fibre mat that constitutes by the fiber that bonds together, and then bonding agent is coated on this fibre mat, the thickness of this fibre mat is basically between 0.5 and 0.8 millimeter, width is between 0.3 and 2 millimeter, and the length of at least 80% fiber is at least 100 millimetersBefore being coated to bonding agent on the fibre mat, make the water capacity of this fibre mat be at most 5%,Bonding agent is coated on the fibre mat, thereby obtain the mixture of fibre mat and bonding agent, this mixture comprises the fiber near the fiber of its upper surface and close its lower surface, and the fiber of close its upper surface is against top hold-down, the fiber of close its lower surface is then against the bottom pressing plateWhen between pressing plate, carrying this mixture, this mixture is placed be at least 0.8 crust and mostly be most under the pressure of 5 crust, and to allow this mixture cures to become thickness be 10 to 150 millimeters and comprise near the fiber of its upper surface with near the plate-shaped products of the fiber of its lower surface, andBottom and upper laminate are removed from the sclerosis goods that include fiber and bonding agent.
