Japanese Patent JPH06504743
Kind Code:
A
Abstract:
A method for continuously manufacturing a composite sandwich structure by pultrusion through a pultrusion die comprises arranging fiber reinforcement materials on the surface of a preformed foam core, applying liquid resin to the reinforcement materials on the surface of the foam core, heating the surface region of the foam core to a temperature of at least 100 degrees C. to convert water in the foam core to steam, thereby causing water vapor pressure expansion of the foam, and using the expansion of the foam core to subject the liquid resin to increased pressure.
