Definitions

  • the present invention relates to a sandwich panel used as an interior finishing material for a train and ship, and in particular to a semi sandwich panel which has a certain lightness and strength and is fabricated at a lower cost.
  • an interior finishing material which is used for a train and ship formed of a metallic material is fabricated at a lower cost.
  • a complicated product may be fabricated using the above material. In this case, it is easier to maintain the train and ship.
  • the train and ship having an interior formed of a metallic interior finishing material is easily rotten. So, the life span is short. The total weight of the train or ship is increased due to the metallic interior finishing material. Therefore, in order to overcome the above problems, a surface finishing material and core material formed of a textile are overlapped and bonded using an adhesive for thereby fabricating a sandwich panel which is used as an interior finishing material in the train and ship.
  • the above sandwich panel is lighter than a metallic panel and has a better strength with respect to its weight and a better durability.
  • a semi sandwich panel in which a core material is inserted into a portion which needs a strength and intensity between both surface finishing materials formed of a textile.
  • the surface finishing material is formed of more than one material selected from the group formed of a glass fiber, a carbon fiber, a synthetic fiber, and an aramid fiber.
  • the core material is formed of more than one material selected from the group formed of an aluminum honeycomb, a nomex honeycomb, a paper honeycomb, a urethane foam, and an acrylic foam.
  • the insert nut is installed in the core material formed between both surface finishing materials for implementing a mounting structure.
  • FIG. 1 is a perspective view illustrating a semi sandwich panel according to a first embodiment of the present invention
  • FIG. 2 is a cross-sectional view taken along line A-A of FIG. 1;
  • FIG. 3 is a cross-sectional view illustrating a mounting structure of a semi sandwich panel of FIG. 1;
  • FIG. 4 is a perspective view illustrating a semi sandwich panel according to a second embodiment of the present invention.
  • FIG. 5 is a cross-sectional view taken along line B-B line of FIG. 4;
  • FIG. 6 is a cross-sectional view of FIG. 4.
  • FIGS. 1 through 3 are views illustrating a semi sandwich panel which is used as an interior finishing material for a train according to a first embodiment of the present invention.
  • a core material 14 is formed into a portion which needs a certain strength and intensity between both surface finishing materials 12 formed of a textile for thereby forming a semi sandwich panel 10 .
  • FIGS. 4 through 6 are views illustrating a semi sandwich panel for an interior finishing material of a train according to a second embodiment of the present invention and illustrating a semi sandwich panel in which a window frame is integrally formed.
  • a glass fiber is impregnanted into a phenol or epoxy resin for thereby producing a prepreg.
  • the prepreg is disposed on a mold or a molding base.
  • a core material 14 is partially inserted into an edge portion of the inner surface of the surface finishing material 12 and a circumference of the window frame 10 a in a rib shape based on a known method for implementing a certain strength and intensity and is molded at a high temperature or is fabricated based on a hand lay up method at a room temperature and is hardened for thereby fabricating a semi sandwich panel 10 .
  • the insert nut is installed in the core material 14 in the same manner as the first embodiment of the present invention.
  • the core material 14 is formed of more than one material selected from the group formed of an aluminum honeycomb, a nomex honeycomb, a paper honeycomb, a urethane foam, and an acrylic foam.
  • the core material 14 which is partially filled between both surface finishing materials 12 , namely, is filled into a portion which receives a stress and needs a certain strength and intensity.
  • the core material 14 is partially inserted between both surface finishing materials 12 in various shapes based on the shape and purpose of the interior finishing material.
  • the core material which forms a structure of the sandwich is partially formed in an edge portion of the panel which needs a strength and intensity between both surface finishing materials and in a rib shape across the edge portions or in the case of the window frame, the core material is formed in an edge portion of the panel and the circumference of the window frame in a rib shape for thereby decreasing the use of the core material compared to the conventional sandwich panel, implementing a desired strength, intensity and durability and decreasing the fabrication cost.
