Abstract
Disclosed is an automated fiber placement (AFP) device for preform manufacturing. The AFP device includes a feeder configured to feed a sheet-type fiber composite material, a molding part configured to mold a sheet-type structure by allowing a roller member to compress the sheet-type fiber composite material, and a compressing part configured to compress an upper surface of the structure, thereby disposing the sheet-type structure on a substrate in a state of maintaining the shape of the sheet-type structure. Particular, the compressing part moves from one end to the other end of the substrate, thereby compressing the sheet-type structure.
Claims17
An automated fiber placement (AFP) device for stacking fiber composite materials, comprising:
- a feeder configured to feed a sheet-type fiber composite material having a predetermined width;
- a molding part located downstream of the feeder, including a roller member in a curved shape, and configured to compress the sheet-type fiber composite material fed from the feeder by the roller member, thereby molding a sheet-type structure, the molding part comprising:
- a first roller member comprising:
- a first body portion having a cylindrical shape having a constant outer diameter along its longitudinal axis and configured to be rotatable by a first rotational shaft arranged along a width direction of the sheet-type fiber composite material, and
- a pair of first protruding portions, each of the first protruding portions having a cylindrical shape having a constant outer diameter along their longitudinal axes, located at either lateral side of the first body portion and each having an outer diameter greater than that of the first body portion;
- and
- a second roller member comprising:
- a second body portion having a cylindrical shape having a constant outer diameter along its longitudinal axis, located on an upper side of the first roller member in parallel with each other and configured to be rotatable by a second rotational shaft, and
- a second protruding portion having a cylindrical shape having a constant outer diameter along its longitudinal axis located on only one lateral side of the second body portion and having an outer diameter less than that of the second body portion;
- wherein the molding part is configured to press the fiber composite material in the direction of its thickness between one of the first protruding portions and the second protruding portion, between the first body portion and the second protruding portion, and between the first body portion and the second body portion;
- and
- a compressing part located downstream of the molding part, having a shape corresponding to a shape of an upper surface of the sheet-type structure, and configured to compress the upper surface of the sheet-type structure fed from the molding part, thereby disposing the sheet-type structure on a substrate in a state of maintaining the shape of the sheet-type structure,
- wherein the compressing part moves from one end to the other end of the substrate.

- a molding part located downstream of the feeder, including a roller member in a curved shape, and configured to compress the sheet-type fiber composite material fed from the feeder by the roller member, thereby molding a sheet-type structure, wherein the molding part comprises:
- a third roller member comprising:
- a third body portion having a cylindrical shape having a constant outer diameter along its longitudinal axis and configured to be rotatable by a third rotational shaft arranged along a width direction of the sheet-type fiber composite material, and
- a pair of third protruding portions, each of the third protruding portions having a cylindrical shape having a constant outer diameter along their longitudinal axes, located at either lateral side of the third body portion and each having an outer diameter greater than that of the third body portion;
- and
- a molding guide located on an upper side of the third roller member in parallel therewith, the molding guide comprising:
- a first wall body located at an outer lateral side of one of the third protruding portions and having a predetermined height,
- a second wall body located at an outer lateral side of the other third protruding portion and having a height same as that of the first wall body, and
- an upper plate extending over the first wall body and second wall body and connecting and fixing the first wall body and the second wall body to each other;
- wherein the molding part is configured to press the fiber composite material in the direction of its thickness between the third roller member and the molding guide;
- and
- a compressing part located downstream of the molding part, having a shape corresponding to a shape of an upper surface of the sheet-type structure, and configured to compress the upper surface of the sheet-type structure fed from the molding part, thereby disposing the sheet-type structure on a substrate in a state of maintaining the shape of the sheet-type structure;
- wherein the compressing part moves from one end to the other end of the substrate.
