[Statement]
[Name of Invention]
Composite Rod and Its Manufacturing Method
[Technical Field]
This invention relates to a fixing composite rod, and it introduces a composite rod and its
manufacturing method formed through a winding method to make it lightweight and capable of
withstanding a high tensile load.
[Background Art]
In general, composite rods are commonly used to connect devices for the purpose of
preventing a specific inclination or collapse of relevant instruments.
Commonly used metal rods with high tensile strength cause difficulties in operation due
to their excessive weight, while hollow composite rods cause issues of lowered tensile strength due
to their lightweight nature.
Therefore, there is a high demand for research and development concerning lightweight
composite rods with excellent tensile strength.
[Detailed Description of the Invention]
[Technical Challenges]
The purpose of this invention aims to create a composite rod made of composite materials
that use continuous fibers with higher tensile strength and lower specific gravity than metals by the
filament winding method to reduce the excessive weight of the composite rod and provide relevant
manufacturing methods for them.
[Technical Solution]

composite rod shall include a primary thimble unit that provides a space for continuous fibers to
be wound, a secondary thimble unit that provides a space for continuous fibers to be wound, and the continuous fibers that are wound through the primary and secondary thimble units and include an overlapping part that mediates the primary and secondary thimble units to be interdependent.
The overlapping part shall include the primary flexure portion that passes through the outer
circumferential surface of the primary thimble unit, the secondary flexure portion that passes
through the outer circumferential surface of the secondary thimble unit, and overlapping fiber units
that are deployed in the space between the primary and the secondary thimble units. The length
of the composite rod may be determined according to the separation distance of the primary and
the secondary thimble unit, which are subordinated by the overlapping unit.
The primary thimble unit of the composite rod, in accordance with an embodiment of this
invention, shall consist of a primary body unit that allows the continuous fiber to be wound while
being subordinated and a primary continuous fiber unit that overlaps and winds to the primary
body unit. The secondary thimble unit shall consist of a secondary body unit that allows the
continuous fiber to be wound while being subordinated and a secondary continuous fiber unit that
overlaps and winds to the secondary body unit. And the sum of the thickness of the primary
continuous fiber unit wound around the primary body unit and the thickness of the primary flexure
portion and the sum of the thickness of the secondary continuous fiber unit wound on the
secondary body unit and the thickness of the secondary flexure portion may have the same
thickness as the overlapping fiber unit.
In accordance with an embodiment of this invention, the primary body unit of the
composite rod consists of a primary base unit with at least a part of an outer circumferential surface
formed to be in a round shape, and a primary winding groove formed by invagination exhibiting
along an outer surface of the primary base unit. The primary winding groove may limit the deviation
of the wound continuous fiber from the primary base unit. And the secondary body unit consists
of a secondary base unit with at least a part of an outer circumferential surface formed to be in a
round shape, and a secondary winding groove formed by invagination exhibiting along an outer surface of the secondary base unit. The secondary winding groove may limit the deviation of the wound continuous fiber from the secondary base unit.
In accordance with an embodiment of this invention, the primary body unit of the
composite rod consists of a primary support unit, with the size of the longitudinal area gradually
decreasing as the distance from the primary base unit increases while being extended from the
primary base unit. In addition, the secondary body unit shall also consist of a secondary support
unit, with the size of the longitudinal area gradually decreasing as the distance from the secondary
base unit increases while being extended from the secondary base unit. The primary and secondary
support units may be capable of supporting the overlapping fiber unit while being placed within
the interior of the overlapping fiber unit.
The composite rod, in accordance with an embodiment of this invention, further includes
a reinforced fiber unit that allows for the shape of the overlapping fiber unit to be maintained while
being wound around the overlapping fiber unit, and the reinforced fiber unit may be wound in
response to the longitudinal property of the overlapping fiber unit at various angles.
As for the composite rod, in accordance with an embodiment of this invention, it consists
of multiple winding fiber units passing through the primary and the secondary thimble units, and
each of the winding fiber units constituting the multiple winding fiber units may hold the same
tensile force.
As for each of the winding fiber units constituting the multiple winding fiber units of the
composite rod in accordance with an embodiment of this invention, the number of rotations of the
overlapping fiber unit can be increased to be wound in regions where the amount of deflection is
to be increased or it can be wound using materials with a relatively large amount of deflection.
As for the manufacturing method of fixing composite rods in accordance with an
embodiment of this invention, it shall include Stage 1 that prepares a primary thimble unit where
a space in which continuous fibers are wound is formed, followed by Stage 2 that prepares a secondary thimble unit where a space in which continuous fibers are wound is formed, Stage 3 that winds the overlapping units consisting of multiple continuous fibers via the primary and the secondary thimble units to allow for the primary thimble unit and the secondary thimble unit to be interdependent, and Stage 4 that winds a reinforced fiber unit consisting of multiple continuous units into the overlapping unit to allow for the shape of the overlapping unit to be maintained. As a result, the length of the composite rod may be determined according to the separation distance of the primary and the secondary thimble unit, which are subordinated by the overlapping unit.

Drawing 1 is a schematic perspective view showing a composite rod in accordance with an
embodiment of this invention, and Drawing 2 is a schematic diagram explaining the relevant
changes in response to the length of the composite rod in accordance with an embodiment of this
invention.
Drawing 3 is a schematic diagram explaining the reinforced fiber unit of the composite rod in accordance with an embodiment of this invention, and Drawing 4 is a schematic diagram explaining the composite rod in accordance with an embodiment of this invention.
In reference to Drawings 1 or 4, the composite rod (1), in accordance with an embodiment
of this invention, may be a fixing device.
The composite rod (1) may include a primary thimble unit (10), a secondary thimble unit
(20), an overlapping unit (30), and a reinforced fiber unit (40).
The primary thimble unit (10) may provide space for continuous fibers to be wound while
being subordinated.
Specifically, the primary thimble unit (10) may include a primary body unit (11) that allows
for the continuous fibers to be wound while being subordinated to them.
The primary body unit (11) shall include a primary base unit (111) with at least a part of
an outer circumferential surface formed to be in a round shape and a primary winding groove (113)
formed by invagination exhibiting along an outer surface of the primary base unit (111).
The primary winding groove (113) can limit the deviation of the wound continuous fiber
from the primary base unit (111). The primary winding groove (113) may be formed by projections
protruding from both ends of the primary base unit (111), and it can induce winding at regular
intervals as fine protruding lines (not shown in drawings) protruding at regular intervals along the
outer circumferential surface are created, causing the wound continuous fiber to not move along
the outer circumferential surface as a result.
The secondary thimble unit (20) may provide space for continuous fibers to be wound
while being subordinated.
Specifically, the secondary thimble unit (20) may include a secondary body unit (21) that
allows for the continuous fibers to be wound while being subordinated to them.
The secondary body unit (21) shall include a secondary base unit (211) with at least a part of an outer circumferential surface formed to be in a round shape and a secondary winding groove
(213) formed by invagination exhibiting along an outer surface of the secondary base unit (211).
The secondary winding groove (213) can limit the deviation of the wound continuous fiber
from the primary base unit (111).
The secondary winding groove (213) can limit the deviation of the wound continuous fiber
from the secondary base unit (211). The secondary winding groove (213) may be formed by
projections protruding from both ends of the secondary base unit (211), and it can induce winding
at regular intervals as fine protruding lines (not shown in drawings) protruding at regular intervals
along the outer circumferential surface are created, causing the wound continuous fiber to not
move along the outer circumferential surface as a result.
As for the primary thimble unit (10) and the secondary thimble unit (20), the fastening
method of the composite rod (1), the diameter of the composite rod (1) (amount of fiber in the
wound continuous fiber), and the corresponding hardness may be determined according to the
created shape, and the user may make appropriate changes to create the required environments
where composite rod (1) is used and obtain the necessary limit tensile force.
As for the overlapping unit (30), it shall consist of multiple wound continuous fibers that
pass through the primary thimble unit (10) and the secondary thimble unit (20), and it can be
mediated to allow for the primary and the secondary thimble units to be interdependent.
Specifically, the overlapping unit (30) shall include an overlapping fiber unit (35) in the
secondary flexure portion (32) and the overlapping part that separates space between the primary
(10) and the secondary thimble unit (20) via the outer circumferential surface of the primary thimble
unit (10) while passing through the outer circumferential surface of the primary flexure portion (31)
and the secondary thimble unit (20).
The overlapping fiber unit (35) may be in a rotating state between the primary flexure
portion (31) and the secondary flexure portion (32). Although the overlapping fiber unit (35) is shown as a single rotation in the drawing, it may have been rotated multiple times. The number of rotations of the overlapping fiber unit (35) may vary depending on the relevant material and thickness of the continuous fiber.
The length of the composite rod (1) can be determined according to the separation
distance of the primary (10) and the secondary thimble unit (20), which are subordinated by the
overlapping unit (30).
Specifically, the length of the composite rod (1) in this invention can vary depending on
the length of the overlapping fiber unit (35), that is, the separation distance of the primary (10) and
the secondary thimble unit (20), and the user may make appropriate changes to create the required
environments where composite rod (1) is used and obtain the necessary limit tensile force.
Meanwhile, the primary thimble unit (10) shall further consist of primary continuous fiber
units (13) that overlap and wind around the primary body unit (11), and the secondary thimble unit
(20) shall further consist of secondary continuous fiber units (23) that overlap and wind around the
secondary body unit (21).
The sum of the thickness (dl, see Drawing 4) of the primary continuous fiber unit (13)
wound around the primary body unit (11) and the thickness (d2, see Drawing 4) of the primary
flexure portion (31), and the sum of the thickness (d1) of the secondary continuous fiber unit (23)
wound on the secondary body unit (21) and the thickness (d2) of the secondary flexure portion (32)
with the thickness (2*d2) of the overlapping fiber unit (35) may be identical. The thickness (d1) of
the primary continuous fiber unit (13) and the thickness (d2) of the primary flexure portion (31) are
identical.
This is to prevent destruction by a relatively weak part when the tensile of the composite
rod (1) is increased by allowing for the amount of external force endured by the continuous fibers
wound around the primary thimble unit (10), the size of the external force endured by the
continuous fibers wound around the secondary thimble unit (20), and the size of the external force endured by the overlapping fiber unit (35) to be identical.
Specifically, if the primary continuous fiber unit (13) and the secondary continuous fiber
unit (23) are absent, the resistance to the external force of the primary flexure portion (31) and the
secondary flexure portion (32) will be only half of that of the overlapping fiber unit (35) because
the thickness of the primary flexure portion (31) wound around the primary body unit (11) and the
thickness of the secondary flexure portion (32) wound around the secondary body unit (21) will be
half the thickness of the overlapping fiber unit (35). As a result, the performance of the composite
rod (1) may not be realized at its greatest due to partial destruction occurring in the primary flexure
portion (31) and the secondary flexure portion (32) before reaching the maximum load of the
composite rod (1).
In order to prevent such a case of poor performance, this invention is capable of forming
the primary flexure portion (31), the secondary flexure portion (32), and the overlapping fiber unit
(35) by winding continuous fibers on the outer surface while allowing for the primary continuous
fiber unit (13) to be wound around the primary body unit (11) and the secondary continuous fiber
unit (23) to be wound around the secondary body unit (21).
Meanwhile, the reinforced fiber unit (40) may be wound around the overlapping fiber unit
(35), which would allow for the shape of the overlapping fiber unit (35) to be maintained.
The reinforced fiber unit (40) may be wound in response to the longitudinal property of
the overlapping fiber unit (35) at various angles in the circumferential direction. Specifically, the
reinforced fiber unit (40) is wound along the outer circumferential surface of the overlapping fiber
unit (35), and the corresponding winding angle may be wound in response to the longitudinal
property of the overlapping fiber unit (35) at various angles.
In addition, the reinforced fiber part (40) can be formed to have the same thickness
between the primary flexure portion (31), the secondary flexure portion (32), and the overlapping
fiber unit (35) as a result of winding around the primary (31) and the secondary flexure (32) portions.
The primary continuous fiber unit (13) may be wound in a twisted form around the primary
body unit (11) for structural integration between the multiple wound continuous fibers. In addition,
the secondary continuous fiber unit (23) may be wound in a twisted form around the secondary
body unit (21) for structural integration between the multiple wound continuous fibers.
Here, in principle, the primary continuous fiber units (13) or the secondary continuous fiber
units (23) shall be kept wound using the same continuous fiber, but they may be formed using
different materials for each layer. If it is formed using different materials for each layer, the amount
of twists can be adjusted in consideration of the rigidity of each fiber. Preferably, fiber with relatively
high rigidity increases the amount of twists, and fiber with relatively low rigidity can decrease the
amount of twists.
Drawing 5 is a schematic diagram explaining the composite rod in accordance with a
different embodiment of this invention.
In reference to Drawing 5, the primary thimble unit (10a) of the composite rod (1) in
accordance with a different embodiment of this invention, the primary body unit may include the
primary support unit (115).
As for the primary support unit (115), it may be formed to allow for the size of the
longitudinal area to gradually decrease as the distance from the primary base unit (111a) increases
while being extended from the primary base unit (111a).
Also, the secondary body unit of the secondary thimble unit (20a) may include the
secondary support unit (215).
As for the secondary support unit (215), it may be formed to allow for the size of the
longitudinal area to gradually decrease as the distance from the secondary base unit (211a)
increases while being extended from the secondary base unit (211a).
The primary support unit (115) and the secondary support unit (215) may provide support
for the overlapping fiber unit (35) while being placed in the interior of the overlapping fiber unit
(35).
This will maximize the efficiency of internal reinforcement by expanding the regions of
internal reinforcement corresponding to the overlapping fiber unit (35).
Drawing 6 is a schematic diagram explaining the relevant structures of the overlapping
units of the composite rod in accordance with an embodiment of this invention.
In reference to Drawing 6, the overlapping unit (30) of the composite rod (1), in accordance
with an embodiment of this invention, consists of multiple winding fiber units (30a, 30b, and 30c)
that pass through the primary thimble unit (10) and the secondary thimble unit (20), and each of
the winding fiber units (30a, 30b, and 30c) constituting the multiple winding fiber units (30a, 30b,
and 30c) are capable of holding the same tensile force.
As for each of the winding fiber units (30a, 30b, and 30c) constituting the multiple winding
fiber units (30a, 30b, and 30c), the number of rotations of the overlapping fiber unit (35) can be
increased in regions where the amount of deflection is to be increased or it can be wound using
materials with a relatively large amount of deflection.
Specifically, the multiple winding fiber units (30a, 30b, and 30c) require longer winding
lengths depending on the thickness of the accumulated continuous fiber as the distance from the
primary thimble unit (10) and the secondary thimble unit (20) increases. As a result, the size of the
tensile force exhibited by each of the winding fiber units (30a, 30b, and 30c) may vary depending
on such a difference in length.
Hence, in this invention, first, the difference in length can be overcome to allow for the winding fiber units (30a, 30b, and 30c) of the same length to be applied by increasing the number of rotations, in particular, for the winding fiber units (30a, 30b, and 30c) located on the interior part of the unit. Second, although the winding fiber units (30a, 30b, and 30c) of different lengths may be used, decreased tensile force caused by a difference in length may be compensated for, in particular, for the winding fiber units (30a, 30b, and 30c) located on the interior part of the unit.
Here, in principle, the multiple winding fiber units (30a, 30b, and 30c) shall be kept wound
using the same continuous fiber, but they may be formed using different materials for each layer.
If it is formed using different materials for each layer, the amount of rotation can be adjusted in
consideration of the rigidity of each fiber. Preferably, fiber with relatively high rigidity increases the
amount of rotation, and fiber with relatively low rigidity can decrease the amount of rotation.
Meanwhile, the manufacturing method of the composite rod (1) in accordance with an
embodiment of this invention may include all components of Stages 1 to 4.
Stage 1 may include the preparation of the primary thimble unit (10) in which a space for
continuous fibers to be wound is formed.
Specifically, Stage 1 may include Stage 1-1 which prepares the primary body unit (11)
which provides a space for continuous fibers to be wound while being subordinated, and Stage 1
2, with multiple continuous fibers wound on the primary body unit (11).
Stage 2 may include preparation of the secondary thimble unit (20) in which a space for
continuous fibers to be wound is formed.
Stage 2 may include Stage 2-1 which prepares the secondary body unit (21), which provides
a space for continuous fibers to be wound while being subordinated, and Stage 2-2, with multiple
continuous fibers wound on the secondary body unit (21).
Stage 3 shall wind the overlapping units (30) consisting of multiple continuous fibers via
the primary (10) and the secondary thimble units (20) to allow for the primary thimble unit (10) and the secondary thimble unit (20) to be interdependent.
Stage 4 winds a reinforced fiber unit (40) consisting of multiple continuous units into the
overlapping unit (30) to allow for the shape of the overlapping unit (30) to be maintained.
The length of the composite rod (1) can be determined according to the separation
distance of the primary (10) and the secondary thimble unit (20), which are subordinated by the
overlapping unit (30).
The configuration and characteristics of this invention have been described above based
on embodiments of this invention, however, the ideas concerning this invention shall not be limited
to the presented examples, and it evidently states that the person skilled in the relevant field of
technology is capable of making changes and modifications within the scope of the relevant idea.
