Abstract

The glass-fiber-yarn joined body 1 is provided with glass fiber yarns 2, 3, and a connection 5 in which a resin yarn 4 is wound around ends of both of the glass fiber yarns 2, 3, the ends being superimposed with each other. The connection 5 has a width W1 of 20 to 40 mm. When a connection diameter R as a total of diameters of the respective glass fiber yarns 2, 3 and the thickness of the resin yarn 4 wound around the connection 5 is 500 to 5000 μm and a mass of each of the glass fiber yarns 2, 3 is 200 to 6000 tex, a value of a ratio of mass of each of the glass fiber yarns 2, 3 relative to the connection diameter R is in the range of 0.32 to 2.00.

First claim

The invention claimed is:

1. A glass-fiber-yarn joined body, comprising:
a first glass fiber yarn;
a second glass fiber yarn; and
a connection in which a resin yarn is wound around ends of both of the glass fiber yarns, the ends being superimposed with each other,

wherein
the connection has a width in a range from 20 to 40 mm, and
a connection diameter as a total of diameters of the respective glass fiber yarns and a thickness of the resin yarn wound around the connection is in a range of 500 to 5000 μm and a mass of each of the glass fiber yarns is in a range of 200 to 6000 tex, and a value of a ratio of mass of the glass fiber yarn relative to the connection diameter (mass of glass fiber yarn/connection diameter) is in a range of 0.32 to 2.00.

2. The glass-fiber-yarn joined body according to claim 1 , wherein a width of a wound part where the resin yarn is wound is in a range of 60 to 110% of a width of the connection.

3. The glass-fiber-yarn joined body according to claim 1 , wherein the value of the ratio of mass of the glass fiber yarn relative to the connection diameter in the glass-fiber-yarn joined body of claim 1 is in a range of 0.64 to 1.55.

4. A glass-fiber-reinforced resin molded product, comprising:
a glass-fiber-yarn joined body that includes
a first glass fiber yarn,
a second glass fiber yarn, and
a connection in which a resin yarn is wound around ends of both of the glass fiber yarns, the ends being superimposed with each other,

and in which
the connection has a width in a range from 20 to 40 mm, and
a connection diameter as a total of diameters of the respective glass fiber yarns and a thickness of the resin yarn wound around the connection is in a range of 500 to 5000 μm and a mass of each of the glass fiber yarns is in a range of 200 to 6000 tex, and a value of a ratio of mass of the glass fiber yarn relative to the connection diameter (mass of glass fiber yarn/connection diameter) is in a range of 0.32 to 2.00.

5. The glass-fiber-reinforced resin molded product according to claim 4 , wherein a width of a wound part where the resin yarn is wound is in a range of 60 to 110% of a width of the connection.

6. The glass-fiber-reinforced resin molded product according to claim 4 , wherein the value of the ratio of mass of the glass fiber yarn relative to the connection diameter is in a range of 0.64 to 1.55.
