Abstract

An evaluating device of a flexural property includes a holder, a body disposed on the holder and capable of being moved along with a length of direction of the holder, a clamp coupled to the body to be rotated on the body and fixing a first side of the specimen to be evaluated, and a pressing part disposed over the clamp and pressing a second side of the specimen opposite to the first side and disposed upper than the first side of the specimen to bend the specimen, and an evaluation method of a flexural property of the bent specimen using the same.

Claims

1. A device for evaluating flexural property comprising:

a holder,

a body disposed on the holder and capable of being moved along with a length direction of the holder,

a clamp coupled to the body and capable of being rotated on the body and fixing a first side of a specimen to be evaluated,

a pressing part which is disposed on the clamp, contacts and directly presses a second side of the specimen opposite to the first side and is disposed upper than the first side of the specimen to bend the specimen,

a wire connected with each of the body and the pressing part, and

a pulley wound with the wire.

2. The device of claim 1, further comprising:

a rotation axis penetrating the body and the clamp and inserted through the body and the clamp; and

a manipulating dial coupled to a terminal end of the rotation axis.

3. The device of claim 2, wherein an elongation direction of the rotation axis is different from the length direction of the holder.

4. The device of claim 1, wherein an angle between the clamp and the body is about 0 degree to about 180 degrees.

5. The device of claim 1, wherein the body is disposed to be slid along with the length direction of the holder.

6. The device of claim 5, wherein a guide groove is defined in an upper surface of the holder along with the length direction of the holder, and

a movement member is disposed on a lower surface of the body to be accommodated in the guide groove.
