Carbon Fiber Composite Core Torsion Testing Machine

The Carbon Fiber Composite Core Rod Torsion Testing Machine is designed to evaluate the ability of metal and non-metal wires or rods to withstand plastic deformation during unidirectional or bidirectional torsion. It can also reveal surface and internal defects in the test specimen.

Main Functions and Applications

Unidirectional Torsion:

The specimen is uniformly rotated around its own axis in one direction until the specified number of turns is reached or the specimen fractures.

Bidirectional Torsion:

The specimen is uniformly rotated around its own axis in one direction for a specified number of turns and then rotated in the opposite direction for the same number of turns or until fracture occurs.

The wire torsion testing machine is suitable for determining the ability of metal wires with a diameter or characteristic dimension of 0.1–14 mm to withstand plastic deformation under unidirectional or bidirectional torsion, while also identifying surface and internal defects.

Applicable Materials

The machine can be used for a wide range of metal and non-metal wire materials, including:

Steel Wires: Fine steel wires and other steel wire materials

Copper Wires: Copper wires, copper alloys, etc.

Aluminum Wires: Aluminum wires, aluminum alloys, etc.

Other Materials: Fiberglass-reinforced materials, ultra-fine fibers, alloy steel and other applicable materials

It can also be configured for testing carbon fiber composite core rods according to specific specimen dimensions and test requirements.
