Fabric Tear Performance Tester - (Impact Pendulum Tear Strength Determination), Electronic Fabric Tear Tester (Impact Pendulum Tear Strength Determination)

The fabric tearing performance tester (impact pendulum method) is a professional equipment that quantitatively measures the tear resistance of fabrics by simulating the scenario of external tearing during actual use. The core principle is based on the law of conservation of energy, which tears the specimen with the kinetic energy released by the falling pendulum, measures the energy consumed during the tearing process, and finally converts it into tearing strength. This device is a key tool for evaluating material durability in industries such as textiles, packaging, and healthcare.

1、 Working principle

Energy accumulation stage

The pendulum is lifted to its initial height, at which point it has potential energy.

The sample is fixed in the upper and lower fixtures and pre cut in the middle to simulate the actual tear starting point.

Energy Conversion and Tearing Stage

Release the pendulum, and during its free fall, potential energy is converted into kinetic energy.

When the pendulum impacts the specimen, the kinetic energy is used to overcome the bonding force between the fabric fibers, causing the incision to expand in the predetermined direction.

After the tearing is completed, the pendulum continues to swing to the remaining height, and the remaining potential energy represents the energy that has not been consumed.

Data calculation and output

Calculate the energy consumed by tearing the specimen by measuring the difference between the initial height and the remaining height of the pendulum.

Convert to tear strength based on the mass of the pendulum, gravitational acceleration, and tear length.

The results are directly displayed on the digital screen and support unit switching.
