Compression testing device for testing materials automatically

摘要

A compression testing assembly for compression testing of a test material includes a testing stage with a first surface and a second surface. The test material is disposed between the first and second surfaces. The assembly also includes a thickness detector that automatically detects a thickness of the test material. Moreover, the assembly includes an actuator that moves at least one of the first and second surfaces toward the other of the first and second surfaces to compress the test material to a predetermined percentage of the detected thickness of the test material. Additionally, the assembly includes a load detector that detects a compression load of the test material and that detects a change in the compression load over time.

1. A compression testing assembly for compression testing of a test material, the compression testing device comprising:
a testing stage including a first surface and a second surface, the test material being disposed between the first and second surfaces; a thickness detector that automatically detects a thickness of the test material; an actuator that moves at least one of the first and second surfaces toward the other of the first and second surfaces; a controller operable to control the actuator according to the thickness detected by the thickness detector, the controller operable to control the actuator to compress the test material to a predetermined percentage of the thickness of the test material as detected by the thickness detector; a load detector that detects a compression load of the test material and that detects a change in the compression load over time; and a position detector that detects a position of the first surface relative to the second surface, wherein the thickness detector communicates with both the position detector and the load detector by detecting a distance between the first and second surfaces when the compression load initially increases as the first and second surfaces are relatively moving toward each other to detect the thickness of the test material.
