Carbon/carbon composite compression test

Carbon/carbon composite compression test can measure the compressive strength, compressive elastic modulus, and compressive stress-strain curve of three-dimensional punctured carbon/carbon composites and quasi-three-dimensional needle-punched carbon/carbon composites at room temperature.
Zhongke Testing Reliability Experiment Center has reliability testing capabilities for various carbon/carbon composite materials and provides professional compression testing services for carbon/carbon composite materials. The purpose of the

According to the type or weaving method of fibers, carbon/carbon composite materials can be divided into short fiber reinforced carbon/carbon composite materials, unidirectional continuous fiber reinforced carbon/carbon composite materials, laminated fabric (carbon cloth overlapping or raw silk felting) reinforced carbon/carbon composite materials, and three-dimensional braid reinforced carbon/carbon composite materials.

1. When measuring the compressive strength, continuously load the sample at a loading rate of 1.0 mm/min until the sample is damaged, and record the maximum damage load. After the specimen is damaged, visually inspect the fracture site of the specimen, and record the specimen's failure mode.
2. When measuring the compressive elastic modulus, continuously load the sample at a loading rate of 0.5 mm/min, continuously measure and record the load-strain data, and stop the test until the strain is 0.20%.
