Product Description

PCY-F Thermal dilatometer expansion coefficient meter coating residual stress comprehensive testing machcine
1.Product introduction
Patent of Professor Bao from China Building Materials Research Institute: This instrument can test the expansion coefficient and residual stress of the matrix, coating and composite sample of composite materials.
1. Prepare sample A (matrix, without coating) and sample B (with coating, composite sample)
Use precision measuring tools, such as optical microscope, to measure the cross-sectional area Ac of the coating and the cross-sectional area As of the matrix on sample B respectively. (Requires input before experiment). Under the same experimental environment, obtain the thermal expansion coefficient C1 of sample A (matrix) and the thermal expansion coefficient C2 of sample B (composite) at the same time; calculate the thermal expansion coefficient of the coating using the thermal expansion coefficient results of sample A and sample B.
2. Test two expansion coefficients and calculate the expansion coefficient of the coating, a total of three expansion coefficients:

The thermal expansion coefficient C1 of sample A (matrix); the thermal expansion coefficient C2 of sample B (composite); the thermal expansion coefficient C of the coating of the target object
3. The software makes a judgment:
If C1>C2, the residual stress is compressive stress, otherwise it is tensile stress, and the residual stress value of the coating is calculated to MPa.
