Carbon/carbon composite shear test

In the field of nuclear energy, carbon materials are important moderator materials for nuclear reactors; in the photovoltaic industry, graphite and carbon/carbon composite materials can be used for thermal insulation parts, high-temperature fasteners, heating elements, structural supports and other consumable materials; in the field of energy conservation and environmental protection, carbon materials can be used as heating elements and thermal insulation components of various vacuum high-temperature industrial furnaces, which can improve their energy-saving effect; they can also be used as electrode plates for clean energy fuel cells; in the field of transportation, they can be used as high-performance friction materials for high-end cars or heavy-duty vehicles.
Carbon/carbon composite material shear test can use the punching shear method to determine the shear strength of carbon/carbon composite material. Zhongke Testing Reliability Experiment Center has the reliability testing capabilities for various carbon/carbon composite materials and provides professional shear testing services for carbon/carbon composite materials.

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.

applies a uniaxial compressive load on a ring-shaped specimen through a circular clamp at a constant rate. The load direction is perpendicular to the specimen plane, forming shear stress in the thickness direction of the specimen until the specimen is destroyed, thereby measuring the shear strength of the specimen.
