Abstract
The invention discloses a composite material NOL loop test spline cutting device which comprises a base, an electric cutting machine, a linear guiderail, a guiderail sliding block, a worktable and a locking device, wherein the electric cutting machine and the linear guiderail are arranged on the base; the guiderail sliding block is matched with the linear guiderail and capable of reciprocating along the linear guiderail; the worktable and the locking device are arranged on the guiderail sliding block. The composite material NOL loop test spline cutting device is simple in structure and convenient to operate; according to the composite material NOL loop test spline cutting device, the cutting time is only 1 / 10 of the original cutting time and even less, the cut spline incisions are smooth, burr-free and crack-free, the tested spline is small in size deviation and high in precision and the potential safety hazards in the cutting process are avoided.
Description
technical field [0001] The invention relates to a composite material test sample cutting device, in particular to a composite material NOL ring interlayer shear performance test sample cutting device. Background technique [0002] The interlaminar shear strength of composite materials is a performance index to measure the interlaminar characteristics of composite materials, which reflects the strength of the interface between the composite material matrix and the reinforcement, and is an important index for evaluating the performance of composite materials. The short beam shear method is the most commonly used test method for measuring the apparent interlaminar shear strength of composite materials. Commonly used standards include ASTM2344 and GB / T 1458-2008. The ring specimens used in the standards are called composite material NOL rings. , after cutting the NOL ring into a test strip with a standard arc length, the apparent interlaminar shear strength of the composite mate...
