SAMPLE FOR THE REINFORCING THREADS AND POLYMER BINDER ADHESION CONNECTION STRENGTH DETERMINING AND ITS MANUFACTURING METHOD Russian patent published in 2019 - IPC G01N1/28 G01N19/04 B32B5/08 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to the field of polymer composite materials and composite power structures production and can be used for the reinforcing threads and polymer binders different types bonding adhesion strength determine. Disclosed is a sample for the reinforcing threads and polymer binder adhesive bonding strength determining, made in form of connected threads, according to the invention threads form the T-shaped element having the fixed connection area, which is enclosed into the rectangular two-layer plate from liner material with longitudinal slot to its center, in which thread together with gluing is arranged with minimum clearance, and the other thread sections to slot are fixed between the liner material layers with elastic glue, wherein the liner material plate thickness exceeds the gluing thickness. In the method of a sample making for the reinforcing threads and polymer binder adhesive bonding strength determining, including the threads impregnation with binder and their connection, according to the invention the threads winding is carried out at angle of 90° on mandrel with liner material, having positive curvature with the threads increased tension, or on the flat mandrel with the contact pressure subsequent application, and the liner material outer layer gluing.

EFFECT: technical result is enabling the samples manufacturing simplicity, high efficiency, their testing results stability.
