The paper shows the results of an experimental-theoretical study aimed at investigating the adhesive properties of the filament-matrix interface. The characteristic fields of strain when pulling a single filament from the matrix are shown. The filament length at which the load reaches a "plateau" is experimentally determined. According to this effect, it is possible to estimate the value of the critical filament length for a certain material, at which a local fiber break in the matrix does not affect the strength of the entire structure.
