A multifilament wet‐pull‐out method for estimation of physicochemical interaction between the fiber and the matrix in composite materials reinforced with high‐strength high‐modulus polyethylene fiber has been proposed. Controlled parameters are fiber capillary rise h and pull‐out force F . The method allows one to estimate the wettability and multifilament fiber impregnation with the liquid matrix and measure fiber capillary rise and the joint strength after curing process finished. The multifilament wet‐pull‐out method considers a total interaction between the matrix and filaments in a complex fiber or yarn. It is the advantage of this method in comparison with the tests of individual monofilament. The method makes it possible to model the real operating conditions of CM.
