Tensile Test Method for Basalt Roving

In the construction industry there is no method for tensile testing of materials of basalt complex filaments of small diameters and roving. The existing methods of testing fibers and roving presented in regulatory documents are intended for textile materials and materials based on fiberglass. The studies cited in the article were aimed at studying the strength properties of roving materials and a multifilament yarn based on basalt fibers, as well as working out methods for testing them. The article presents studies of the strength characteristics of roving and complex yarn based on basalt fiber, on which testing of basalt material samples was tested. The strength characteristics of various forms of basalt materials for various adhesive processing were obtained. The applied experimental test procedure was appreciated positively.
