Abstract
A holding clamp for use in a testing apparatus for determining tensile and sheer strength characteristics of a reinforcement sheet. The holding clamp defines a channel having at least two adjacent bearing surfaces and an opening to an exterior surface. An elongate clamping bar conforming in cross-sectional shape at least relative to the pair of adjacent bearing surfaces is received within the channel with an end portion of the reinforcement sheet overwrapping the clamping bar and a portion of the reinforcement sheet extends outwardly through the opening for securing in the testing apparatus. A loading mechanism moves the clamp to load the reinforcement sheet, whereby the tensile or sheer strength characteristics can be determined. A method of clamping an end of a reinforcement sheet to be tested for tensile or sheer strength characteristics is disclosed for a testing apparatus.
