1.1 This part of GB/T 1040 specifies the general principles for determining the tensile properties of plastics and composite materials under specified conditions, and specifies several different shapes of test specimens for different types of materials. These materials are specified in other parts of this standard. part is detailed. 1.2 This method is used to study the tensile properties of samples and determine the tensile strength, tensile modulus and other tensile stress/strain relationships under specified conditions. 1.3 This method is applicable to the following materials: — rigid and semi-rigid thermoplastic molding and extrusion materials, including filled and reinforced compounds in addition to unfilled types, rigid and semi-rigid thermoplastic sheets and films ; - rigid and semi-rigid thermosetting molding materials, including filled and reinforced composites, rigid and semi-rigid thermosetting sheet materials, including laminates; - fiber-reinforced thermosetting materials mixed with unidirectional or non-directional reinforcement and thermoplastic composites, such as mats, fabrics, rovings, chopped strands, hybrid fiber reinforcements, rovings and milled fibers, etc.; sheets made of pre-impregnated materials (prepregs); - Thermotropic liquid crystal polymers. This method is generally not applicable to rigid foams or sandwich structures containing microcellular materials. 1.4 Specimens used in this method may be molded to selected dimensions, or may be machined by cutting, punching, etc., from finished or semi-finished moldings, laminates, films, extruded or cast sheets, etc. become. In some cases, multi-purpose test pieces can be used (see IS03167:1993 "Plastics - Preparation and use of multi-purpose test pieces"). 1.5 This method specifies preferred dimensions for specimens. The results of tests performed on specimens of different dimensions or prepared under different conditions are not comparable. Other factors, such as test speed and conditioning of the specimen, can also affect test results. Therefore, when data comparisons are required, these influencing factors must be strictly controlled and documented.
