Embodiment Construction

[0017] like figure 1 As shown, the present invention includes: an X-axis tension-compression unit 1, a Y-axis tension-compression unit 2, a vertical burst unit 4 and a digital speckle (DSCM) test unit 3; wherein, the X-axis tension-compression unit 1 is used for the material to be tested performed in the X-axis (at figure 1 The tension and compression in the left and right directions); the Y axis tension and compression unit 2 is used for figure 1 The vertical bursting unit 4 is used for the material to be tested to be stretched along the X-axis and the Y-axis when the material to be tested is stretched along the plane perpendicular to the X-axis and the Y-axis. The abutment force in the direction of the X-axis and the Y-axis at an angle of 90°; the digital speckle (DSCM) test unit 3 is used to measure the deformation process and failure trend of the material to be tested under force.

[0018] The above-mentioned vertical bursting unit 4 includes: a vertical bursting head 43...

Abstract

The invention provides a three-dimensional mechanical property tester for fabric and textile structural composite materials. The tester comprises an X-axis tension and compression unit, a Y-axis tension and compression unit, a vertical bursting unit and a digital speckle test unit. The X-axis tension and compression unit is used for tension or compression test of to-be-tested materials in an X-axis direction, the Y-axis tension and compression unit is used for tension or compression test of to-be-materials in a Y-axis direction, the vertical bursting unit is used for exerting abutting force along a direction which forms an included angle of 90 degrees with a plane of the X-axis and the Y-axis when performing X-axis tensioning and / or Y-axis tensioning on the to-be-tested materials, and the digital speckle test unit is used for measuring deformation of the to-be-tested materials when damaged by force. By performing one-way tension and compression and two-way tension and compression on the to-be-tested materials and exerting the vertical abutting force to test vertical bursting property of the to-be-tested materials when performing tension test, accurate analysis to three-dimensional multidirectional stressed damage property of the to-be-tested materials is realized.

Description

technical field [0001] The invention relates to an analysis device used for the detection and evaluation of the three-dimensional mechanical properties of fiber fabrics and textile structure composite materials. Background technique [0002] Fiber textile structure composite material is an advanced composite material made of natural (chemical) fiber, yarn or fabric and other textiles as a reinforced structure. The advantages of high specific modulus and small anisotropy are unmatched by other reinforcing materials. Composite materials made of fiber textile materials are widely used in interior decoration, aerospace, fire equipment and automotive interior decoration and other fields. [0003] Because the fiber fabric has the characteristics of warp and weft interwoven structure, the current research on the tensile properties of fabrics in the textile industry mainly focuses on the uniaxial stretching and biaxial stretching of the fabrics, which is very important to accuratel...
