This standard replaces GB/T 3355-2005 "fiber reinforced plastics aspect shear test method." This standard and GB/T 3355-2005 Compared to the main changes are as follows. --- Standard name from "vertical and horizontal shear test method for plastic fiber reinforced" with a "polymer matrix composites aspect shear test side law"; --- The scope of the original "Determination of unidirectional fiber or fabric-reinforced plastic flat aspect shear modulus, shear strength and vertical aspect Transverse shear stress - strain curve "to" continuous fiber (unidirectional tape or fabric) reinforced polymer matrix composite laminates Latitude Determination of "shear properties; --- Remove 3.1 CKC cut definitions of terms, definitions of terms 0.2% increase shear strength; --- Increase in Chapter 4, the principle method; --- The test equipment included as a separate chapter (see Chapter 5), which adds provisions relating to the environment boxes (see 5.2); --- The width of the sample from the "25mm ± 0.5mm" to "25mm ± 0.1mm", delete the sample sheet strengthening requirements, Slice count should be enhanced layout and sample length parallel degree requirements (see 6.2); --- The "specimen thickness [45 °/-45 °] ns, wherein the unidirectional laminates (16, 20 or 24 layers), 4≤n≤6, arbitration sample thickness h The thickness of the plywood layer 3s. For fabric laminate (8, 12 or 16 layers), 4≤n≤6 "read." stacking sequence of samples [45/-45] ns (after sub-composite laminates paving repeated n times, then symmetrical paving). Wherein for unidirectional tape, 4≤n≤6; For fabric, 2≤n≤4 "(see 61, 2005 4.2.); --- Increased non-laboratory standard ambient conditions (see 7.1.2) in a test environment condition of; --- The sample conditioning an increase in the content of the wet state of the sample (see 7.2.2); --- Detailed description of the increase in the extensometer and strain gauges installed in 6.2 and 7.3; --- Increasing the percentage of measured bending requirements (see 7.3); --- Shear strength by the symbol "τbLT" changed to "S", the shear stress by the symbol "τnLT" changed to "τ", the shear modulus by the symbol "GLT" changed to "G12" (see 9.1, 9.2); --- Modify the definition of shear strength (see 9.1); --- Increase the strain range measuring shear modulus (see 9.2); --- Shear strength increased by 0.2%, 0.2% shear strain and shear strain limits of the concept (see 9.3, 9.4). The standard by the China Building Materials Federation, China Aviation Industry Corporation made. The standard fiber-reinforced plastic by the National Standardization Technical Committee of the National Standardization Technical Committee on Aircraft (SAC/TC435) Centralized. This standard was drafted. China Aircraft Strength Research Institute, China Aviation Industry Corporation Beijing Institute of Aeronautical Materials. The main drafters of this standard.
