Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard replaces GB/T 3356-1999 "plastic flexural properties of unidirectional fiber reinforced." This standard and GB/T 3356- Compared to 1999, the main changes are as follows. --- Standard name from "plastic flexural properties of unidirectional fiber reinforced" with "directional fiber reinforced polymer matrix composites bend Music performance test method "; --- Expand the scope of application. polymer matrix composites Laminates bending properties of continuous fiber reinforced determination; --- Principle of the method of directional fiber-reinforced polymer matrix composites flexural properties were described; --- The test equipment included as a separate chapter (see Chapter 5), which adds provisions relating to the environment boxes, and provides for loading and head carriage The hardness, HRC40 ~ 45. 5.3 The test method has been described to retain the original three-point bending test side (Method A), an increase of four-point bending test method (Method B), the radial load bearing head and instead of polymer matrix composites Load bearing material samples and head radius. R = 3mm, to 0 ° unidirectional fiber-reinforced composite laminate specimen loading head and branched Block radius. R = 5mm; --- Chapter 6 in the specimen shape and size, in addition to retain the contents of the original standards, the increase of polymer matrix composites specimen thickness Requirements, 2mm ~ 6mm, recommend 4mm (see 6.1). --- Chapter 7, delete the test equipment and test machine calibration two, the test laboratory environmental conditions into standard ambient conditions (see 7.1.1) and non-laboratory standard ambient conditions (see 7.1.2). For conditioning the sample into the dry state (see 7.2.1) and wet Sample state state (see 7.2.2); --- Original standard span adjustment, accurate to within 0.5mm to span measurement is accurate to 0.1mm (see 8.2.1); --- Increased sample failure mode description (see 8.3.4); --- Chapter 9 increased bending calculations, calculated failure strain of four points (see 9.1.2) and calculate the flexural modulus Recommended strain range 0.001 to 0.003 (see 9.1.3). The standard by the China Building Materials Federation, China Aviation Industry Corporation made. The standard fiber-reinforced plastic by the National Standardization Technical Committee, the National Standardization Technical Committee on Aircraft (SAC/TC435) Centralized. This standard was drafted.
