Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard is proposed by the China Building Materials Federation. This standard is under the jurisdiction of the National Fiber Reinforced Plastics Standardization Technical Committee (SAC/TC39). This standard was drafted. Aerospace Special Materials and Technology Institute. The main drafters of this standard. Wang Huaqiong, Zhou Jinshuai, Gao Zenghua, Zhou Zhiliang, Su Jiang, Xue Di. Quartz fiber fabric reinforced resin matrix composite Test method for high temperature mechanical properties

1 Scope

This standard specifies the general requirements, tests, test results, and experiment report. This standard applies to the tensile strength of two-dimensional woven structure quartz fiber fabric reinforced resin-based composites when the test temperature is not higher than 500 ° C. Testing of properties, compressive properties, bending properties and short beam shear strength. Other fiber-reinforced resin-based composite materials can be used as a reference.
