T/XJBX 0089-2025 Guidelines for testing the mechanical properties of building composite materials
Basic Information
Scope
Architectural composite materials are composed of two or more materials with different properties. Through the synergistic effect between materials, their mechanical properties, durability, and functionality are significantly improved. In modern construction projects, composite materials are widely used in structural components, curtain walls, insulation systems, and functional building materials. Their mechanical properties directly affect the safety, durability, and service life of building structures. Mechanical property testing is an important means of evaluating the reliability of architectural composite materials in practical engineering applications, including compressive strength, tensile strength, flexural strength, shear performance, impact toughness, fatigue life, and fracture toughness. With the increasing variety of architectural composite materials and application scenarios, testing methods and standard requirements are becoming increasingly diverse, and traditional single testing methods have difficulty in comprehensively evaluating material performance. At present, there have been certain studies and applications of testing methods for architectural composite materials at home and abroad, but there are still problems such as inconsistent testing methods, large differences in experimental parameters, and inconsistent data analysis standards in actual engineering projects, which affect the comparability of testing results and the safety of engineering applications. Therefore, this document is designed to standardize testing methods, processes, equipment use, and data processing, and to provide systematic and standardized technical guidance. This document is applicable to the mechanical property testing of all types of architectural composite materials, providing a technical basis for scientific research institutions, testing units, and engineering applications to ensure the reliability, accuracy, and comparability of testing data.
