Introduction

1. Background and significance of standard formulation

GB/T 33613-2017 "Test method for tensile properties of three-dimensional braided fabrics and their resin-based composite materials" is an important standard for tensile properties testing of three-dimensional braided fabrics and their resin-based composite materials. With the increasing application of composite materials in aerospace, automobile manufacturing, construction engineering and other fields, accurate evaluation of material properties is particularly important.

2. Comparison of standard frameworks

Standard dimensions	GB/T 33613—2017	Comparative analysis
Scope of application	Three-dimensional braids and their resin-based composites	Not applicable to three-dimensional braids with special-shaped structures
Test principle	Apply a tensile load uniformly along the length of the specimen until the specimen breaks, and record the load and elongation during the stretching process	Consistent with GB/T1446-2005
Definition of terms	Including professional terms such as three-dimensional braided fabrics, resin-based composite materials, unit cell length, unit cell width, etc.	New concepts such as braided unit cell and knot length

3. Recommendations for standard implementation

Specimen preparation: Both ends of the fabric specimen need to be cured, and the curing process in Table A.1 is recommended. Composite specimens must ensure that the structural integrity is maintained after molding or machining.

Implementation case analysis

An aerospace company used the GB/T 33613-2017 standard to test the tensile properties of three-dimensional braided composite materials. The results showed that its breaking strength and elastic modulus met the expected requirements. Through the implementation of this standard, the company has significantly improved the accuracy and consistency of material performance evaluation.
