GB/T 45473-2025Composites and reinforcements fibres - Carbon fibre reinforced plastics(CFRPs)and metal assemblies - Determination of the cross tension strength (English PDF)

Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1: Structure and drafting rules for standardization documents" Drafting.

This document is equivalent to ISO 24360:2022 Composite materials and reinforcing fibers - Carbon fiber reinforced plastics (CFRPs) and metal composites. Determination of cross tensile strength of components. The following editorial changes were made to this document.

--- Deleted the "Safety Statement" which is not applicable to my country's actual situation;

---Change "the bonding area is a 25mm×5mm square" to "the bonding area is a 25mm×25mm square", combined with ISO 24360:2022 context, this is an editorial error (see Chapter 4);

--- The color marking of type B specimens has been changed, and the corresponding index numbers have been added (see Figure 1);

--- Deleted the nut on part 6 in the "Schematic diagram of the test fixture for the specimen in tensile mode" (see Figure 4);

--- Added the unit description of the bonding zone size in Figure A.1 (see Appendix A).

1 Scope

This document describes the method for determining the cross-tension strength of carbon fiber reinforced plastics (CFRPs) bonded to metal assemblies.

This method is applicable to the determination of samples bonded to metal components using carbon fiber reinforced plastics.
