1 Scope

This document describes a test method for the adhesive properties of biomimetic dry adhesive materials.

This document is applicable to testing the normal adhesion strength, tangential adhesion strength, and 90° and 180° peel strength of biomimetic dry adhesive materials.

This provides a reference for interfacial contact mechanics testing of other similar biomimetic materials.

2 Normative references

The contents of the following documents, through normative references within the text, constitute essential provisions of this document. Dated citations are not included.

For references to documents, only the version corresponding to that date applies to this document; for undated references, the latest version (including all amendments) applies.

GB/T 16825.1-2022 Inspection and Calibration of Static Uniaxial Testing Machines for Metallic Materials - Part 1.Tensile and/or Compressive Testing

Inspection and calibration of the machine force measurement system

3 Terms and Definitions

The following terms and definitions apply to this document.

3.1

Surface and interface adhesion functional materials based on the micro-nano adhesion structures of the feet of terrestrial organisms such as geckos, beetles, and spiders.

3.2 Area of contact

The total apparent area of the biomimetic dry adhesive material sample when it comes into contact with the surface to be bonded.

Note. The actual contact area may be smaller than this apparent area.

[Source. GB/T 40721-2021, 3.2, with modifications]

3.3 preload force

The normal pressure perpendicular to the contact surface is applied to ensure good contact between the biomimetic dry adhesive material sample and the surface to be bonded.

3.4 Normal adhesive force

Under certain conditions, a biomimetic dry adhesive material sample forms an adhesive contact interface with the bonded surface, and the adhesive contact interface exhibits

The ability to resist separation perpendicular to the contact interface.

3.5 Tangential adhesive force

Under certain conditions, the adhesion contact interface exhibits the ability to resist separation parallel to the contact interface.

3.6 Peel force

Under certain conditions, the ability of the adhesive contact interface to resist peeling.
