What is an interlaminar peeling testing machine?
In industrial production, the interlaminar peel strength of materials is an important performance indicator, especially in the fields of composite materials, adhesives, films and coatings. The interlaminar peeling tester is a device specially used to test the interlaminar peeling strength of materials. It is widely used in scientific research, quality control and product development. This article will introduce in detail the definition, working principle, application fields and popular models of the interlayer peel testing machine.
1. Definition of interlaminar peel testing machine
The interlaminar peeling tester is an instrument used to measure the interlaminar peeling strength of materials. It tests the bonding properties between material layers by applying a specific force. It can simulate the stripping conditions in actual use and provide scientific basis for material performance evaluation.
2. Working principle
The working principle of the interlaminar peel testing machine is to fix the sample through a clamp, then apply peeling force at a constant speed, and record the change in force value during the peeling process. The test results can reflect the bonding strength, uniformity and durability of the material.
3. Application areas
Interlaminar peel testing machines are widely used in the following fields:
| field | Application examples |
|---|---|
| composite materials | Test the interlayer bonding strength of composite materials such as carbon fiber and glass fiber |
| Adhesive | Evaluate the peel performance of adhesives |
| Films and Coatings | Test the bonding strength between the film and the substrate |
| packaging materials | Evaluate interlaminar peel performance of packaging materials |
4. Popular models in the market
The following are the popular interlayer peel testing machine models and their main parameters currently on the market:
| Model | maximum load | Test speed | Applicable standards |
|---|---|---|---|
