Analysis of combustion and thermal performance test methods for automotive non-metallic materials

Analysis of combustion test methods and thermal properties of non-metallic materials for vehicles

1. Thermal Properties of Non-Metallic Materials 1. Definition of Thermal Properties Thermal properties of polymer materials refer to the relationship between polymer materials and total heat or temperature performance. It includes many aspects, such as the effect of temperature on various mechanical properties, glass transition, viscous flow transition, melting transition and thermal stability, thermal expansion and thermal conduction. This is one of the important properties of polymeric materials.

2. Thermal properties of non-metallic materials

1. Definition of thermal properties

Thermal properties of molecular materials refer to the sum of the properties of molecular materials related toheat or temperature. . It includes many aspects, such as the effect of temperature on various mechanical properties, transformation, low viscosity transition, melting transition and thermal properties, thermal expansion and thermal conduction. This is one of the properties of molecular materials.

2. Purpose and significance of the test

Measure the changes of substances during the heating or cooling process to study the properties and changes of substances, or identify fractals of matter. It has a wide range of applications in the characterization of thermal properties, physical energy, mechanical properties and material properties, and it is of great importance for materials research and quality control of materials.

3. Commonly used thermal analysis techniques

There are different types of methods thermal analysis. According to the induction and classification of the International Thermal Analysis Association (ICTA), the current thermal analysis methods are divided into nine categories and seventeen types, in these thermal analysis techniques, thermogravimetry (TGA) , diff Differential scanning calorimetry (DSC), thermomechanical analysis (TMA), steady-state heat flux method and laser flash method are the most widely used.

3.1 Thermogravimetry (TGA)

Aim of the test: Thermogravimetric detection of substances Instrument of temperature -Mass change relationship, calculating the amount of substance.

Scope: research, process optimization and quality control in various fields such as plastics, coatings, pharmaceuticals, catalysts, inorganic materials, metallic materials and composite materials.

Test temperature range: room temperature ~1000℃
