Thermal analysis in the automotive and aerospace industries
Innovations for mobility and aviation
In the automotive and aviation industries, the focus is on safety, energy efficiency and material reliability.
Every component – from engine parts to aircraft fairings – must function reliably under extreme conditions.
Thermal analysis provides crucial insights here: It enables the evaluation of thermal conductivity, thermal stability and expansion behavior and is therefore a key tool for research, development and quality assurance.
Materials under extreme conditions
Components in vehicles and aircraft are exposed to high temperatures, pressure differences and mechanical stress.
To meet these requirements, engineers must have precise knowledge of the behavior of metals, polymers, ceramics and composite materials.
Typical challenges:
Thermal stability: How does a material change with changing temperatures?
Thermal conductivity: How efficiently is heat dissipated within a component?
Sintering behavior and curing: How do production processes for ceramics, composites or adhesives work?
Aging processes: How do temperature cycles affect service life and performance?
LINSEIS’s modern thermoanalytical measurement techniques make it possible to answer the following questions, among others:
- At what temperature does a bumper warp?
- Which material is least susceptible to deformation on impact?
- Why does an embrittlement fracture occur in a molded part?
- If the curing cycle of a carbon fiber reinforced resin be shortened?
- Is the turbine material sufficiently thermally conductive to ensure good cooling?
- Which material can withstand the high thermal loads in the aerospace industry?
Thermal analysis methods at a glance
With modern Linseis measuring systems, all relevant parameters along the product life cycle can be determined:
Dilatometer (DIL): Measure thermal expansion and help to avoid stresses and deformations in materials.
Laser Flash Analyzer (LFA): Precisely determine the thermal conductivity of metals, composites or ceramics.
Thermal Diffusivity & Capacitance: Allow the evaluation of thermal management in electronic and structural components.
Differential Scanning Calorimetry (DSC): Examines melting and glass transitions – crucial for polymers, resins and adhesives.
Thermogravimetry (TGA): Analyzes decomposition, oxidation and moisture content.
Practical examples from the industry
Thermal conductivity in electrified vehicles
Thermal management plays a central role in electromobility. Batteries, power electronics and cooling structures must be optimally coordinated.
The Transient Hot Bridge (THB) can be used to precisely measure the thermal conductivity of insulating and heat-conducting materials.
The results enable efficient heat dissipation and extend the service life of electronic components.
Curing process of composite materials in aviation
For fibre composite components – such as aircraft fuselages or wings – precise control of the curing process is crucial.
Differential scanning calorimetry (DSC ) is used to analyze and optimize curing reactions.
This shortens production time, minimizes material defects and improves mechanical stability.
Material testing and quality assurance
Thermal analysis methods from Linseis provide support:
the characterization of new materials,
the optimization of production processes,
the simulation of real operating conditions and
the long-term monitoring of components.
This makes material behavior and process parameters transparent – a crucial prerequisite for safety, reliability and efficiency in modern mobility concepts.
Future prospects
Progressive electrification, lightweight construction concepts and sustainable manufacturing are increasing the need for precise material analysis.
Linseis offers solutions that help engineers develop innovative materials faster and reliably predict their behavior.
Whether in the automotive industry, aviation or aerospace – thermal analysis provides crucial data to make tomorrow’s technologies safer, more efficient and more durable.
