About me


Luciano Avila Gray, M.Sc.

I am a passionate materials scientist with experience ranging from scientific research to industrial application.

My qualifications allow me to relate atomic and crystalline structures with material properties and comprehend the effects of the manufacturing processes on the microstructure. I have extensive experience in characterization at both, the micro and macro levels, using a wide range of techniques including microscopy, diffraction, spectroscopy, thermal analysis, and mechanical testing.

Between 2013 and 2024, I occupied leading positions at the Chair of Carbon Composites of the Technical University of Munich, where I supervised and guided more than a dozen research associates in their research and Ph.D. projects.

Some of the topics were: developing and optimizing manufacturing processes, online process monitoring, material characterization, simulation, and additive manufacturing.
I have also been in charge of numerous direct industry contracts.

Research and Development

Unlocking the Material´s Potential

I offer a generalist approach to materials research and engineering covering its development, characterization and degradation as well as process development and optimization.

The collaboration can be flexibly adapted to your needs, whether as an independent contractor, as part of your team for the duration of an internal development project, or as a sub-contractor for a specific work package.
I can also be a qualified and valuable companion in publicly funded research projects.

Areas of work

  • Project planning and management
  • Experimental design, plan, and execution
  • Team lead and coordination
  • Analysis and interpretation of experimental data and results
  • Case study and solution recommendation
  • Survey and analysis of the state of the art

Some of the questions I can help you answer:

  • Why does the material have these properties and not those expected? What is its micro-structure?
  • What is the necessary micro-structure and composition for the material? How can it be obtained?
  • How can the manufacturing process be more efficient maintaining or improving the material´s properties?
  • What characterizations methods can be used to solve a problem?
  • What do these experimental results mean?
  • How can the necessary material parameters for a simulation be obtained?
  • Which material is appropriate for my application?
  • How will a material degrade in time?
  • How does the material creep, relax or behave under dynamic loading?

Affordable Mechanical Characterization

Guiding Small Business towards Higher Performance

Many industries and manufacturers could improve if they had access to the appropriate characterization methods.
For that reason, I offer affordable and streamlined mechanical testing, aimed in particular at small businesses.

One of the most used methods is bending, due to its low cost and easy sample preparation, setup, and speed. It is a very convenient benchmark used to compare properties, optimize processes, and for quality control.

Other test methods up to 2500N are also offered.

Characterization methods in-house

  • 3 and 4 point bending
  • Tension and compression
  • ILSS (Interlaminar shear strength)
  • Interlaminar energy release rate.
    • Mode I: Double cantilever beam
    • Mode II: End notched bending.
  • Peel: Wedge and T-peel
  • Adhesion test

Equipment

  • Universal testing machine Hegewald & Peschke Inspekt Solo 2,5 kN
    • Maximum load: 2500 N and 50 N
    • Maximum speed: 1200 mm/min
    • Maximum test displacement: 1250 mm
  • Strain Measurement
    • 2D bi-axial extensometry. Multiple resolutions, frame rates and fields of view
    • 2D and 3D digital image correlation
    • Strain Gages

Tensile test setup of a 3D Printed PLA sample

DIN 527-4 Type B coupons 3D printed in the three main directions. Every print direction produces different structures and properties.

Scanning Electron Microscopy (SEM) is a very useful technique for fracture analysis.

The mechanical behavior of plastics is usually discribed with several viscoelastic parameters. They can be determined using creep, relaxation and oscillatory DMA test.

Material properties like glass and melting temperatures, crystallinity or degree of cure can be measured with Dynamic Scanning Calorimetry (DSC) and used to optimize process parameters.

Characterization Campaigns

Expert Support in Multi-Level Characterization

Some questions cannot be answered solely by examining a material’s mechanical properties. A broader perspective, achieved by applying different techniques, can often better explain the underlying causes.
I offer one-stop characterization services in cooperation with partner institutes.

  • Optimizing the campaign by selecting the most effective and
    cost-efficient experiments.
  • Planning the schedule, number of samples, and test parameters.
  • Sample preparation, tests, and analyzing and interpreting the data.
  • Reporting the results, explaining the causes and solutions to the problems, and providing recommendations.

Mechanical Characterization

  • Universal Testing Machines: Electromechanical, Servo-hydraulic
  • Split Hopkinson Bar
  • Drop hammer (Charpy, IZOD)
  • Hardness
  • Characterization under controlled conditions (temperature and humidity)

Strain Measurement
