Non-Metallic Material Error Test

EUROLAB performs error analysis of a wide variety of non-metallic materials, including error analysis of rubbers, adhesives, sealants, paints, coatings and composites.

Non-Metallic Material Error Test

Non-metallic material error analysis presents a unique challenge because the primary error analysis sequence remains the same, while fractographic interpretation and analytical testing are very different from those used on metallic materials.

Due to many material formulations and combinations, EUROLAB's non-metallic material error analysis laboratories often use dense material identification programs to help identify the source of the fault.

What are the differences between non-metallic and metallic material tests?

Unlike metals, a non-metallic material cannot typically be identified by any technique. Often, chemical analyzes are combined with a thermal properties test to create a clear picture of the material's identity and source. Non-metallic materials are evaluated in terms of their structural properties and defects in this structure and the root cause of failure.

Non-metallic material failure analysis

Common Non-Metallic Materials Analyzed

  • acrylics
  • Carbon Fiber Reinforced Polymers (CFRP)
  • Glass Fiber Reinforced Polymers (GFRP)
  • polybutylene
  • polythene
  • Polymer Matrix Composites (PMCs)
  • Polymers and Plastics
  • Polypropylene Polytetrafluoroethylene (PTFE)
  • Polyvinyl Chloride (PVC)
  • Rubbers and Elastomers
  • Silicon Carbide

Malfunctions associated with these materials are often the result of a wide variety of mechanisms and factors, such as:

  • Production errors / contamination
  • Chemical exposure (environmental stress cracking, chemical contact)
  • Infection
  • Adverse environmental conditions in service (exposure to temperature, humidity, UV rays)
  • Molecular degradation (molding process, service conditions)
  • Molding defects (inclusions, voids, knitting lines)
  • Stress concentration (design features, flaws)
  • Fast deformation (impact, plug-in assemblies)
  • Longer under stress / creep
  • Fatigue loading
  • Finding the root cause of the error

While the primary purpose and identification of the associated responsibility of any error are primary goals, added value is provided in preventing future events. EUROLAB experts understand this and provide real-life solutions to financial failure challenges.
