Characterization of Composite Materials

Characterization of advanced composite materials guarantees that they meet the application performance requirements for their intended use in industry.

Material characterization for composites is an important aspect of the product development and manufacturing process. Physical and chemical characterisation aids developers in gaining a better understanding of goods and materials, allowing for better quality control.

Our composite material characterization services guarantee that products meet stringent industry standards. This includes, among other things, the aerospace, automobile, consumer, medical, and defence industries. Understanding the characteristics and performance of a material is a crucial concern for suppliers, producers, and developers, given the enormous number of lay-ups, prepregs, resin systems, adhesives, and reinforcements available. This holds true for the whole composite supply chain.

We are a one-stop solution supplier with our global composite teams, specialising in material pre-screening, specimen preparation, long-term exposure, and detailed mechanical characterization to ASTM, ISO, and IN standards utilising industry-specific procedures.

Support for formulation, development, and research:
Our composite experts will help you build your formulation, ensuring that the qualities fulfil the requirements for the application.

Sanray specialises in the identification and characterisation of composites utilising spectroscopic, thermal, and rheological techniques. Curatives, formulations, resins, and filled systems are generally studied using these approaches, either during processing or as finished products. Our ability to considerably speed up the material selection process for thermosetting matrices used in composites, especially when compared to standard characterizing methods, is one area of focus.

Material Characterization (Mechanical and Physical)
Mechanical, optical, thermal, electrical, exposure, flammability, surface and barrier characteristics, and exposure are just a few of our physical property testing capabilities. Chemical properties, such as emissions, are also tested.
Sanray specialize in quick turnaround mechanical evaluations using cutting-edge mechanical characterization tools such as:

  • Load cell capacity of up to 250kN
  • Using Align Pro to meet Nadcap accuracy criteria for tension and Hydraulic Composite Compression Fixture (HCCF) for compression, data precision is improved by reducing bending effects.
  • High-temperature extensometers with an 8-channel strain gauge
  • Temperature chamber testing at raised and decreased temperatures.

Clients benefit from our scientists’ knowledge of stress/strain graphs, hardness, toughness, impact resistance, corrosion, dielectric strength, density, electrical conductivity, thermal expansion, UV deterioration, and other subjects. This data is used to predict how a product will react to external influences like as vibration, heat, fluid flow, and other physical phenomena.

Non-destructive testing (NDT) is a type of non-destruct (NDT) Composite Material C-scan
Prior to verifying mechanical qualities, NDT pre-scanning evaluates the quality of composite materials by scanning for damage or material inconsistencies.

Preparation of Specimens:

Specimen preparation is a key stage in proving the materials’ reliability, as it aids in the consistent and quick production of composites, which are critical in automotive and aerospace applications. Using state-of-the-art plate saws, our professional machinists maintain the parallelism required for rectangular specimens for precise mechanical data production. The addition of tabbing and strain gauges to the wide capabilities for specimen preparation completes the picture.
