Measure the mechanical properties of innovative materials
Discover an array of techniques that a Texture Analyser can be applied to measure the mechanical properties of innovative materials.
Why measure the mechanical properties of innovative materials?
Measuring the mechanical properties of innovative materials is vital for understanding their potential applications and limitations. As industries and technologies such as 3D printing evolve, there's an increasing demand for materials that can meet specific, often rigorous, criteria. Mechanical properties are key to determining whether a material withstands the forces that are required to be applied to it without a compromise to its expected deformation. Understanding structural integrity properties such as tensile strength, elasticity, and hardness can guide researchers and manufacturers in determining where these materials can be best used, ensuring durability and functionality.
Additionally, such measurements can pinpoint any vulnerabilities early in the development process, allowing for timely modifications. This ensures that these materials are both cost-effective to produce and safe in their intended applications. Furthermore, having a comprehensive understanding of a material's mechanical properties aids in regulatory compliance and can provide a competitive edge in markets where material innovation is a key differentiator. In essence, assessing these properties offers a roadmap for the optimal utilisation of new materials, ensuring they meet the multifaceted demands of modern industries.
Suppleness, disintegration, scoopability, cling force, springiness… To quantify these novel mechanical properties, fresh, creative, original, and fantastic materials require new testing methodologies. These physical characteristics might be advantageous or disadvantageous. You can only control them if you can measure them.
Due to the empirical or imitative way that the Texture Analyser range can be applied, it is called upon time and time again for use in innovative areas of industry such as the creation and development of new materials.
Unbound by fundamental or standard methods and analysis options, the Texture Analyser provides the flexibility of method development unavailable in other materials testing instruments. For this reason, it is found in countless recent patents applications where testing solutions for the measurement of properties of new materials are required for mechanical testing problems which cannot be assessed by applying rigid, old-fashioned standard method approaches.
How a Texture Analyser can be applied to innovative material mechanical property measurement
The manufacture and development of materials requires a deep understanding of their intrinsic properties to ensure suitability for specific applications, to innovate, and to maintain consistent quality. Utilising a Texture Analyser for the measurement of mechanical properties in this domain provides a wide range of benefits:
- Quality control and assurance: Regularly assessing mechanical properties like tensile strength, compressibility, and adhesion ensures that produced materials meet desired specifications, leading to consistent product quality across batches.
- Innovative material development: When developing new materials or improving existing ones, the Texture Analyser provides empirical or fundamental data that helps researchers understand how changes in formulation or processing affect mechanical properties.
- Predictive modelling: By understanding mechanical behaviour, manufacturers can predict how materials will perform under specific conditions, enhancing reliability when incorporated into final products.
- Optimised processing parameters: The Texture Analyser can help ascertain how different manufacturing processes (e.g., extrusion, moulding) influence material properties, allowing for process optimisation.
- Validation of material claims: For materials that are marketed with specific claims like "highly flexible" or "ultra-durable", a Texture Analyser can provide the quantitative data needed to substantiate these claims, bolstering credibility.
- Material comparisons: When considering multiple materials for a particular application, comparative testing using a Texture Analyser can assist in selecting the most appropriate material based on objective mechanical property data.
- Failure analysis: Should a material fail in its intended application, analysing its mechanical properties can provide insights into the causes of failure, facilitating improved designs or processing methods.
- Cost-efficiency: By determining the exact mechanical properties needed for an application, manufacturers can avoid over-engineering or using excess material, leading to cost savings.
- Regulatory and standards compliance: Many industries have set standards for material properties to ensure safety and performance. Using a Texture Analyser ensures materials are compliant with these standards, aiding in certifications and regulatory approvals.
- Sustainability and eco-friendliness: As there's a growing emphasis on sustainable and environmentally-friendly materials, assessing and optimising the mechanical properties of biodegradable or recyclable materials ensures they can functionally replace traditional materials without compromising performance.
- Customisation for client needs: Different clients might have specific requirements for mechanical properties based on their end-use applications. Using a Texture Analyser, manufacturers can tailor-make materials that fit these unique specifications.
- Life-cycle analysis: Understanding how the mechanical properties of materials change over time and under various conditions can help in predicting their lifespan, degradation rate, and end-of-life behaviour.
In essence, the use of a Texture Analyser in the manufacture and development of materials allows companies to maintain quality, innovate effectively, meet regulatory requirements, and make informed decisions that can lead to cost savings, improved performance, and sustainability. This instrumental insight supports the entire material lifecycle, from initial development to end-of-life considerations.

New products that take new forms and have innovative properties require new testing solutions to ensure that the purpose for which they are designed is met and their structural or mechanical requirements match their intended location of use. A Texture Analyser is frequently relied upon for use in innovative fields of industry, such as the invention and development of novel materials, due to the empirical or imitative way in which it can be utilised. The Texture Analyser offers method creation flexibility not seen in other materials testing devices because it is not constrained by fundamental or standard methodologies and analysis possibilities. As a result of its universal application in all industries, it appears in a wave of recent patent applications where testing solutions for the measurement of properties of novel materials taking unusual sample forms are needed for mechanical testing challenges that can't be solved using rigid, old-school standard technique approaches.
