Learn More About our Mechanical Testing Abilities

Mechanical testing gives you real-world confidence in how your resin or composite will perform once it’s out of the lab and in use. Whether you’re producing structural components, coatings, or adhesives, our testing helps you understand how your materials handle stress, strain, and long-term wear - and where they can be improved.


All our tests are carried out in accordance with relevant AS and ISO standards, so you can trust that your results are accurate, reproducible, and industry-compliant.

Mechanical Testing of Resins, Adhesives, and Composites

Mechanical testing verifies the strength, stiffness, and durability of resin systems, adhesives, and fibre-reinforced composites. At Resin Services, we conduct a comprehensive range of mechanical tests to quantify performance, validate product specifications, and guide formulation improvement.


Our laboratory is equipped for both standardised AS and ISO methods and customised test programs tailored to specific product requirements, ensuring clients receive reliable and actionable mechanical data.

Blister Boil Testing (AS1838 Appendix F)

Blister boil testing assesses the resistance of a cured resin or coating to hydrolytic degradation under conditions of high heat and water immersion. It’s a critical durability test for materials used in wet environments, such as pool linings, waterproof coatings, adhesives, and polymer concretes.


Following AS 1838 Appendix F, test samples are subjected to boiling water exposure over a defined period to identify blistering, delamination, or softening of the surface layer. This procedure provides a rapid indication of water resistance, cure completeness, and long-term stability of thermosetting resin systems.


By performing blister boil testing early in the development process, we help clients verify material suitability for continuous or intermittent water contact applications and compare the performance of different resin formulations under identical conditions.

Tensile Testing

Tensile testing helps you understand how strong and flexible your material is when pulled apart. It’s a key indicator of performance for laminates, adhesives, and structural parts.


Tensile testing measures a material’s ability to withstand axial loading, providing data on tensile strength, modulus of elasticity, and elongation at break. This is essential for assessing bond line performance, fibre orientation, and resin toughness in both neat and reinforced systems. This test complies with ISO 527.


By comparing tensile properties before and after formulation changes, clients can identify improvements in ductility, crosslink density, or reinforcement efficiency.


We can help you pinpoint ultimate strength, modulus, and elongation, so you can compare formulations or ensure your product meets specification before production.

Flexural Testing

Flexural (bending) testing is a crucial evaluation method that assesses a material’s stiffness, modulus, and its ability to resist cracking when subjected to combined tension and compression forces. This testing is particularly important for laminates and coatings, as it offers critical insights into their load-bearing capacity and overall surface integrity. By understanding how these materials respond to bending stresses, manufacturers can make informed decisions regarding their applications and performance.


Our testing procedures are conducted in accordance with ISO 178, which ensures accuracy and reliability in the data we collect. This rigorous testing generates detailed stress-strain data that serves as a fundamental guide for various processes, including resin selection, laminate design, and the optimization of curing techniques. With this information, we can enhance the durability and efficiency of our products, ensuring they meet the demands of their intended applications.

Compression Testing

Compression testing is a crucial process that helps determine how various materials behave when subjected to compressive loads. This testing not only identifies key properties such as crushing strength, modulus, and failure mode but also provides valuable insights into the material's overall performance under stress. Such assessments are particularly beneficial for materials like polymer concretes, filled epoxies, and composite cores, where the ability to withstand compressive forces is vital for ensuring structural stability and integrity.


To achieve reliable results, our controlled loading setups are meticulously designed to guarantee repeatable and high-accuracy outcomes, even for small or irregularly shaped samples. This precision allows for a comprehensive understanding of material behavior, which is essential for informed engineering and design decisions..

Fibre Fraction / Ply-by-Ply Analysis

Understanding the fibre-to-resin ratio is essential for predicting how a composite will perform under stress.


For fibre-reinforced composites, understanding fibre volume fraction and ply composition is essential for predicting performance and validating manufacturing consistency.


Using chemical digestion and microscopy, we accurately quantify fibre, resin, and void content, as well as individual ply thickness and orientation. This data supports quality control, failure analysis, and laminate optimisation for aerospace, marine, and civil composite applications.


Using microscopy and chemical digestion methods, we can analyse the fibre volume fraction and layer-by-layer construction of your laminates to help you optimise manufacturing consistency and structural efficiency.

Peel Testing

Peel testing evaluates how well an adhesive or coating bonds to its substrate.


Peel testing quantifies adhesive strength and interfacial bonding performance between resin systems and substrates. Resin Services performs 90-degree, T-peel, and floating roller peel tests to evaluate surface preparation, adhesive formulation, and cohesive failure modes.


These results help manufacturers identify weak interfaces, validate surface treatment processes, and enhance durability under service conditions.


Whether you’re developing epoxy adhesives, laminates, or surface coatings, we can help you quantify peel strength and identify where the failure occurs, whether that's in the bond line, the substrate, or the interface, you will know exactly how to improve adhesion.

Barcol Hardness Testing

Barcol hardness testing is a highly efficient and dependable method for assessing the surface hardness of various materials, including cured resins, coatings, and composites. This testing technique has become an industry-standard indicator, offering valuable insights into the degree of cure, surface finish quality, and overall mechanical uniformity of these materials.


Incorporating regular hardness checks into the production process serves as an effective method for maintaining quality control during processing and for verifying that materials have achieved full cure, whether they are applied in the field or cast in pre-formed systems. These ongoing assessments not only enhance product reliability but also ensure that the final results meet industry standards and customer expectations.
