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.
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 evaluates a material’s stiffness, modulus, and resistance to cracking under combined tension and compression. For laminates and coatings, flexural testing provides critical insight into load-bearing capacity and surface integrity.
We perform testing in accordance with ISO 178, generating detailed stress-strain data to guide resin selection, laminate design, and curing optimisation.
Compression Testing
Compression testing determines how materials behave under compressive loads, identifying crushing strength, modulus, and failure mode. This test is particularly useful for polymer concretes, filled epoxies, and composite cores where compressive resistance directly influences structural stability.
Our controlled loading setups ensure repeatable, high-accuracy results even for small or irregular samples.
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 provides a quick and reliable measure of surface hardness for cured resins, coatings, and composites. It is an industry-standard indicator of degree of cure, surface finish, and mechanical uniformity.
Regular hardness checks are an effective method for in-process quality control and for verifying full cure in field-applied or cast systems.

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.
