Pultrusion GFRP materials can be customized for use in heavy-load applications where they are also exposed to high levels of creep stress and dynamic fatigue.
By learning from previous product developments, we can apply these to new product innovations and continue to push the boundaries of what can be achieved with pultrusion technology.
We leverage the physical properties of GFRP Composites (eg. tensile strength, flexural properties, fatigue resistance, corrosion & chemical resistance), matrix research, and customizing formulations, then adapt our GFRP Composite products to suit specific applications.
Customizing Composite Properties
Creep and Cyclic Fatigue
Resistance to creep and fatigue stresses are vital factors in GFRP composites as they directly influence their long-term performance.
In both cases, the amount of stress applied has a direct effect on long-term performance. Creep is the time-dependent deformation under constant load, affecting structural integrity over time. Fatigue is the degradation of mechanical properties under cyclic loading.
We have increased these properties for components such as those used in trampolines, replacing steel springs with composite rods.
High Flexural Strength
The demand for lightweight, durable, and high-strength materials drives interest in GFRP composites for structural applications.
We enhance flexural strength through advanced manufacturing techniques and careful quality control. Matrix modification improves interfacial bonding, enhancing overall flexural performance.
Increasing shear strength in GFRP composites involves optimizing fiber-matrix interfacial adhesion, selecting appropriate resin systems, and employing advanced manufacturing techniques. Well-controlled curing processes further contribute to the overall improvement of shear strength in GFRP composites.
Shear strength is critical for applications such as rockbolts for mines and tunnels.
