Composite systems have two sub-constituents: woven fibers as the reinforcement element and resin as the matrix. The most commonly used fibers are glass and carbon, which can be processed in plane or satin structures to form woven fabrics. Carbon fibers, in particular, are known for their high strength/weight properties.
Thermoset resins, such as epoxies and polyurethanes, are used in more demanding applications due to their high physical-mechanical properties. However, composite manufacturers still face the challenge of designing cure cycles and repairing out-of-shelf-life parts.
To address these issues, Alpha Technologies proposes using the encapsulated sample rheometer (Premier ESR) to determine the viscoelastic properties of thermosets.
Premier ESR generates repeatable and reproducible analytical data and can measure a broad range of viscosity values.
Ideal for low-viscosity uncured prepreg or neat resins as well as highly viscous cured prepregs.
Before-cure, cure, and after-cure properties can be detected without removing the material from the test chamber.
From isothermal and non-isothermal cures to advanced techniques such as large amplitude oscillatory shear tests.
