Designing Cure Cycles for Composites
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.
The Encapsulated Sample Rheometer
To address these issues, Alpha Technologies proposes using the encapsulated sample rheometer (Premier ESR) to determine the viscoelastic properties of thermosets.
Repeatable, reproducible data
Premier ESR generates repeatable and reproducible analytical data and can measure a broad range of viscosity values.
Low to high viscosity
Ideal for low-viscosity uncured prepreg or neat resins as well as highly viscous cured prepregs.
One chamber, every stage
Before-cure, cure, and after-cure properties can be detected without removing the material from the test chamber.
Broad range of tests
From isothermal and non-isothermal cures to advanced techniques such as large amplitude oscillatory shear tests.
