Your prepreg passed every lab check. But… the part still came out of the autoclave with voids. DSC confirmed the resin reacted. It did not tell you when flow stopped, when gelation started, or how much modulus the material built. Open-cavity rheometers run under no applied pressure, so volatiles might escape and resin can migrate out of the measurement zone. The problem? Production never runs under those conditions. ASTM D7750 measures the full progress of dynamic mechanical properties during cure inside a sealed, pressurized cavity. One specimen returns four data sets: 💧 Viscosity ⏱️ Cure behavior ❄️ Glass transition temperature ↔️ Solid-state moduli On September 22, Berrin Degirmenci, PhD provides an overview of the standard and specimen prep, four methods for finding the gel point, and how to read a complete D7750 output from minimum G’ through post-cure Tt.

What if you could double your rubber testing capacity without doubling your bench space? For all other MDRs, a single die sets the ceiling on your rubber testing. When cure testing backs up, batch releases wait, and adding capacity used to mean buying a second MDR and giving up space. Not anymore. Our new Premier MDR DUO removes the tradeoff. Two die sets in a single patent-pending instrument test two samples at the same time, so you get: ⚙️ Double the testing capacity in the same space 💰 Lower upfront and maintenance cost than two separate MDRs 🔧 The same certified Alpha OEM parts, software, interface, and workflow your operators run today 📋 No new SOPs and no retraining 📊 Cure and foaming measurement, up to 224 samples queued for automated testing Same platform your team trusts at twice the pace.

Every detail counts when it comes to composite strength. Learn how to control cure temperature, ramp rates, and layup orientation for better results. Alpha Technologies’ latest research has the insights you need to optimize your prepreg materials.

Every engineer knows that small adjustments can make a big difference. Using the Encapsulated Sample Rheometer (ESR), Alpha Technologies’ experts have measured how cure rate, out-time, and fiber orientation affect the reliability and strength of your prepregs.
