Investigating UV Exposure and Thermal Cure in Vat Photopolymerization

NETZSCH Photo DSC Vat Photopolymerization

During the Vat Photopolymerization process, the component is built-up in layers in a liquid resin vat using a UV laser beam to selectively cure the resin. Learn how the degree of thermal cross-linking of a two-component resin is determined by the preceding cross-linking reaction during photo-polymerization.

How to Detect Cure State of Pre-Cured Composite Samples

CFRP Helicopter NETZSCH TM DSC

Popular materials for lightweight applications are glass and carbon fiber-reinforced plastics. The properties of the composite material are determined by the manufacturing process conditions. Therefore, it is crucial to know the curing state reached during manufacturing as well as the correlation between the glass transition temperature and degree of cure.

Optimize the Curing of Composites with Kinetics Neo

BLACKS Composites SRL and NETZSCH Analyzing & Testing made the next milestone in its already proven Partnership: Improving the curing of a CFRP bike rim with a simultaneous drastic reduction of the cycle time during cross-linkage. The bike rim was processed through hand lay-up technology and a subsequent autoclave curing. Saving cycle time with a better curing is not possible? It is! Based on the data of a differential scanning calorimeter and the simulation software Kinetics Neo, the cycle time was reduced by 46% compared to the cure cycle suggested by the material data sheet. Additionally, a higher degree of cure could be achieved to meet the target curing and avoiding overheating effects of the product.
