2020 E-glass epoxy study licensable data

 

For marine and offshore structures, E-glass / epoxy composites offer an attractive blend of performance and cost. This study was conducted using a single E-glass fabric in combination with 10 epoxy infusion resin systems targeting the marine sector in 2020.

It reveals how the choice of resin system can significantly impact laminate strength retention after long-term seawater immersion.
