Hybrid glass and polypropylene epoxy laminates resist seawater better over 30 days
Source: MDPI Polymers, "Study of Hybrid Epoxy Resin Composites Reinforced with E-CR Glass Fiber/Polypropylene: Moisture Behavior, Mechanical Strength, and Acoustic Damage Mitigation Under Marine Aging Conditions", published 5 November 2026.
What the source says
Peer-reviewed study finds E-CR glass/PP hybrid epoxy composites cut short-term seawater moisture uptake and kept higher residual flexural strength after 30 days.
Allbase view
A single lab study of E-CR glass and polypropylene hybrid epoxy laminates, aged in seawater for 30 days. Promising for marine work, but a month is short and nothing here changes a specification today: nothing to act on yet.
