mychoiii Marine Grade 1708 Biaxial Glass Fiber Roll Structure & Composition Bidirectionally woven (0° and 90° directions) continuous glass fibers, with two layers of fibers plus one layer of chopped strand mat (typically 50gsm). Needle-punched or stitched (emulsion-free), with a total weight of 1000gsm. Process & Construction Low resin consumption, slower curing speed. Processes: hand lay-up, vacuum infusion, RTM. Mechanical Properties High strength, balanced bidirectional load-bearing for main load-bearing structures. High tensile strength, excellent impact resistance. Interlaminar bonding with delamination risk at the fiber-mat interface. Cost & Durability Dense structure prevents medium penetration; good long-term performance. Good fatigue resistance for dynamic load environments. Typical Application Scenarios Main load-bearing structures like ship hull keels and decks. High-load components such as high-pressure tanks and wind turbine blades.
