Our spray up roving, combined with premium fiberglass, is meticulously engineered to address the exacting requirements of composite manufacturing, specifically in the spray-up process. This versatile fiberglass roving serves as a fundamental element in crafting composite structures known for their remarkable strength, durability, and efficiency.
Here are four key features of spray up roving:
● Chopped Fiber Structure: Spray up roving consists of short, discontinuous fibers, ideal for spray-up molding processes to create complex composite shapes with ease.
● Excellent Dispersion: Designed for uniform distribution during spraying, spray up roving ensures consistent reinforcement and minimizes fiber clustering in molds.
● Rapid Resin Wetout: Spray up roving absorbs resins quickly, enabling efficient impregnation and reducing air entrapment for smooth, void-free composites.
● Balanced Mechanical Performance: Offering reliable tensile strength and impact resistance, spray up roving delivers robust structural integrity for applications like boat hulls and automotive parts.
