Fiberglass roving is a popular choice for spray-up and hand lay-up processes due to its high strength and versatility.In spray-up applications,continuous roving is fed through a spray gun,where it is chopped into short lengths and mixed with resin before being sprayed onto a mold.This technique allows for the rapid production of complex shapes and large structures,such as boat hulls and automotive components.The continuous nature of the roving ensures that the final product has high mechanical strength and durability.
In hand lay-up processes,fiberglass roving can be woven into fabrics or used as reinforcement in thick laminates.It is particularly suitable for applications that require high tensile strength and dimensional stability.Woven roving,for example,is a type of fiberglass fabric made from continuous roving that provides excellent mechanical properties and quick resin absorption.This makes it ideal for manual processes where speed and ease of handling are critical.
Fiberglass roving is also used in the production of Sheet Molding Compound(SMC).In this process,the roving is chopped and randomly deposited onto a resin paste,creating a material that is highly suitable for compression molding.The resulting SMC sheets are widely used in automotive and industrial applications due to their strength,durability,and ease of processing.
Overall,fiberglass roving is a versatile material that offers superior strength and performance in spray-up and hand lay-up processes.Its ability to quickly absorb resin and conform to complex shapes makes it an ideal choice for a wide range of composite manufacturing applications.
