Fiberglass Guide: Things You Need to Know about Fiberglass Roving
Due to its strength, durability and versatility, fiberglass roving has been widely used in many areas such as building construction, corrosion resistance, energy-saving, transportation etc. It is mostly used as a reinforcement for composite materials, offering supplementary strength, stiffness and other functional properties.This article will show you the different types of fiberglass roving available in the market, their properties and applications.
What is the difference between fiberglass direct roving and assembled roving?
Fiberglass Multi-end roving is also called assembled roving. The expression “multi-end” indicates that the fiberglass strand has a specific number of splits or ends. In contrast, a direct roving or single-end roving has only one end – only one full strand.
What is the TEX of fiber?
Tex is a unit of measure for the linear mass density of fibers, yarns and thread and is defined as the mass in grams per 1000 meters. For example, fiberglass 2400 tex, means the weight of 1000 meters fiberglass roving is 2400 grams. Fiberglass 4000 tex, means the weight of 1000 meters fiberglass roving is 4000 grams
ECR Fiberglass direct roving is a type of roving that is produced using an advanced manufacturing process that brings a higher level of fiber alignment and reduced fuzziness. ECR glass fiber, boasts alkali and acid resistance, good heat resistance, low electrical leakage, and superior mechanical strength compared to E-glass. It is also very environmentally friendly and used to create durable, transparent fiberglass-reinforced panels. Its composition comprises materials with alkali and acid resistance, high heat resistance, waterproof properties, and mechanical strength. It is generally used in applications where high strength, stiffness, and dimensional stability are required, such as in the production of wind turbine blades and aerospace components.
Fiberglass yarn is a type of fiberglass that is made by twisting together several strands of glass fibers. It is generally used in applications where high strength and heat resistance are required, such as in the production of insulation materials and electrical components, like fiberglass mesh, fiberglass fabric for electrical insulation.
the compound manufacturing process. And in the following process like compression molding using SMC, the fibers also have excellent mold flowing characteristics and can be distributed homogeneously, thus resulted in great laminate mechanical properties and class “A” surface in a range of applications，such as auto parts, truck body panels and grill opening panels etc.
