Various methods, such as hand layup, spray-up, and filament winding, are commonly used to incorporate fiberglass chopped strand into composite manufacturing processes.
In the hand layup method, the chopped strand is dispersed onto a mold or tooling surface made of either metal or composite material. The resin, typically thermosetting, is then manually applied over the chopped strand using a brush or roller. This manual application allows for precise control over the orientation of the fibers and distribution of the resin, resulting in a composite product that is strong and durable.
Another method, spray-up, involves spraying a mixture of chopped strand and resin onto a mold surface using a chopper gun. The gun combines the chopped strand and resin, cutting the strand into short lengths while mixing it with the resin. This mixture is then sprayed onto the mold, facilitating a rapid and efficient production process. The sprayed chopped strand is evenly distributed, resulting in a high-quality composite with excellent strength and stiffness properties.
Filament winding is a commonly used process for manufacturing cylindrical or tubular composite structures, such as pipes or pressure vessels. In this method, continuous strands of fiberglass are pulled through a resin bath, impregnating them with the appropriate resin. These wet strands are then wound onto a rotating mandrel in a precise pattern, forming a composite structure with exceptional strength and durability.
In summary, fiberglass chopped strand is a versatile material that can be incorporated into composite manufacturing processes using various techniques. Each method offers unique advantages in terms of production speed, control over fiber orientation, and overall product quality.

Spray-up is another method where a mixture of chopped strand and resin is sprayed onto a mold surface using a chopper gun. The chopped strand and resin are combined in the gun, which cuts the strand into short lengths and simultaneously mixes it with the resin. This mixture is then sprayed onto the mold, allowing for a rapid and efficient production process. The sprayed chopped strand is evenly distributed, resulting in a high-quality composite with excellent strength and stiffness properties.
Filament winding is a process commonly used for manufacturing cylindrical or tubular composite structures, such as pipes or pressure vessels. In this method, continuous strands of fiberglass are pulled through a resin bath, impregnating them with the appropriate resin. These wetted strands are then wound onto a rotating mandrel in a precise pattern, forming a composite structure with exceptional strength and durability.
Overall, fiberglass chopped strand is a versatile material that can be incorporated into composite manufacturing processes using various techniques, each offering unique advantages in terms of production speed, fiber orientation control, and overall product quality.
Fiberglass chopped strand is incorporated into composite manufacturing processes by mixing it with resin to create a reinforced composite material. The chopped strands are evenly distributed throughout the resin, providing strength and reinforcement to the final composite product. This mixture is then molded or laid up in specific shapes or layers and allowed to cure or solidify, resulting in a durable and lightweight composite material.
