To enhance the performance and processing characteristics of fiberglass chopped strand composites, various typical additives are used. One such additive is a coupling agent, which promotes adhesion between the fiberglass strands and the polymer matrix. By ensuring a strong bond between the fiberglass and the resin, coupling agents improve the mechanical properties of the composite.
Another commonly used additive is a processing aid or lubricant, which enhances the flow and processing of the composite during manufacturing. These additives reduce friction between the fiberglass strands and the resin, facilitating the molding and shaping of the composite material.
Moreover, depending on the specific application or desired properties of the composite, other additives like fillers, pigments, and flame retardants may be employed. Fillers can enhance the stiffness and dimensional stability of the composite, while pigments provide color or aesthetic appeal. Flame retardants are added to improve the fire resistance of the composite material.
It is worth noting that the choice of additives for fiberglass chopped strand composites may vary based on the intended application and specific requirements of the end product. Manufacturers and engineers may opt for different additives to achieve desired properties such as strength, flexibility, durability, or resistance to environmental factors.

It is important to note that the specific additives used with fiberglass chopped strand composites can vary depending on the intended application and the specific requirements of the end product. Manufacturers and engineers may select different additives to achieve desired properties such as strength, flexibility, durability, or resistance to environmental factors.
The typical additives used with fiberglass chopped strand composites include resin binders, fillers, coupling agents, and processing aids. Resin binders are used to hold the chopped strands together and improve the composite's strength and durability. Fillers such as calcium carbonate or talc can be added to enhance hardness or reduce cost. Coupling agents improve the adhesion between the fibers and the resin matrix, while processing aids like lubricants or anti-static agents help with the manufacturing process.
