The adhesion of resin to fiberglass chopped strand is significantly affected by the surface treatment. During the manufacturing process, fiberglass chopped strand is typically treated with a sizing agent to improve its compatibility with resin systems.
The purpose of this surface treatment is to establish a chemical bond between the chopped strand and the resin matrix. By creating a thin layer on the surface of the fiberglass strands, the sizing agent acts as a bridge between the hydrophilic glass fibers and the hydrophobic resin. This layer enhances the wetting and adhesion properties of the fiberglass, promoting better bonding with the resin.
The choice of sizing agent depends on the specific resin system being utilized. Different types of sizing agents can be employed to optimize adhesion with polyester, epoxy, or vinyl ester resins. Moreover, the sizing agent can be customized to offer additional advantages, such as improved impact resistance, UV stability, or heat resistance.
If the fiberglass chopped strand is not adequately surface treated, the adhesion between the strands and the resin may be compromised. Inadequate wetting of the fibers by the resin can result in weak interfacial bonding, leading to delamination or reduced mechanical properties in the final composite product.
In summary, the surface treatment of fiberglass chopped strand plays a vital role in enhancing its adhesion to resin. It enhances the wetting and bonding properties, ensuring the creation of a robust and long-lasting composite material.

In summary, the surface treatment of fiberglass chopped strand plays a crucial role in enhancing its adhesion to resin. It improves the wetting and bonding properties, ensuring a strong and durable composite material.
The surface treatment of fiberglass chopped strand significantly affects its adhesion to resin. The treatment modifies the surface of the strands, creating a chemical bond between the strands and the resin. This improves the overall adhesion and bonding strength between the fiberglass and the resin matrix, resulting in enhanced mechanical properties and durability of the composite material.
