The performance of fiberglass chopped strand relies heavily on its fiber surface treatment. This treatment involves the application of a chemical coating or sizing to enhance the properties of the strands and their compatibility with the matrix material.
One of the main benefits of fiber surface treatment is the enhancement of adhesion between the fiberglass strands and the resin matrix. By modifying the surface chemistry of the fibers, the treatment increases their reactivity and promotes better wetting and bonding with the resin. This improved adhesion allows for the transfer of stress from the matrix to the fibers, resulting in increased strength and stiffness of the composite material.
The surface treatment also has a significant impact on the fiber-matrix interface. It can create a mechanical interlock between the fibers and the matrix, strengthening the bond and preventing fiber pull-out or debonding. This contributes to improved impact resistance and durability of the composite.
Additionally, the surface treatment affects the moisture resistance of fiberglass chopped strand. It can make the fibers more hydrophobic, reducing water absorption and improving dimensional stability. This is particularly important in applications where exposure to moisture or harsh environmental conditions is a concern, as it helps maintain the mechanical properties of the composite over time.
Moreover, the surface treatment influences the dispersibility and flowability of the chopped strands during processing. It reduces the tendency for fiber clumping or agglomeration, ensuring a more uniform distribution of fibers within the matrix. This leads to improved mechanical and thermal properties of the composite.
In conclusion, the fiber surface treatment of fiberglass chopped strand has a significant impact on its performance. It enhances adhesion, improves the fiber-matrix interface, increases moisture resistance, and promotes better fiber dispersibility. These effects ultimately result in improved strength, stiffness, impact resistance, durability, and dimensional stability of the composite material.
