Impregnation or infusion is a common method for incorporating fiberglass chopped strand into a composite material. This process involves mixing the chopped strand with a resin, often a thermosetting resin like polyester or epoxy, to form a matrix material. The resin acts as a binding agent, holding the fibers together and providing strength and rigidity to the composite.
During impregnation, the chopped strand is evenly dispersed in the resin to ensure full coating and saturation of the fibers. This is typically achieved by mechanically agitating the mixture, such as using a mixer or blender, to ensure a uniform distribution of the fibers throughout the resin.
Once the chopped strand is fully impregnated with the resin, the composite material can undergo further processing. It can be shaped into various forms such as sheets, panels, or molded into specific geometries. The material is then cured or hardened, typically through the application of heat or a catalyst, to solidify the resin and create a durable composite structure.
The incorporation of fiberglass chopped strand into a composite material offers several advantages. The fibers provide excellent strength and stiffness, thereby enhancing the overall mechanical properties of the composite. They also improve impact resistance, dimensional stability, and resistance to corrosion and weathering.
Moreover, the chopped strand reinforces the composite, making it more resistant to cracking and delamination. The fibers also aid in the efficient distribution and dissipation of loads, resulting in a more reliable and durable composite material.
In conclusion, incorporating fiberglass chopped strand into a composite material is a crucial step in the manufacturing process as it significantly enhances the mechanical properties and performance of the final product.

Fiberglass chopped strand is incorporated into a composite material by mixing it with a resin matrix, typically epoxy or polyester, and then forming it into the desired shape or applying it as a layer onto a mold or substrate. The chopped strands, which are small lengths of fiberglass fibers, add strength, stiffness, and reinforcement to the composite, improving its overall performance and durability.
