The performance of chopped strand can be significantly affected by its ability to absorb moisture. Chopped strand is typically composed of glass fibers that have been cut into shorter lengths. These fibers are commonly used as reinforcement material in various composite applications, including plastics, concrete, and fiberglass.
When moisture is absorbed by chopped strand, it can have a negative impact on its mechanical properties. The moisture can degrade the integrity of the glass fibers, causing them to weaken and become brittle. As a result, the composite material may experience a loss of tensile strength, stiffness, and overall durability.
In addition, the presence of moisture in chopped strand can also result in dimensional instability. As the fibers absorb water, they may expand, leading to swelling or warping of the composite material. This can affect the accuracy and stability of the final product, making it unsuitable for applications that require precise measurements or tight tolerances.
Moreover, the absorption of moisture can create an environment conducive to the growth of microorganisms, such as mold or bacteria, within the composite material. This can compromise the structural integrity of the material and lead to degradation over time.
To address these issues, manufacturers often take measures to minimize the moisture absorption in chopped strand. This can involve the application of surface treatments or coatings to make the fibers more hydrophobic, or the incorporation of moisture-resistant additives into the composite matrix. Proper handling, storage, and transportation practices are also crucial in preventing moisture absorption in chopped strand.
In conclusion, the moisture absorption of chopped strand is a critical factor that significantly impacts its performance. It can lead to reduced mechanical properties, dimensional instability, and potential degradation due to microbial growth. Therefore, it is important to consider the moisture resistance and management of chopped strand when selecting and using it in composite applications.

The moisture absorption of chopped strand can significantly affect its performance. When moisture is absorbed, it can weaken the mechanical properties of the material, such as its tensile strength and stiffness. Moisture can also lead to dimensional changes, causing warping or distortion in the final product. Additionally, moisture can have a negative impact on the bonding between the chopped strand and the resin matrix, reducing the overall strength and integrity of the composite. Therefore, controlling and minimizing moisture absorption is crucial in order to maintain the desired performance characteristics of chopped strand.
