What happens if the resin is not properly mixed before application?

When resin is not properly mixed before application, it can lead to inconsistent properties in the laminate. This inconsistency arises because the chemical reaction that occurs during curing is dependent on the correct ratios and thorough mixing of the resin and hardener. If the components are not adequately combined, certain areas of the laminate may cure differently than others, causing variations in strength, stiffness, and overall performance.

Inconsistent properties can result in weak spots, making the laminate more susceptible to failure under stress. This can jeopardize the integrity of the final composite product, leading to potential safety issues, particularly in marine applications where durability is critical. Ensuring proper mixing is essential for achieving uniform distribution of the curing agent, which is necessary for the laminate to achieve its intended mechanical properties consistently across the entire structure.
