What manufacturing defects commonly occur in composite material outdoor bar stools?

Composite material outdoor bar stools are popular for their durability and weather resistance, but they can still suffer from manufacturing defects. Common issues include delamination, where layers separate due to poor bonding, and surface cracks caused by improper curing or UV exposure. Weak joints or uneven resin distribution may lead to structural instability, while air bubbles trapped during molding can weaken the material. Additionally, color fading or uneven pigmentation often occurs due to low-quality additives or insufficient UV protection. Identifying these defects early helps ensure the longevity and safety of your outdoor furniture.
