Plastic composites are materials made by combining plastic with other substances, such as fibers or fillers, to enhance their properties. This combination results in a lightweight, strong, and durable material that can be used in various applications, from automotive parts to construction materials. These composites can be tailored to meet specific needs, such as increased strength, flexibility, or resistance to environmental factors. Common types of plastic composites include fiber-reinforced plastics and wood-plastic composites, which are often used in furniture and decking. Their versatility makes them popular in many industries.
