SELF- REINFORCED PLASTIC

In self-reinforced plastics, a polymer matrix is reinforced with high-tenacity fibres or tapes of the same polymer family, such as polypropylene-reinforced polypropylene, creating a material with typically 3-5 times the strength and stiffness of the unreinforced polymer, giving the ability to use less material for the same mechanical properties in a component. Additionally, unlike glass or carbon reinforced plastics, self-reinforced plastics are not contaminated with high levels of mineral fibres, so they have the same level of recyclability and density as the base polymer.

 Self-reinforced plastics (SRPs) have enhanced strength and stiffness compared to unreinforced plastics and they have improved recyclability and reduced weight compared to glass fibre-reinforced plastics. They also have outstanding impact energy absorption and the absence of abrasive fibres has advantages in terms of handling and tool wear.

 

Comfil currently produces self-reinforced plastics in form of high-tenacity PET mixed with lowmelting PET (LPET), in form of yarn, fabrics, consolidated plates and rods/tapes. This product range is also known as srPET.
