What Is GRP?
GRP or glass-reinforced plastic is a composite material that is both lightweight and strong. It is a highly versatile material that can be used in a wide range of applications across various industries including aerospace, construction, and even residential usage. It is more than likely that you have used a GRP product without even knowing it or may have instead referred to it as fibreglass.
What is GRP Made Up Of?
GRP is a composite material made of polymer matrix and glass fibres. The type of polymer used is dependent on the purpose of the finished product but can consist of polymers such as vinyl ester, epoxy, or polyester thermosetting resin. The glass fibres can be incorporated into the composite material in a variety of ways including being placed randomly, woven into glass cloth, or flattened into a sheet.
How Is GRP Made?
Glass reinforced plastic can be manufactured to achieve the desired properties required for the finished product. During the manufacturing process, the chosen polymer and glass fibres are mixed and molded to create the finished product. Through melting, molding and curing the materials the finished glass reinforced plastic product is created.
What Can GRP Be Used For?
There are seemingly endless uses for glass reinforced plastics. Due to its chemical and corrosive resistant properties, it is often used for water pipes or in settings where PVC is not a suitable choice. Fibreglass or glass reinforced plastic is commonly used to make sports equipment such as kayaks and nets but it is also commonly used in the automotive, aerospace and construction industries. Common uses of glass reinforced plastic include the following.
- Automotive parts
- Airplane parts
- Military equipment
