FRP (GRP) Foam Core Sandwich Panel

FRP (fiberglass reinforced plastic) foam core sandwich panel, also known as GRP (glass reinforced plastic) foam core sandwich panel, are a popular choice for a wide range of applications due to their strength, durability, thermal insulation and lightweight design. This panel is made by sandwiching a foam core between two layers of FRP or GRP sheets.

What types of FRP (GRP) are used for producing Foam Core Sandwich Panel?

There are several types of FRP and GRP sheets available for use in FRP sandwich panel. These sheets can be made from a variety of materials, including fiberglass, carbon fiber, and aramid fibers. Each of these materials has its own unique properties and benefits, and the best choice will depend on the specific needs and requirements of the project. And in our factory, we mainly produce with the type of fiberglass.

Fiberglass reinforced plastic (FRP) sheets are made from strands of fiberglass that are impregnated with a resin. These sheets are strong and durable, and are resistant to weathering, corrosion, and other types of damage. They are also lightweight and easy to work with, making them a popular choice for a wide range of applications. And FRP sheets surface can be smooth or pebbled; Color wise, they can be white, grey, black, yellow, blue etc; Gloss rate wise, they can be matt or high glossy. And the fiber types can be chopped fiber or woven roving.

What types of Foam cores available in FRP (GRP) Foam Core Sandwich Panel:

There are several types of foam cores available for use in foam core sandwich panel. This foam cores can be made from a variety of materials, including polyurethane (PU), polystyrene (XPS), and EPS. Each of these materials has its own unique properties and benefits, and the best choice will depend on the specific needs and requirements of the project.

Polyurethane foam cores (PU foam) are strong and durable, and are resistant to weathering, corrosion, and other types of damage. It has best thermal insulation rate out of the 3 types, and it can also be made into fire retardant grade upon request.

Polystyrene foam cores (XPS)are also strong and durable, and are resistant to weathering, corrosion, and other types of damage like PU foam. It’s slightly cheaper than PU, but has similar thermal insulation property and low water absorption.

EPS foam cores are cheapest option out of the three types. It has reasonable thermal insulation property, also lightweight. For general using that is not very high requirements, EPS foam core is a nice option.

Applications of FRP (GRP) Foam Core Sandwich Panel:

GRP foam sandwich panel is used in a wide range of applications, including building construction, transportation, and recreational vehicles. It is lightweight and easy to work with, making them a convenient and cost-effective choice for a wide range of applications.

In building construction, GRP sandwich panel can be used as wall panel, roof panel, floor panel, and more. This panel can provide a strong and durable structure that is resistant to weathering, corrosion, and other types of damage. They are also lightweight and easy to work with, making them a convenient and cost-effective choice for a wide range of building construction projects.

In transportation, FRP foam core panel can be used as body panel, door panel, and more. This panel can provide a strong and durable structure that is resistant to weathering, corrosion, and other types of damage. They are also lightweight and easy to work with, making them a convenient and cost-effective choice for a wide range of transportation applications.

In recreational vehicles, FRP sandwich panel can be used as body panel, roof panel, and more. This panel can provide a strong and durable structure that is resistant to weathering, corrosion, and other types of damage. They are also lightweight and easy to work with, making them a convenient and cost-effective choice for a wide range of recreational vehicle applications.

Key Benefits of FRP (GRP) Foam Core Sandwich Panel:

One of the main benefits of using GRP sandwich panel is their strength-to-weight ratio. This panel is much stronger than other materials of the same weight, such as aluminium or steel, making them a good choice for applications where weight is a concern. This strength-to-weight ratio also makes This panel suitable for use in structures that are subject to high loads or stresses, such as bridges, cranes, and other heavy-duty applications.

In addition to their strength-to-weight ratio, GRP sandwich also offer a number of other benefits. This panel is resistant to UV, chemical corrosion, and not easy to dent or break, making them a good choice for use in outdoor or exposed applications.

FRP sandwich panel can also be made resistant to fire, making them a good choice for use in buildings and other structures where fire safety is a concern.

Overall, the versatility of FRP (GRP) foam core sandwich panel makes them a popular choice for a wide range of applications. Whether you are looking for a strong and durable panel for building construction, transportation, or recreational vehicles, this panel is a great choice.
