How to produce FRP XPS sandwich panels and their characteristics and uses

Sandwich panel is a composite material composed of two outer skins and a core material filled in the middle. It is commonly used in construction, transportation, aerospace and other fields. Among them, FRP XPS sandwich panels using two flat FRP Sheets and XPS Foam as core materials have excellent performance and are widely used. This article will introduce how to make FRP XPS sandwich panels, as well as the characteristics and uses of this product.

Steps to make FRP XPS sandwich panels:

Prepare materials: Obtain Flat FRP Sheet and XPS Foam, making sure their dimensions are consistent with the sandwich panel to be made. Generally, a flat FRP sheet with a thickness of 1.5mm or 2mm is used as the surface material. As for the color of the FRP sheet, you can choose it according to your needs. Generally, white or light gray is commonly used. 

Surface treatment: Clean the back side of 2mm or 1.5mm flat FRP sheet and do necessary surface treatment to ensure that the surface is clean and has good adhesion. 

Glue: Apply appropriate glue or resin on the back of flat FRP sheet to bond firmly with XPS foam. 

Lay the XPS foam: Lay the flat FRP coated with glue or resin to the XPS foam board to ensure they fit tightly and eliminate air bubbles. 

Pressing and curing: Put the bonded flat FRP sheet 1.5mm and XPS foam boards into the press for curing to ensure the integrity and stability of the sandwich panel. 

Trimming: After curing is complete, the sandwich panel is trimmed, trimming the edges of FRP sandwich panel to the required dimensions and applying any necessary surface preparation. 

Quality inspection: Carry out quality inspection on the produced FRP XPS sandwich panels to ensure that their surfaces are smooth, free of bubbles, cracks and other defects.

Features of FRP XPS sandwich panels:

Lightweight: XPS foam is light weighted. The combination with FRP sheets makes the sandwich panel lightweight and high-strength. It is suitable for occasions that require light weight and high strength. 

Excellent thermal insulation performance: XPS foam has good thermal insulation properties and can effectively isolate heat conduction, making the sandwich panel excellent in thermal insulation. 

Strong corrosion resistance and weather resistance: The FRP surface has excellent corrosion resistance and weather resistance, giving the FRP XPS sandwich panel a long service life. 

Easy to process: FRP XPS sandwich panels are easy to process and install, and can be cut, drilled, etc. according to specific needs.

Uses of FRP XPS sandwich panels:

Construction field: Used for building exterior walls, roofs, partition walls, cold room wall panels, sound insulation panels, etc. It has good thermal insulation performance and corrosion resistance, and can improve the overall performance and service life of the building. 

Transportation field: Used in manufacturing ship cabin partitions, cold storage truck bodies, etc. Its light weight and high strength make it an ideal material in the transportation field.

As a high-quality composite panel, FRP XPS sandwich panel has wide application prospects and market demand. Through reasonable production technology and quality control, products with stability and reliability can be produced to meet the needs of different fields and promote the development of the industrial and construction fields.
