FRP ROPERTIES:
Lightweight,high strength and easy installing:
1.FRP panel's relative density between 1.5g/cm3 to 2.0g/cm3,only carbon steel 1/4~1/5,but the tensile strength is close,even more than carbon steel,the specific strength can be compared with the high performance alloy steel.Thus,in aviation,rockets,spacecraft,high pressure vessels as well as in other products need to reduce the weight of applications,have excellent results.Some epoxy FRP tensile,bending and compression strength can reach more than 400Mpa.XPS board completely closed-cell foam chemical structure and its honeycomb physical structure, making XPS composite board with light weight, high strength characteristics,easy to cut,transport and not break, easy to install.FRP sandwich panel has extremly high compressive strength and impact strength.compressive strength from 150Kpa to500Kpa according to different thickness board or models.
2.Crossion resistance:
FRP is a good anticorrosive material,it has a better resistance for the atmosphere,water and the general concentration of acid, alkali, salt and a variety of oils or solvents. It has been applied to all aspects of chemical corrosion replacing carbon steel,stainless steel,wood,nonferrous metals and so on.FRP sandwich panel will not age,decomposite,produce harmful substances in long-term use,its chemical properties are extremely stable,its properties will not degradate due to corrosion or water degradation, so that its superior performanceation can maintain in high temperature environment.
3.Good electrical performance:
FRP Is an excellent insulating material used to make insulators.It can protect the good dielectric at high frequency as well.Microwave permeability is good,widely used in radar radome
4.Thermal performance is good:
FRP thermal conductivity is low,room temperature is 1.25 ~ 1.67kJ / (m · h · K), only metal 1/100 ~ 1/1000,is an excellent insulation material.In the case of instantaneous ultra-high temperature it is the ideal thermal protection and ablation materials,can protect the spacecraft withstand high-speed air erosion at 2000ºC or more .FRP sandwich panel core material XPS closed cell rate 99% or more,the formation of vacuum layer to avoid the flow of air and heat transfering,ensured stable insulation properties of the board.
5.Good designability:
It can be designed based on different need to variety of structural products to meet the requirements,the product has a good overall.FRP can be fully selected materials to meet the performance of the product, such as: you can design a product with properties like crossion resistance,resistance to instantaneous high temperature,particularly high strength in one direction, good dielectric and so on.
6.Hydrophoblastic performance:
Polystyrene (XPS)molecular structure itself does not absorb water,FRP sandwich panel core material molecular structure is stable,no gap,solved the material leakage.penetration,frost, condensation and other issues
STORAGE:
The FRP sandwich panel should be stored in a suitable place,preferably at room temperature with 35-65% relative humidity.Avoid the sun, rain and fire.
PACKAGING:
1.in certain size or roll
2.bulk loading in truck or container
