Pultruded Fiberglass FRP Embed Angle

1.Introduction

1)FRP products are with low weight and high strength .Density: 1.5-2, 1/4 of carbon steel, but the same tensile strength with carbon steel. So the FRP products can be widely used in aerospace, rockets, high-pressure container, and so on.

2)Great decay resistance

FRP product has good decay resistance, it has good ability to resist to air, water and general concentration of acid, alkali, salt, and a variety of solvent oil. So, it also can be used in chemical anticorrosion to replace steel, wood and other mentals.

3) Good electrical performance FRP is a good insulation material, it can keeps good dielectric properties under high frequency.

4)Good microwave permeability, so it is widely used to make radar antenna mask.

5)Good thermal performance.FRP is with low thermal conductivity, in room temperature, its 1.25~1.67kJ/ (m.h.k), is excellent insulation material.

6)Good plasticity;The material can be made into everything according to consumers' request

2.Pultrusion Technique

During the pultrusion process,the raw material are pulled through a heated steel forming die using a continuous pulling device. when the reinforcements are saturated with the resin mixture in the resin bath and the wetted reinforcement package is wrapped in a surfacing veil. the completed package then goes into a performer that roughly forms the package into the appropriate shape to enter the heated die for curing. the die is the exact shape of the final part desired. upon exiting the die, the part is over 90% cured and solid. the length of the part required is pulled through the cutoff saw and the process is complete.

3. Material: FRP,fiberglass

1)reinforcement material:fiberglass, glass mat, continuous strand mat, surfacing mat, needled mat.

2)basis material:unsaturated polyester resin,epoxy resin,vinylester resin  

4.Application of FRP Profile:

1)electrical&electronics markets

2)cable tray,radome,insulation ladder,etc.

3)Chemical anti-corrosion markets

grating floor, handrail, working platform, undergrand pression pipe, stairs,etc.

4)building construction markets,bridge protection closed system,movable house structure,working platform,window frame, window sash and its components,etc
