FRP Composites Steel Aluminium Wood
Corrosion Resistance Resists chemicals & Insect damage Subject to oxidation & Corrosion Can cause galvanic corrosion Can rot & decay when exposed to moisture, water & Chemicals
Density (g/cm3) 1.9-2.1 7.85 2.7-2.8 0.3-0.7
Electrical Conductivity Non-conductive Conducts electricity Conducts electricity Can be conductive when wet
Thermal conductivity Good insulator with low thermal conductivity Conducts heat Conducts heat Low thermal conductivity
Impact resistance Will not permanently deform under impact Can permanently deform under impact Easily deforms under impact Can permanently deform or break under impact
Cost Lower installation & maintenance cost and longer product life allow for a lower life cycle cost High life cycle cost Comparable price to FRP Wood is cheaper but also much more susceptible to degradation, causing higher maintenance costs lifecycle cost
EMI/RFI Transparency Transparent to radio waves & EMI/RFI transmissions Can interfere with EMI/RFI Transmissions Highly reflective to EMI/RFI Transmissions Transparent
Fabrication Because of low weight, FRP allows for considerable flexibility in terms of design. No welding are required Require welding. heavier material requires special equipment to erect & Install Good machinability Can be field-fabricated using simple carpenter’s tools
