PROPERTYFRP COMPOSITESSTEELALUMINIUM
CORROSION RESISTANCEResists a broad range of chemicals and unaffected by waterSubject to oxidation and corrosion which otherwise requires galvanisation for many complications – a expensive and difficult process. Can cause galvanic corrosion
STRENGTHGram for Gram stronger than Steel and aluminium
Compressive strength – 206.5MPa (LW)
Flexural Strength – 206.5MPa (LW)
Yield Strength – 248.22MPa
Higher tensile strength and higher tensile modulus
Yield Strength – 241.325MPa
Higher tensile strength and higher tensile modulus
WEIGHTWeights 25% of steels and 70% of aluminiumDue to high weight often requires lifting apparatus where it would not be require for FRP, lowering costs33% of the weight of steel
ELECTRICAL CONDUCTIVITYNon conductiveRequires grounding due to high conductivity Requires grounding due to high conductivity
THERMAL CONDUCTIVITYGood insulator with low thermal conductivity
0.04W/mK
Low thermal coefficient of expansion
12.6 – 14.4 m/m/C *10^-6
Thermal conductivity
50.2 W/m
Low thermal coefficient of expansion
13.5 – 14.4 m/m/C *10^-6 K
thermal conductivity
25W/mK
Low thermal coefficient of expansion
23.4 m/m/C *10^-6 K
IMPACT RESISTANCEWill not permanently deform under impactCan permanently deformCan permanently Deform
COSTLower installation costs, less maintenance, longer product life cause lower lifespan costLower initial material costsPart Price comparable to FRP
MANUFACTURE AND FABRICATIONCan be easily manufactured, easy of complex shapes, can be fabricated with simple carpenters tools. No torches or torches required
Often requires welding and cutting tools, with heavy equipment requiring special processes.
Good machinability
