The following can be considered as the ‘standard’ properties typically exhibited by an FRP composites component.
• High strength at low weight
• Ability to tailor properties to meet wide-ranging performance specifications
• Moulding to close dimensional tolerances, with their retention under in-service conditions
• Good impact, compression, fatigue and electrical properties
• Ability to markedly reduce part assembly
• Excellent environmental resistance
• Ability to fabricate massive one-piece mouldings
• Proven in-service track record
• Low-to-moderate tooling costs
• Cost-effective manufacturing processes
• Ability to build in, ex-mould, both colour and texture
• Excellent chemical and corrosion resistance
• High ultra-violet radiation stability
• Good-to-excellent fire hardness
• Good structural integrity
• Good thermal insulation
• Ability to attenuate sound
• Respectable abrasion resistance
• Ready bonding to dissimilar materials
• Medium-to-high productivity rates
Properties of FRP’s That Can be Improved
The following additional properties can readily be provided by reinforcement and/or matrix alteration, chemical addition or other formulation, material, or fabrication alteration.
• Excellent chemical and corrosion resistance
• High ultra-violet radiation stability
• Good-to-excellent fire hardness
• Good structural integrity
• Good thermal insulation
• Ability to attenuate sound
• Respectable abrasion resistance
• Ready bonding to dissimilar materials
• Medium-to-high productivity rates
