Answer: (Explanation of any three properties= 3 marks) Properties of GRP( Glass Reinforced Plastic)/CRP ( Carbon Reinforced : Plastic)

1.High corrosion resistance: Offering exceptional corrosion resistance, GRP/CRP is highly tolerant of the most aggressive of environments. Its total resistance against chloride ion attacks demonstrates its durable nature and ability to withstand harsh conditions. Unlike traditional alternatives, such as steel, aluminium and timber, GRP/CRP delivers a long-term practical solution that overcomes the inherent corrosion challenges facing industry today.

2.High strength GRP/CRP’s superior tensile strength is equal to or greater than equivalent steel profiles. Despite its lightweight properties, GRP/CRP offers impressive strength-to- weight load-bearing performance. The high glass-to-resin ratios used in our technically advanced formulation ensure our GRP/CRP products outperform and outlast traditional materials.

3.Lightweight 75% lighter than steel equivalents, GRP/CRP significantly reduces transport costs and eliminates the need for heavy lifting equipment. As it can be easily cut and manoeuvred onsite, the risk of manual handling injuries is mitigated.

4.Non-conductive, inert and non-sparking The non-conductive properties of GRP/CRP make it ideally suited for use on electrically hazardous sites. A highly effective electromagnetic and thermal insulator, it is electronically transparent and not affected by electromagnetic fields or radio wave frequencies. The non-sparking qualities of GRP/CRP make it suitable for locations where combustible gases may be present.

5.High impact resistance GRP/CRP resists sudden and severe point loading and avoids permanent distortion. If the GRP/CRP is deformed due to impact, it will return to its original shape without contractors having to incur costly repairs or replacements.

6.Easy to fabricate GRP/CRP can be easily fabricated and cut onsite to accommodate precise specifications and complex layouts. Using standard hand tools, such as circular saws, contractors can easily cut the product without compromising any of its advantageous properties.

7.Low maintenance GRP/CRP is an incredibly resilient and durable material that delivers outstanding cost benefits. GRP/CRP, in all its forms, offers a low maintenance solution with little need for renovation or refurbishment during its fifty year lifespan.
