Fibreglass is a hugely lucrative and in-demand material that is used by multiple industries for countless products. But why is it so popular, what are its specific advantages and why should you consider it when choosing an everyday item, like an umbrella?
Fibreglass also goes by the name ‘glass reinforced plastic’ (GRP) and is created by joining a collection of very thin fibres of glass with a binding solution. The main ingredients of fibreglass are silica sand, soda ash and limestone. Each glass fibre is often flattened into a sheet and can be constructed from various types of glass, and after, the fibreglass can be molded into multiple shapes while not compromising its strength and durability.
The use of fibreglass began in World War II, after glass fibres (invented by Russel Games Slaytor) and polyester resin (used since 1935) were combined to create an ultra-strong, long-lasting product. Fibreglass was an excellent alternative to metal during wartime and currently, two million tons of unsaturated polyester resin is produced across the globe.
Due to its malleability and tenacity, fibreglass is used across a wide variety of industries to make everything from kayaks and ladders, to bathtubs and circuit boards - and of course, the humble umbrella.
Beneficial properties of fibreglass
Fibreglass is an extremely versatile material which allows it to benefit multiple manufacturing sectors. But what are the main advantages of this popular material?
- It’s non-rotting and won’t corrode
- It’s an excellent thermal conductor, and electrical insulator
- It’s exceptionally strong with a resistance that is better than steel.
- It has high slip & high impact resistance
- Easily combines with other synthetic resins.
- Holds its shape and won’t expand or contract with heat/cold easily.
Fibreglass is commonly used by a variety of sectors. It’s popularity is down to its range of abilities, with fibreglass offering unparalleled longevity, versatility and safety, but also provides high thermal insulation. This makes it one of the preferred materials for industrial gaskets, which means it’s used in machinery employed by multiple industries, including aviation, motoring, electronics and housing. So… if it’s used to underpin the bricks and mortar of our homes, those are mighty credentials for the everyday brolly.
Benefits of fibreglass umbrellas
It’s clear that fibreglass offers many manufacturing advantages. But how are these relevant to protecting you from wind, rain and stormy weather?
Durability
If you want an umbrella that will last, fibreglass offers excellent longevity. Fibreglass is tougher than carbon fibre, as it has a higher breaking point when flexed, as well as the ability to bend without compromising its structure. Since it’s incredibly difficult to break fibreglass and it has such a high resistance to impact, an umbrella should last you a long time - no matter how often it’s used or where you store it.
Being non-conductive, fibreglass doesn’t absorb moisture and, unlike steel and aluminium, fibreglass won’t corrode. This means you can use it in heavy downpours or in places with high salt content in the air without worrying that you’ll have to replace it.
Tenacity
Pound for pound, fibreglass is tougher than sheet metal, which is why it’s used for products such as wind turbines and car bodies. If you’ve ever experienced the super-embarrassing phenomenon of your brolly flipping inside out on you in the wind, you’ll definitely appreciate some super strong fibreglass under that canopy!
