Composites you can find in your home

Examples of composites can be seen everywhere. Let us go through a few examples of composite materials that we come into contact with on a daily basis in our homes.

Fibreglass doors are an excellent example of composites in your home. Composite doors are a great alternative to wood and they are so well made that many people cannot tell the difference. In fact, many fibreglass doors are actually made from molds originally taken from wooden doors. Because composites are extremely strong, these doors are long-lasting, as they would never warp or twist with moisture. They will never rot or corrode, and have excellent insulative properties.

Window frames are another excellent example of the use of GFRP composites. Traditional aluminium window frames have two drawbacks which fibreglass windows improve upon. Aluminium is naturally conductive, but when combined with fibreglass profiles used as window lines, there is improved insulation. 

Another advantage of fibreglass window frames is that the coefficient of expansion of both the glass frame and the glass window is almost exactly the same. This is important because aluminium has a much greater coefficient of expansion than glass. When aluminium window frames expand and contract at a different rate than the glass pane, the seal can be compromised and with it the insulatiory properties.

If your bathtub or shower cubicle is not of porcelain, chances are it is made from fibreglass-reinforced composites. Many bathtubs and cubicles are first gel coated and then reinforced with glass fibre and polyester resin. Usually, bathtubs are manufactured through an open molding process, as a rule either chopped gun roving or layers of chopped strand mat. More recently, FRP bathtubs have been manufactured using the RTM (Resin Transfer Molding) process where positive pressure pushes thermoset resin through a two-sided hard mold.

Hot tubs and spas are other great example of fibre-reinforced composites. Almost all above-ground hot tubs today are reinforced with fibreglass. First, a sheet of acrylic plastic is vacuum-formed in the shape of the hot tub. Then, the back of the sheet is sprayed with chopped fibreglass. Then the ports for jets and drains are drilled out and the plumbing is installed.
