Some of the most commonly used and lowest cost cores are any of the several light woods. The most popular is Balsa, but substantial use has also been made of Spruce, Western Red Cedar and many others.
The structural sandwich is generic name for a group of materials in which we build the composite using a thick, low density core material, faced on both surfaces with a thin, high-strength skin, or facing. The sandwich has to have a very strong and rigid bond which holds the facings in good contact with the […]
Aromatic polyamides (polyparaphenylene terephthalamide) as reinforcing fibres are characterised by very high tensile strength and modulus, low density and good heat resistance. In composite form they outperform glass fibres on these properties when compared on an equal volume-fraction-of-reinforcement basis. Compressive strength, however, is much lower for aramid reinforced composites. Machining (sawing, drilling, grinding) of aramid […]
Carbon fibres are produced by thermal decomposition (pyrolysis) of organic fibre materials. Starting materials for the production of carbon fibres are organic fibre materials. These precursor yarns are either rayon or polyacrylonitrile (PAN). PAN has a higher carbon yield and is easier to transfer into a high grade carbon fibre.
The name “glass” refers to a group of materials which are basically undercooled liquids. Glass consists of various oxides which melt to form eutectics. When the molten glass is quickly cooled to room temperature it will turn into a clear rigid solid. This glassy state, unlike the solid state and the fluid state is not […]
Aerontec was formed in order to be a distributor of composite materials and technology here in South Africa. The company was started in February 2002.
Aerontec is situated in Claremont, Cape Town, with a door-to-door road service to anywhere in South Africa.
“Composite” is a general term meaning an assembly of various and or dissimilar materials used in conjunction with each other to enable them to do a job or task that the individual materials cannot do by themselves. Reinforced concrete is a composite. Wood is a composite.
