Explanation of some technical terms present in the descriptions.
Fibre-reinforced heat cured synthetic material (composite)
Synthetic resin with net structure, into which, in its liquid state, glass, carbon or aramide fibre is inserted, and in the presence of a catalyser it is cured by means of chemical reactions. After curing it cannot be formed without shaping by machine tool, e.g. by heat.
Physical visualisation of the planned or imagined form, usually a positive model. Its form must be identical with that of the intended ready made product.
Model made based on the primary pattern, (its „inverse”), used for manufacturing the product.
Matrix /Shell-mould/ Cup
In the closed-mould technology usually the bottom side element.
Punch /Core-mould/ Stamp
In the closed-mould technology usually the top side element.
The process is suitable to produce pieces of any size and form; the layers of the reinforcing material are placed manually into the prepared mould (model), then they are (impregnated) with resin; the resulting laminate is cured without application of pressure.
Resin Transfer Moulding, international name of closed product manufacturing technologies.
Delivery of liquid resin into the mould cavity, e.g. by pressure, closed (RTM) process.
Computer controlled, programmed shaping.
High performance, PC supported 3 dimension parametric modelling, engineering, designing program.
The most widespread reinforcing material, due to its low price and high strength.
High-resistant and high-modulus reinforcing material made of organic carbon compounds through pyrolitic process.
Aromatic polyamide or aramide fibres are, similarly to fibreglass and carbon fibres, belong to the family of high-performance fibres. Their main characteristics, which explain their use more and more, are good heat-stability, good resistance against chemicals, high strength and elasticity modulus.
5-6 cm long staples prepared from filaments with a diameter of about 10 microns, pressed in disorder one over and alongside another by 50-60 pieces, with adhesive. It has soft touch, with textile-effect.
The same as the previous one, but the staples contain more filaments, are of unlimited length, spinnable, similarly to the spinning yarn, the pre-plait is processed into glass-cloth by a textile machine.
