Benefits of Utilizing Sandwich Burner in Wind Turbine Blades A sandwich heating element is an electrically conductive fibre arranged in a polycarbonate matrix material layer as an internal warm source. This enables the heat to be produced from a single factor as well as can consequently minimize the melting time and/or the temperature at which the polycarbonate matrix product layer is melted since the warm is not transferred to the external parts of the laminate framework by means of the sandwich core material. Making use of a polycarbonate matrix product, for instance an ABS polymer, with interior burner serves to generate laminate structures for wind generator blades. The burner are comprised of carbon fibres, steel fibers or glass or plastic fibres covered with an electrically conductive layer. The burner can be given at picked locations of the thermoplastic matrix product layer and are made use of for a fast warming up of the thermoplastic matrix material to enhance the bonding of the upper as well as lower laminate parts or layers, along with of the sandwich core product, to each other. Because of this, the sandwich laminate is a lot more reliable and also, therefore, less likely to damage. As an additional advantage, the sandwich laminate is much more recyclable and also, consequently, cheaper. This is due to the fact that the sandwich laminate, by avoiding the typical external heating of the mould, can be constructed from lighter products with excellent thermally protecting properties. This is especially important for the manufacture of wind turbine blades where a light-weight building is a priority, e.g. a foamed polymer or a honeycomb framework, and where the weight of the sandwich laminate is not too high. Another advantage of utilizing the sandwich laminate is that the temperature of the inner layers, specifically of the polycarbonate matrix material layers, is able to be controlled through a thermostat to stop getting too hot. This is especially crucial for the manufacturing of big frameworks such as the interior parts of wind generator blades where an overheating of the framework can result in a decrease of the blades turning. Additionally, the heating elements can be placed in such a way that a greater quantity of warm is introduced at those places where it is most needed to heat up the polycarbonate matrix material. This is specifically useful for wind generator blades due to the fact that the polycarbonate matrix material must be warmed up to a temperature level of regarding 100 ? C to thaw and combine with the reinforcement fibers, which can just be done if the temperature level is over the melting factor of the thermoplastic matrix material. For this objective the inner heating elements of the sandwich laminate can be provided with present by a matching number of electrically conductive fibres made up of carbon fibres, metal fibers, or glass or plastic fibers, or by a mix thereof. These fibers are set up at selected factors in the thermoplastic matrix material layer and also can be placed to be near to each other. Additionally, the burner can be positioned at a distance from each other and also gotten in touch with each various other by means of electrical link flows of the sandwich core material. These passages might be sewed into selected components of the shielding sandwich core product or otherwise prepared beforehand. This is preferably done by utilizing copper threads as the conductive strings, although various other, ideally extra affordable options might be made use of.
