Base materials
The choice of components for a fibre-plastic composite, i.e. the reinforcing fibres and the matrix in which they are embedded, in conjunction with the manufacturing techniques, determine the properties of the composite. However, in contrast to many other materials which can be purchased from manufacturers as semi-finished goods or prepared to standards, the optimum parameters of a fibre-plastic composite are only achieved through the interaction of the right technology and the trained, experienced personnel in the design and production departments.
Hahlbrock processes almost all types of fibrous materials based on glass, carbon, and aramid. Fine-tuned to the target functionality, technical environment, and economical criteria every shaped mould is made up of specifically confectioned fibres and thermosetting plastics (unsaturated polyester resins, epoxy resins, or vinylester resins) to create a specific light-weight und high-strength product. Usually, the prehardened shaped moulds are thermally post-treated (annealing) according to the resin producers' specifications.
Besides the traditional properties of the fibre-plastic composite, e.g. its low weight combined with high strength, good corrosion resistance and excellent mouldability, it is also possible to generate further advantageous material properties. Over many years we have built up a climate of trust with our resin suppliers which enables us to make use of a multitude of special formulations of standard resins and to test these on our premises for their suitability for specific projects. This has led to resins being developed for demanding manufacturing techniques and to new applications, e.g. in building, being opened up thanks to better translucency, elasticity or fire resistance (HALUSITE®).
