A fibre composite is a material (matrix) in which fibres of a different material are embedded. This can for example serve the purpose of achieving a higher dimensional or temperature stability. Usually, however, it is intended to generate a higher rigidity or stiffness.
Very often, the matrix is a plastic, but metals or ceramics are used as well. Glass fibres and carbon fibres are the most commonly used reinforcement fibres, but aramid, polyethylene, and natural fibres are found as well.
The term ‘fibre composite’ is often abbreviated to ‘composite’, which is also understood to refer to advanced composites. bzw. Advanced Composites verwendet. To improve the quality of a composite, the reinforcement fibres can be plasma-treated before impregnation with the matrix, in particular by activation or coating, to improve the adhesion to the plastic matrix.
