Definitions

Brain-drain: Loss of knowledge due to emigration of trained personnel.
Composites: hybrid materials made of a polymer resin reinforced by fibres, combining the high mechanical and physical performance of the fibres and the appearance, bonding and physical properties of polymers.
Consolidation: Packing and freezing into a solid state of the fibres and matrix by pressing out the remaining air.
Dehusking: Mechanical removal of the fibre layer from the coconut.
Durability: The amount of time during which a material or product functions properly.
Filament winding: Process in which products are made by winding fibres around a rotating mandrel.
Geo-textile: A fabric, which is draped over the soil to prevent erosion due to wind or water.
Hackling: Combing of the fibres for removal of the wooden remains and isolation of the clean fibre.
Hot press methods: Manufacturing technique in which fibres and a matrix are placed in a mould, upon which applied pressure in combination with raised temperature result in the desired product shape.
Impregnating: Wetting fibres with a polymer matrix.
Laminae: A composite consisting of a single fibre-layer.
Laminate: A composite built up out of multiple fibre-layers.
MLSE: Medium and Large Scale Enterprises (>20 personnel)
Natural fibre composite: A composite based on natural fibres.
Polymer dispersion (latex) Mixture of finely divided solid particles in a fluid.
Polymer matrix: Material consisting of molecules with a long chain-length, supposed to surround fibres in a composite material.
Prepreg: A composite semi-finished material, which can be shaped and further consolidated upon heating.
Pultrusion: Continuous production process in which a mixture of fibres and matrix is pulled through a hole with the cross-sectional shape of desired product. Profiles at any length can be manufactured.
Resin Transfer Moulding: Manufacturing technique in which the matrix is pressed or sucked through the dry fibres to form a composite.
Retting: The rotting process to remove the fibres from the rest of the plant.
Sandwich structure: Structure consisting of two stiff skins separated by a core material.
Single step manufacturing: Manufacturing of a complete construction in one handling. In contrast to manufacturing of multiple parts, which need to be assembled to form the final construction.
Specific Stiffness: Strength per unit weight.
Specific strength: Strength per unit weight.
SSCE: Small Scale and Cottage Enterprises (<20 personnel)
Sustainability: The amount of "reduced impact" on the environment during the entire lifetime of a product.
Trinity essence: The integrated design process consisting of concepts, materials and processes. Integration is required to fully use the advantages of composites.
Vacuum forming: Manufacturing technique in which the atmospheric pressure is used to form a laminate.
