Ir. Jos Sinke

Head of Delft Aerospace Materials & Structures Laboratory. The laboratory has experience with a wide range of bonding techniques, as well as riveting and other mechanical joining techniques. Extensive knowledge and hardware for chemical pretreatments of the adherents are available.

Numerically controlled milling can be performed for complex shapes, e.g. wind tunnel models (milled aluminium), or moulds for the fabrication of thermoplastic or thermosetting composite components. Composite parts can be formed by: diaphragm forming, deep drawing, vacuum assisted resin transfer moulding, filament winding, rubber press techniques and high temperature techniques.

Any evaluation of new materials or new structural components should include realistic tests with a relevant simulation of actual loading and environment of the structure in service. Experience with requirements and function of structures is available, together with advanced testing methods to simulate realistic loading condition (e.g. flight by flight load history simulation).

Many testing methods are available in the Laboratory: fatigue, with a wide range on fatigue equipment, tensile test, compression test, 3 point bending, 4 points bending, impact tests, stiffness measurement, strain measurement, dynamic characterization of fibre-reinforced composites, heat simulation, material ageing, non destructive testing.
