Cardboard research at the TU Delft is performed by 4 researchers, who divide their interest between, fundamental research, technology development and application designs. However these domains have strong relationships and need one another in order to become effective. The research in cardboard has 8 or 9 different aspects to cover all relevant aspects in architecture. The approach at the TU Delft is methodical; one of these methods is based on the development of new products and could give a proper lead to efficient product development, even in new territories. At the end a number of 12 different questions are posed on aspects that matter in fundamental research; 14 on development questions and another 14 on design questions. With these 42 questions research could be efficient and permanent for the coming 5 years. The industry should respond to these questions by selection and support. If not, the TU Delft has its own preferences.
