This hybrid solution provides a 40% weight reduction by replacing the steel crossbeam with a composite
variant. This composite variant is produced using overbraiding to apply dry fibres over a preshaped core
after which the fibres are impregnated using resin transfer moulding. The steel interfaces needed to be
redesigned into a surface-to-surface connection to maintain fibre integrity.

3. ThermopiercingThermoforming Fibre Displacement
Redesign of an arm-rest for a pediatric wheelchair using semi-manufactured com-
posite carbon panels and thermoforming to reduce product weight and production
time. A unique weave was chosen to make it aesthetically more appealing while
providing flexibility for reinforcing the mounting gaps when piercing the holes with
heated pens.

4. Absorbing Honeycomb Base
Functional base concept of a large polymer container
for the transportation of hazardous or valuable liquids.
A honeycomb medium was chosen for its strength in
the vertical direction. It can maintain integrity when
stacked and partially absorb impact when dropped at
an angle.

5. Expanse, office storage
Expanse is a low profile office product, based on injection moulding, designed as an addi-
tion to a work space. The product can slide on to most table surfaces to provide additio-
nal storage. The long Expanse functions as a document holder while the smaller Expanse
can be used to store books, office supplies and accessories.

6. Surface Modeling
A rendered concept of a miniature toy submarine for injection moulding. Based of an existing
concept it consists of 3 parts: the two external hull pieces and internal shell for details.

7. Graphics Design
Left, concept of a hollow alarm clock, based on an
extrusion process, generated in photoshop with
bamboo pen within a 10 hour time frame.
Right, mockup flyers and logo concept for the stu-
dent union Caribische Studenten Vereniging. Poster
and logo requests were occationally accepted from
CSV to help progression and exposure of the union.
