Abstract
A building panel with a high degree of isotropy with regard to the load bearing capacity and flexural strength. The building panel includes a first section and a second section, each section including at least one layer, each of the at least one layer having fibers, whereby the fibers are distributed substantially homogeneously throughout each layer, substantially parallel to the main surfaces of the panel and oriented predominantly in the same direction and the sections are firmly joined in transverse direction, and the first section is thinner than the second section.
Claims15
A building panel comprising:
- a first section and a second section, each section including at least one layer, each of the at least one layer comprising fibers mixed within a binding material;
- the fibers are distributed substantially homogeneously throughout each layer, substantially parallel to the main surfaces of the panel and oriented predominantly in the same direction;
- the first and second sections are firmly joined in transverse direction;
- the first section is thinner than the second section;
- the first section makes up at least 5% of the thickness of the panel and at most 30% of the thickness of the panel;
- the building panel has a fiber content of 5% to 25% by weight;
- the building panel comprises at least 50% by weight cementitious material, and
- the building panel has a degree of isotropy greater than or equal to 0.83 with regard to its load bearing capacity when determining the failure load according to EN 12825 (2001) with the first section beneath the second section.
