From Parquet Floors to Structural Wood Components for Vehicle Construction

Weitzer Parkett is a family-owned traditional company with core competencies in the manufacturing of high-quality parquet floors and refinement of their surfaces. With increasing globalization and the challenging price war, Weitzer Parkett has decided to focus on the development of further economic pillars, and against the trend of outsourcing production sites to low-wage countries.

To advance these development projects with a scientifically based approach, the company decided to purchase a universal testing machine from ZwickRoell. Since then, the ProLine 10 kN has been used at the site in Weiz, Austria for the design of various wood composite components and the technical analysis of the effectiveness of wood modifications. Due to the ProLine’s wide variety of application possibilities, the testing machine is ideal for the various needs at Weitzer Parkett. All current and future test requirements can be easily met with the ProLine. With its participation in the WoodC.A.R. project, Weitzer Parkett wants to meet the high demands of the automotive industry and qualify as a supplier of structural wood components for automobile manufacturing. One of the essential requirements for a material to be accepted in the automotive industry is the ability to simulate accidents and extreme situations using FEM (finite element methods). Due to the inhomogeneity and anisotropy of wood, such methods have not yet been considered in traditional applications and have failed based on the available material characteristics. To increase the homogeneity, irregularities such as knots, resin pockets and other wood characteristics are evenly distributed over the component through the development of special fiber and layered composite materials, making it possible to calculate them statistically. With the ProLine, Weitzer Parkett can now determine the material characteristics of individual components as well as the new complete structures within different test arrangements such as 3-/4-point flexure test, tensile and compression test, shear test, and so on, all within the context of the research project. With the determined characteristic values, new layered composites and entire components can be developed and the simulation checked in real testing scenarios. The knowledge gained will subsequently be applied to series production and incorporated into quality assurance planning. For the standard product range for example, a special test arrangement was developed using the ProLine in order to measure not only the rise of the arch but also the resulting deformation force. As a result, Weitzer Parkett is now able to precisely measure the influence of minimal changes in design and production technology and uses this information for ongoing development and optimization.

In addition to these very scientific applications in various research projects, the ProLine has already found application in quality control of ongoing production and incoming goods inspection:

  • Tensile strength perpendicular to the plane of the board DIN EN 319
  • Tensile shear strength ÖNORM EN 302-1
  • Indentation resistance ÖNORM EN 1534
