Summary

Wood chip plastic composites (WCPC) with high mechanical properties were produced by combining long pine wood strands with formaldehyde-free binder systems. The obtained novel bio-based lightweight materials compensate major disadvantages of commonly used oriented strand board (OSB). WCPC are load- and application-optimized, non-toxic, with zero-waste and cost-efficient. Suitable binder systems and production process options for WCPC were selected. The behavior of strands when pressurized was investigated to specify the limit of the compression pressure, that did not cause damage of the wood cell walls. Specimens were produced with an experimental mold using thermoplastic as well as thermosetting binder systems and resin injection as well as hot compression molding techniques. Mechanical properties of WCPC were determined and compared with the properties of conventional wood-based materials.
