Strengthening of veneers for 3D-forming. 3D - forming of veneers is used only in limited extent. The reasons are wood properties, mainly anisotropy of wood. In this paper, we propose some chosen methods for strengthening of veneers in directions parallel and perpendicular to the grains, with strengthening means such as hotmelt adhesive and glass fibre with adhesive coating. Properties of modified veneers were compared with the properties of reference - untreated veneers. We compared these properties: strength and deformations - extension in tension, strength and deflection in bending, and 3D - formability. From the results, we can conclude that referred treatments resulted in a slight improvement of 3D - formability.

Wzmacnianie fornirów do formowania 3D. Forniry charakteryzuje ograniczona formowalność. Przyczyną tego są własności drewna, głównie anizotropia. Praca prezentuje wybrane sposoby wzmacniania fornirów w kierunku poprzecznym i prostopadłym do włókien, za pomocą klejów topliwych i samoprzylepnych mat szklanych. Zbadano własności takich wzmocnionych fornirów z fornirami niemodyfikowanymi. Porównano wytrzymałość i elastyczność w rozciąganiu, zginaniu oraz formowalność 3D.
