Název v původním jazyce

Surface soundness of basalt fibre reinforced polyvinyl acetate plywood coating

Popis výsledku v původním jazyce

Basalt fibres have become popular reinforcement of polymers due to their environmentally friendly properties. These properties constitute the basis for the enhancement of materials such as wood or WBP (wood-based panels). Other polymers than those commonly used for FRP (fibre reinforced polymers) may be applied. PVAC (Polyvinyl acetate) adhesive seem to be a promising choice as it safer substance. However basalt fibres do not create sufficient bond with many adhesives. In this study; bond strength of one polymeric emulsion adhesive, two PVAC adhesives, and one layer of basalt fabric and birch plywood were evaluated. Finally, the surface soundness of the best Ponal Super 3 with different amounts and one or two layers of basalt fabric were investigated. Surface layer was well bonded and failures were always located in the wood. Statistically evaluated data were not significantly different, proving that several layers of basalt fabrics can be bonded together, while variable amounts of adhesive do not affect the surface soundness of this reinforcing layer.
