Abstract
Flame retardants and other additives can reduce the performance of adhesives used to produce wood-based panels such as particleboards (PB). Basalt reinforcement was evaluated to compensate for the loss of bending strength to allow the panels to be used in the construction sector. A basalt grid with a grammage of 200 g m−2 was used to reinforce PB containing 15 m% nitrogen-phosphate based flame retardant. The modulus of rupture (MOR) and modulus of elasticity (MOE) of the reinforced panels were higher (69% and 24%, respectively) than those of corresponding reference panels. The thermal analysis revealed that the addition of the flame retardant could result in the PB being upgraded to Euroclass B with a reduced crack formation, as identified via 3D-microscopy. Consequently, the use of basalt grid as a reinforcement material could be a way to reinforce panels that contain strength-reducing additives.
期刊介绍：
European Journal of Wood and Wood Products reports on original research and new developments in the field of wood and wood products and their biological, chemical, physical as well as mechanical and technological properties, processes and uses. Subjects range from roundwood to wood based products, composite materials and structural applications, with related jointing techniques. Moreover, it deals with wood as a chemical raw material, source of energy as well as with inter-disciplinary aspects of environmental assessment and international markets.
European Journal of Wood and Wood Products aims at promoting international scientific communication and transfer of new technologies from research into practice.
