A Timeless Classic: Wood-Water Interaction After Modification with Phenol Urea Formaldehyde Resin.

Wood is an amazing material that breathes and interacts with the water around it. It absorbs water from the air and releases it back, depending on the temperature and humidity. …

Surface energy characteristics of refined fibres at different pressures

Wood fibres were produced on the pilot scale refiner at the BioComposites Centre, Bangor University, from a commercially sourced mix of chipped wood. The fibres were produced at refiner pressure …

Physical properties of UK grown larch subjected to mild and moderate thermal modification processes

Home grown Japanese larch (Larix kaempferi) is a strong attractive species with potential for diversifying softwood timber consumption in the UK. The fast growth rate due to the mild British …

The future of wood composite materials and panel products in the circular economy perspective

The use of timber has a large role to play in the mitigation of climate change and the reduction ofcarbon i n the atmosphere, indeed the growing and use of …

Physical properties and durability of methacrylate impregnated timber

Modifications such as methacrylation of wood can be used to improve both wood mechanical properties and durability characteristics. Samples of pine and spruce wood were impregnated under vacuum with methyl …

How drying conditions can affect resin modified wood

Wood modification with low molecular weight thermosetting resin is a frequently studied technique that is suitable for upscaling1–3. This treatment typically involves separate steps for impregnation, followed by drying, and …

Demonstrating the Suitability of Laser Incision for Timber Treatment Technologies

In any form of wood treatment – preservatives, fire retardants or wood modification  – the uptake of treatment agents is a limiting factor for performance of the finished product. Mechanical …

Wood Modification with Phenol-Formaldehyde-Resin and its Influence on the Dimensional Stability of Homegrown and Imported Hardwoods

It was shown that wood anatomy has a strong influence on WPG, Bulking and Swelling in resin modified wood. The effectiveness of the modification can be expressed by ASE, but …

Mapping fluid flow in wood: the interaction of laser incisions with cell structure

Wood protection, whether by traditional preservatives or using novel treatments relies upon good uptake of fluids. Even technologies such as acetylation, furfurylation, resin modification or bio-based modification agents (e.g. Sor-Ca …

Cell wall diffusion of low molecular weight PUF resin studied by liquid- and solid-state NMR

Wood modification with thermosetting resins is an increasingly popular method aiming to increase the number of applications for readily available plantation timber. Phenol urea formaldehyde (PUF) resin is impregnated into …
