Hardness is a key mechanical property of flooring materials. In this study, the performance veneer floorings (with top layer thickness 0.6 mm) was investigated by dynamic hardness tests, comparing it with those traditional engineered wood 3 and solid floorings. Two hardwoods commonly used on flooring, viz. Quercus robur L. Hymenaea courbaril L., two fast-growing hardwoods, Eucalyptus globulus L...
This research was designed to evaluate surface sampling protocols for use with culture and quantitative PCR (QPCR) amplification assay for detection of the gram-negative bacterial biothreat simulant Erwinia herbicola on a variety of surface materials. Surfaces selected for evaluation were wood laminate, glass and computer monitor screens, metal file cabinets, plastic arena seats, nylon seat cus...
Flooring may play a role in standing fatigue, however previous studies of flooring on subjective and objective measures thought to be related to fatigue/discomfort, have had mixed results. The majority of the differences in the reported results are probably due to differences in procedures and analysis methods, particularly variations in testing duration and exposure time. The impact of floorin...
In this study, acoustic emissions (AEs) were detected through a variety of different flooring materials using a fibre Bragg grating (FBG). The AEs were generated using a low velocity impact test, and by footstep. The acoustic vibrations cause a strain in the optical fibre, and hence alter the wavelength reflected by the FBG. This strain induced wavelength shift can then easily be detected by co...
Wood–plastic composite (WPC) materials are mainly used as flooring in buildings or structural load-bearing plates, and will undergo creep deformation during use, resulting failure safety problems. Therefore, this work adopted the orthogonal test method to carry out tests on wood–plastic composites. We range variance analysis process data analyze influence of load, temperature, relative humidity...
For the sake of improving product quality and economy, a series cold-pressing experiments were carried out to investigate material properties engineered wood flooring with emulsion polymer isocyanate adhesive. Effect pressing time, pressure, adhesive spreading rate on modulus elasticity (MOE) rupture (MOR) was analyzed based orthogonal experimental design. According results, both MOE MOR positi...
