The vibrational frequency method was used to measure the elastic modulus of laminated veneer lumber (LVL), and the feasibility of using Weibull distribution to analyze the elastic modulus data of LVL was considered. Samples were randomly selected as test pieces at the factory. The sponge support...

Lignin is the most abundant renewable aromatic resource on the planet, and it may be exploited to make the controlled release fertilizers (CRFs) that aid in human sustainable agriculture. Many researches on lignin-based CRFs have been conducted in recent years because of their exceptional...

In order to improve the sound absorption performance of the light-frame timber construction wall, this paper combined the aperture embedded wall unit structure with the actual building wall structure based on the Helmholtz resonance structure principle to design and fabricate two sets of wall...

Oriented strand board(OSB)is a widely used wood material in the construction. The anisotropy of wood and the non-uniformity of OSB structure make it difficult to measure the relevant mechanical property parameters, such as in-plane Poisson's ratio. Poisson's ratio is an elastic constant...

Wooden packaging boxes and pallets are used in a wide range of applications. In this work, LVL from the same source and batch were used as the base material. After dynamic detection and grading, they were divided into two grades (A and B), according to their differences in elastic modulus. The...

As a strategic new material with excellent performance, carbon fiber has attracted much attention in the wood structure industry. In this paper, the test modal and computational modal analysis methods are used to study the mode shape and modal parameters of carbon fiber board, calculate the elastic ...

Long-term sustainable biogas production requires different raw material alternatives, especially when reducing the most desirable organic substrate, food waste, which has been set as a goal in the 2030 Agenda. In Sweden, horse manure (HM) is generated in large quantities, and due to its physical...

Objective: When Timoshenko free beam iteration method is used to dynamically test the elastic modulus and shear modulus of wood, its test accuracy is greatly affected by the different length thickness ratios of the specimen. Therefore, this paper was implemented to explore the applicability of...

The microfibrillated cellulose (MFC) was prepared from cellulose hydrolyzed masson pine fibers by high-pressure homogenization. The properties of enzymatic hydrolyzed fibers were characterized by surface area and porosity analyzer, X-ray diffractometer and Fourier transform infrared spectrometer....

Demand has been growing for plywood utilizing novel formaldehyde-free wood adhesives which are more durable and require environmental protection and sustainable development during the service life. In this study, a series of HDPE film as novel adhesives in plywood due to many advantages are...
