There is a pressing need to develop engineering standards for timber- and other wood-based mats suitable for supporting construction vehicles, etc. In 2018, a group of mat producers and users began discussing a potential grading standard specific to mats. There are large gaps in the literature regarding the performance of the available raw materials as well as bolt-laminated mat systems. This study addresses the issue of determining the strength and stiffness values of a commercially sourced industrial bamboo mat. A total of seven 8 ft × 14 ft (2.44 m × 4.27 m) commercial bamboo mats were cut into 28 billets that were 21.5 in (54.6 cm) in width. The bamboo mat billets were evaluated for bending stiffness (modulus of elasticity [MOE]) and strength (modulus of rupture [MOR]) using a three-point static bending test. The 5th percentile non-parametric tolerance limit (5% NTL) and design value for fiber stress in bending (Fb) were calculated. The mechanical property values measured for the 3-ply bamboo mat were at least 25% less than values reported for mixed hardwood timber mats. This type of structural performance information is helpful and useful in the development of matting standards, as it describes the minimum performance characteristics for this type of composite matting.

Mercury intrusion porosimetry (MIP) is a technique used to characterize the pore size distribution and resin penetration in lignocellulosic materials, such as oriented strand board specimens (OSB), a multilayer panel utilized in structural applications. The method is based on the isostatic injection, under very high pressure, of a non-wetting fluid (mercury) into the porous material to determine parameters such as pore size distribution and percentage of porosity of the specimens. In this study, five different OSB were analyzed; they contained different wood species, resin type, and resin content. The panels manufactured with castor oil polyurethane resin showed porosity values in the range of 54.7 and 27.8%. This was a promising result compared with those obtained for panels made with phenolic resins, which are currently commercialized in Brazil.

Furniture design has undergone a significant transformation over the centuries, evolving from purely functional objects to artistic expressions that reflect societal values, technological advancements, and environmental concerns. In contemporary society, furniture design plays a critical role not only in shaping interior spaces but also in influencing lifestyle, culture, and sustainability. The modern emphasis on minimalism, ergonomics, and multifunctionality reflects changing living patterns, urbanization, and an increased focus on well-being. Technological innovations, such as digital fabrication and smart materials, have further expanded the possibilities of design, enabling more personalized and efficient solutions. Additionally, there is a growing consciousness around sustainable practices, leading to the use of eco-friendly materials and circular design principles. This evolution highlights the intersection of aesthetics, utility, and ethics in modern design. By examining key trends and innovations, this study explores how contemporary furniture design responds to the needs of a dynamic society and contributes to shaping the future of living environments.

This study explores Cyprus’s long-standing and rich heritage of carving wooden furniture, a craft that plays a significant role in the island’s artistic, cultural, and historical narrative. The Cypriot woodcarving heritage is a singular fusion of artistic, religious, and practical craftsmanship. It has roots in centuries-old techniques and influences from succeeding civilizations such as Byzantine, Venetian, and Ottoman. This study investigates the dissemination of carving methods, the development of artistic motifs, and the socio-cultural meanings ingrained in the carved items using an interdisciplinary approach that combines historical research, fieldwork, and interviews with modern artists. Religious iconography, the vine, and the rosette are examples of traditional motifs that are examined as both decorative accents and symbols of shared memory and identity. The research also analyses regional variances across the island, from the intricate furniture of the Troodos region to the simpler, yet symbolically rich, home objects found in rural towns. The materials utilized—especially local hardwoods like walnut and olive—as well as the specialized hand tools and techniques used by expert carvers are all carefully considered. The study shows how, despite the demands of mass production and modernization, these artisans have preserved a high level of technical and symbolic continuity.

The study explores the significance of wood as a surrogate of nature in Chinese traditional dance, emphasizing its dual role as both a medium for cultural transmission and an element of artistic expression. Through the analysis of wooden props such as fans and drums, the study reveals the symbolic meanings conveyed by wood in dance and its deep connection to nature and life. Through their biophilic interaction with wood, dancers articulate a reverence for nature and reflections on life, creating a unique cultural resonance with the audience. Case studies of the Han ethnic group’s Jiaozhou Yangge Fan Dance and the Tibetan Reba Dance illustrate the important role of wood in emotional expression and cultural identity. Future research can focus on the innovative incorporation of wood in contemporary dance to promote the integration of traditional and modern dance arts.

As the cradle of civilization, Egypt has historically been at the center of the development of writing supports, which were first developed from the local papyrus, but later gradually replaced by true paper. This paper delves into Egypt’s historic change in writing materials. Used for over 4,000 years since around 3000 BCE, papyrus was a central element in the administrative and religious activities of the ancient Egyptian civilization, and the method of its production was an industry secret. The advent of true paper in the 8^th century CE, which involved breaking down plant tissue to release fibers, marked the beginning of a cultural change that led to the phasing out of papyrus under Islamic rule. By the time the 12^th century CE came around, the making of papyrus had essentially stopped, as paper had taken over, being both more durable and versatile. This study investigates the following: the reign of papyrus; the history and material science of papyrus; the technological shift from lamination to maceration, and comparative analysis of writing supports.
