“…A lignina, individualmente, entretanto, apresentou valores semelhantes, antes e depois do tratamento em água, em todos os materiais estudados. O valor de lignina obtido por SANCHEZ-ECHEVERRI et al [42] para o bambu de 15,50%, porém, obteve uma grande redução após o pré-tratamento, chegando a 9,70%. De acordo HUANG et al [43], as partes mais grossas das fibras de bambu e pinus apresentam uma maior lignificação (valores acima de 20,00%) e o tratamento com água quente não apresentou grande influência na variação deste componente.…”

“…Já para a holocelulose (celulose e hemicelulose), observa-se que não houve redução ou aumento geral destes componentes químicos, diferentemente do encontrado no trabalho de SANCHEZ-ECHEVERRI et al [42], no qual as partículas de bambu apresentaram, após tratamento, redução de 34% da holocelulose. Todos os dados de apresentados, por outro lado, foram superiores a 12%, após os tratamentos com água quente; isso está relacionado com às regiões amorfas e a alta capacidade de absorção de água [3].…”

RESUMO O presente trabalho tem como objetivo analisar o efeito de diferentes espécies de madeiras e de bambu (Pinus taeda, Cereus jamacaru e Bambusa vulgaris) na hidratação de matrizes cimentícias. Para tanto, os materiais lignocelulósicos foram moídos e caracterizados antes e depois de tratamento em água quente. Posteriormente, o efeito da adição de diferentes níveis (5, 10 e 33,3%) de madeiras, pré-tratadas ou não, em pastas de cimento foram analisados a partir dos ensaios de calorimetria isotérmica e termogravimetria. Os resultados demonstraram que as partículas de cada espécie lignocelulósica apresentaram um aumento das propriedades de umidade e absorção concomitante a diminuição de suas densidades e níveis de extrativos a partir do pré-tratamento aplicado. Os outros componentes químicos destes elementos, majoritariamente, todavia, não foram afetados. Por outro lado, foi observado que quanto maior o teor de tais materiais lignocelulósicos, pré-tratados ou não, nas matrizes de cimento, maior o impacto na hidratação do cimento, segundo o ensaio de calorimetria. Já com relação ao resultado do ensaio de termogravimetria observou-se uma tendência geral, com ou sem pré-tratamento de partículas ou adição de água de compensação, de aumento dos produtos hidratados, fato atribuído, principalmente, a presença de água livre e gases nos materiais lignocelulósicos.

“…Akinyemi et al [78] studied the effects of different pre-treatment methods on bamboo fiber cement composite materials and observed that microwave-assisted alkali treatment enhanced mechanical properties. Sanchez-Echeverri et al [79] compared the performance of bamboo fiber reinforced cement made from treated and untreated bamboo fibers and reported that the applied alkali treatment produced enhanced flexural strength. They also observed that after alkali treatment, the impurities on the surface of the bamboo fiber were significantly reduced giving a cleaner surface (Fig.…”

“…They also observed that after alkali treatment, the impurities on the surface of the bamboo fiber were significantly reduced giving a cleaner surface (Fig. 9) [79]. Huang et al [80] analyzed the applicability of bamboo fiber and bamboo charcoal resources as building fillers in tropical and subtropical regions through the hygrothermal properties test as well as through simulation of the building component and the enclosed space.…”

Fibers are used in many forms in engineering applications-one of the most common being used as reinforcement. Due to its renewable short natural growth cycle and abundance of bamboo resources, bamboo fiber has attracted attention over other natural fibers. Bamboo fiber has a complex natural structure but offers excellent mechanical properties, which are utilized in the textile, papermaking, construction, and composites industry. However, bamboo fibers can easily absorb moisture and are prone to corrosion limiting their use in engineering applications. Therefore, a better understanding of bamboo fiber is particularly important. This paper reviews all existing research on the mechanical characterization of bamboo fiber with an emphasis on the extraction and treatment techniques, and their effect on relevant properties. The chemical composition of bamboo fibers has also been thoroughly investigated and presented herein. Current applications and future opportunities for bamboo fibers in various fields have been presented with a focus on research needs. This work can serve as a reference for future research on bamboo fiber.

Characterized by rapid maturation, short growth cycles, and high strength and toughness, bamboo can be compounded with polymers to produce bamboofiber reinforced polymeric composites (BFRPCs). These composites exhibit corrosion resistance comparable to traditional materials such as glass fiber and carbon fiber composites. Additionally, they possess features like low density, high strength, degradability, and environmental friendliness, with low production costs and strong industrial applicability. This paper reviews the accomplishments in BFRPCs and provides an overview of the production processes for BFRPCs. Furthermore, it summarizes the research status of mechanical properties, moisture absorption characteristics, interface performance, and flame retardancy of these composites. The current issues with BFRPCs were analyzed. Finally, the paper explores future research directions and potential applications of BFRPCs.Highlights The performance studies on BFRPCs are comprehensively presented. Composite processing of BFPRCs is reviewed. Pros and cons of various types of BFRPCs are analyzed. Overview of the applications of BFRPCs in various domains is presented. Future trends and challenges of BFRPCs are introduced.
