“…In another work by Shah et al (2013) the S-N curves of different plant fiber/yarn polyester composites showed similar trends. However, a high-tech bamboo/epoxy composite made from Chinese Moso bamboo is reported to reach a 80 MPa fatigue limit (Platts 2014). In the composite, the transition region could have a slight influence on the fatigue data. The transition region is normally can be related to the types of damage that the composite experiences.…”

The fatigue and fracture properties of bamboo fiber composites made of woven layers were investigated. This study utilized a specific type of bamboo species named Gigantochloa scortechinii (Buluh Semantan). In these experiments, unsaturated polyester (UP) and bamboo fiber (BF) strips were prepared through a hand lay-up technique using 3-mm thick aluminum mould. The composite bamboo strips had a thickness of 1.5 mm. The strips were woven together to make a single layer. The layer was then laminated into several thicknesses. The specimens were then characterized using fatigue and fracture tests. A fatigue limit of 30 MPa and fracture toughness of 5 to 8 MPa √ were obtained. These findings suggest that the bamboo strips, based on unsaturated polyester, provided relatively good fatigue and fracture properties and a good method of reinforcing fibers to combat fatigue and fracture failures.

“…Holmes et al [ 161 ] produced a novel bamboo-poplar epoxy laminate for blades formed by hot-pressing and carried out mechanical testing of the laminates (monotonic tensile and compressive stress-strain behavior and tension-tension fatigue life). Platts [ 162 ] presented strength test results for Brazilian Dendrocalamus Giganteus bamboo. He demonstrated the important effect of the moisture content on strength and stiffness and proposed to coat the bamboo with epoxy resin, to create a vapor barrier and preserve the dryness.…”

Various scenarios of end-of-life management of wind turbine blades are reviewed. “Reactive” strategies, designed to deal with already available, ageing turbines, installed in the 2000s, are discussed, among them, maintenance and repair, reuse, refurbishment and recycling. The main results and challenges of “pro-active strategies”, designed to ensure recyclability of new generations of wind turbines, are discussed. Among the main directions, the wind turbine blades with thermoplastic and recyclable thermoset composite matrices, as well as wood, bamboo and natural fiber-based composites were reviewed. It is argued that repair and reuse of wind turbine blades, and extension of the blade life has currently a number of advantages over other approaches. While new recyclable materials have been tested in laboratories, or in some cases on small or medium blades, there are remaining technological challenges for their utilization in large wind turbine blades.

“…Therefore, a combination of two materials with natural fibers produces a stronger and more corrosion-resistant material. It also improves the stiffness, strength and moisture-resistant behavior of the composites (Aidy et al, 2016;Verma and Chariar, 2012;Porras and Maranon, 2012;Yeh and Lin, 2012;Yao and Li, 2003;Li et al, 2002;Van der Lugt et al, 2006;Obataya et al, 2007;Shao et al, 2010;Biswas and Satapathy, 2010;Liu et al, 2012;Anwar et al, 2009;Darshil et al, 2013;Harris, 2003;Toshihiko et al, 2014;Amada and Untao, 2001;Platts, 2014).

Purpose The purpose of this paper is to investigate the fracture properties of hybrid woven bamboo (WB)/woven e-glass (EG) fiber composites with various layer arrangements. This paper utilized a specific type of bamboo species named Gigantochloa Scortechinii (Buluh Semantan). Design/methodology/approach In these experiments, unsaturated polyester, woven EG and WB fibers were prepared through the hand lay-up technique. The composite bamboo strips were prepared in 1.5 mm thickness. The strips are woven to make a single layer. The layer was then laminated into several thicknesses. The specimens were then characterized using compact tension fracture tests. Findings The fracture toughness of 12–14 MPa was obtained. These findings suggest that this hybrid bamboo composite provides superior fracture strength that is equivalent with steel alloy and is extremely a good alternative for reinforcing fibers to combat fracture failures of materials and structures. Originality/value In this paper, experimental determination of newly developed composite made of WB and woven EG is presented.
