The present work aims to determine the impact performance of two bamboo-based laminated composites [bamboo/poplar laminated composite (BPLC) and bamboo/glass fiber laminated composite (BGFLC)] using low-velocity impact tests by a drop tower. In addition, fracture characteristics were evaluated using computed tomography (CT). Results showed that BPLC presented better impact properties in both directions than BGFLC. Three stages are noted in impact load–deflection curves. The load–deflection curve characteristics of two composites are different in different stages. Matrix cracking, fiber-matrix interface debonding and delamination, and fiber breakage are the three main fracture mechanisms of two composites. Structural characteristics of the components and bonding strength are the important factors for impact properties and fracture mechanism of both bamboo-based laminated composites. 相似文献

In a motive to develop a natural fiber-based dielectric material, bamboo fiber-reinforced epoxy composite is fabricated using hand layup technique and hybridized with Kevlar K29 fiber to enhance its properties. Dielectric and conductivity studies are performed using LCR meter on the composite samples as a function of frequency (100 Hz-1 MHz) and temperature (22–120°C). From the experiment, it is observed that the dielectric properties of bamboo-based natural composite are significantly enhanced by Kevlar hybridization. And also the influence of variation in frequency and temperature on the electrical properties i.e. dielectric and conductivity of the fabricated composite was studied. The morphological study is also carried out using scanning electron microscope (SEM). 相似文献
