| Abstract: | The micro-failure process of three-point bending and shearing strength on Moso bamboo-Chinese fir laminated composites under loading was investigated by the in-situ linear-scan electron microscope method (ISL-SEM). The typical failure regularities were analyzed in accordance with the images observed by scanning electron microscope. The breakage patterns of Moso bamboo-Chinese fir laminated composites, including shearing failure after air-dry and water soaking and bending failure under air-dry condition, were also summarized. |
