This paper attempts to explore the influence to flexural performance of carbon fiber epoxy matrix composite circular tubes which were bonded in four different bonding Length with adhesive. Under the different bonding length, i.e. 20, 25, 35 and 40mm, the flexural performance of carbon fiber epoxy matrix composite circular tubes which were bonded were tested. It is shown that the bonding length affect the flexural properties of composite tubes. The flexural strength and elastic modulus of specimens CFRL50 increase about 18.11% and 36.95% respectively, compared to specimens CFRL20. The flexural properties of bonding composite tubes increased with the increasing length of reinforced pieces L2. Embedded bonding technology can provide a good bonding performance for composite circle tubes.

Transverse cracking induced acoustic emission in carbon fiber/epoxy matrix composite laminates is studied both experimentally and numerically. The influence of the type of sensor, specimen thickness and ply stacking sequence is investigated. The frequency content corresponding to the same damage mechanism differs significantly depending on the sensor and the stacking sequence. However, the frequency centroid does not wholly depend on the ply thickness except for the inner ply crack and a sensor located close enough to the crack. Outer ply cracking exhibits signals with a low-frequency content, not depending much on the ply thickness, contrary to inner ply cracking, for which the frequency content is higher and more dependent on the ply thickness. Frequency peaks and frequency centroids obtained experimentally are well captured by numerical simulations of the transverse cracking induced acoustic emission for different ply thicknesses.
