The tension–tension fatigue behavior of (the layer-to-layer) three-dimensional angle-interlock woven composite (3DAWC) was investigated using the acoustic emission (AE) technique, examination of damaged regions via light microscopy and micro-CT, and finite element analysis (FEA). AE events occurred during the entire fatigue process, and damage modes were determined based on cumulative fatigue d...

Carbon fiber reinforced polymer (CFRP) sheets can be externally bonded for retrofit of concrete structures, improving flexure and sheer strength in the concrete. The key to CFRP sheets is the bond to the concrete, as bond is the means to transfer stress between the tow sheet and the concrete. Experimentation has been conducted to test a current market fiber-resin system, and to develop a resin ...

Humid tropical climate favours the existence of a corrosive atmosphere that causes deterioration of metals. This article describes an automated system for monitoring environmental values (temperature and relative humidity) in order to know the time of wetness (TOW), which is key factor in determining the atmospheric aggressiveness which are exposed the metals used, for example, in industrial fa...

Three fractures at the base of the terminal phalanx of the finger and one at the base of the terminal phalanx of the tow were initially misdiagnosed as paronychias. If a 'paronychia' follows trauma, the possibility of a fracture should be considered and radiographs taken of the digit.
