In this paper the principle and experimental process of the infrared thermal wave nondestructive testing (NDT) on carbon fiber reinforced silicon carbide (Cf /SiC) ceramic matrix composite sample are demonstrated. The experiment results compared with X-ray testing results show that the infrared thermal wave NDT is an effective method for the Cf /SiC ceramic matrix composite, and it can be used ...
Six ruminally fistulated Hereford steers (body weight=414±13 kg) were used in a switch back design to determine whether two particle sizes of alfalfa hay (18.75 and 4.65 mm theoretical cut length) influenced salivary secretion during eating. The experiment carried out in two 26-d periods, with 11-d of adaptation to ration, followed by 5 d for determining the level of voluntary feed intake, 7-d ...
effective elastic properties for carbon nanotube reinforced composites are obtained through a variety of micromechanics techniques. an embedded carbon nanotube in a polymer matrix and its surrounding interphase is replaced with an equivalent fiber for predicting the mechanical properties of the carbon nanotube/polymer composite. the effects of an interphase layer between the nan...
An experiment was carried out to determine the effect of corn silage particle size and fat supplements on performance, solid passage rate through the digestive tract, and chewing behavior in dairy cows. The forages were coarse or fine corn silage with geometric means of 8.8±2.7 and 5.6±2.8 mm, and alfalfa with geometrics means of 7.0±3.3 mm, and fat supplements were neutral fat (palm) and soy-o...
