Authors: Chen Ling Fei , Chen Li , Zhang Guo Li
Published: September 2011

A 3D finite element model of three-point flexure test of carbon fiber/epoxy composite laminates is developed and analyzed with the finite element software ANSYS. Based on the Hashin criterion, a stiffness degradation method is adopted to predict the progressive failure properties of the carbon fiber/epoxy composite laminates. For carbon fiber/epoxy composite, five failure modes: fiber tensile failure, fiber compressive failure, matrix tensile cracking, matrix compressive cracking and fiber-matrix shear-out failure are included in the present model. The calculated load-displacement curve and the final flexural failure strength are compared with the experimental result, and the finite element results are in good agreement with the experimental values.

Published: September 2011

This research studied the preparation of the blended film from Bombyx mori silk fibroin with the regenerated cellulose obtained from rayon fiber residue, the industrial waste fiber. The β-sheet structure of silk fibroin was observed while the regenerated cellulose possessed cellulose II crystalline form. The infrared spectra of the blends showed changes in shape and intensity of IR absorption frequency characteristics in the region of 3500-3300 cm-1 as compared with those of the starting materials, pure silk fibroin and cellulose. This indicates the occurrence of the intermolecular interactions between the –OH groups of cellulose and silk fibroin by forming hydrogen bond. The tensile properties of the blends with cellulose content lower than 50 % could not be measured due to the weakness of the prepared film. The stronger and more flexible film was obtained with increasing the regenerated cellulose content. The study on the effect of NaCl and CaCl2 salt addition aiming to establish a porous structure to the blends was also investigated.

The experiment demonstrates that the cooling vest can alleviate the manikin’s skin temperature. When the constant energy input control mode is used, the manikin’s body parts covered by PCMs have lower skin temperature than other body parts; When the constant skin temperature mode is used, the manikin’s chest and back part, followed by the abdomen and buttocks part have the highest energy cost.

Authors: Zhang Xiang Hui , Li Jun
Published: September 2011

This paper reports on an experimental investigation of the effects of clothing ventilative designs on thermal comfort measured in terms of thermal insulation. Eight T-shirts with varying areas and locations of mesh fabric were designed and produced for testing on a dry thermal manikin. Clothing thermal insulation of T-shirts was measured under three wind velocities: 0.5, 1 and 2m/s. The results showed that, the areas and locations of ventilation panels affect the total thermal insulation. The T-shirts with larger area of mesh fabric are preferable in terms of releasing more body heat. Among various designs tested, mesh fabrics applied at two vertical side seams can most effectively release heat and moisture from the body. Clothing insulation is also greatly affected by wind.
