Introduction Wood plastic composites(abbreviation WPC), The definitions given in the American Society for Testing and Materials(ASTM) standards is "a composite material mainly in wood or cellulose-based materials and plastics(may also be a variety of plastic) ".
Compared to metal materials failure mechanism, woodworking tool failure mechanism is apparently different.
Otherwise, the installation mode can save experimental materials because of the interference problem.

It was shown that the mechanical performance of bamboo strip plywood was better than that of wood material such as Northeast larch, the compressive elastic modulus was lower than that of concrete, so that there existed a more great deformation when the bamboo beam structure was loaded, and the constitutive relations of bamboo materials showed that there was excellent ductility with an obvious characteristic of plastic deformation .
It also can be concluded that M1 can be seen as the anisotropic materials in the plane of the board because its compressive strength in direction of z axis is higher than in y axis.Instead,M2 can be seen as the isotropic materials for compressive strength is similar in z axis and in y axis.
Different size of the specimens caused different compressive strength.The size of the specimens can not be too small because bamboo plywood is combination materials,the effect of bamboo width should be considered.Based on the above consideration, 30 × 30 by 15 mm size can be adopted.

The study showed that the companies in the electrical and electronics industry that purchased material of a case study could not deliver materials on time from such purchase order.
Therefore, the frequency of transportation to deliver products shall be increase to minimize shortage of raw materials.
After returning material for packaging,the recycling materials are plastic bag and paper boxes.

However, these networks only solve the problem of interpersonal information exchange, but the material-material communication and material-human communication are still not well resolved.
In this context ubiquitous sensing technology emerges, which is to make our current information network an extensive, efficient, reliable system and to realize the large-scale implementation of material-material communication and materials-people communication[1-4].

Light intensity modulation is achieved by the change in refractive index of the modified cladding material when it is exposed to a chemical vapor.
This color change forms the basis for using PANi film as sensing material for detection of acid/base vapor.
