The research objective is to determine the maximum bending strength of woven bamboo composite materials.
The use of several materials is one of the efforts to increase the mechanical and physical strength.
The composite specimen was made in the materials laboratory at STT Warga Surakarta.
Flexure testing is carried out in the materials laboratory at Mechanical Engineering UNS Surakarta.
The materials and equipment used in this study were 108 polyester series resin, molds and lids made of 10 mm thick plywood.

Serpentine jade is one of the most important materials for producing jade artifacts, and there are numerous serpentine deposits in China [3].
Furthermore, trace element concentrations can also be used to infer the original source of the raw materials of the jade artifacts, providing important insights into the archaeological study of archaic jade artifacts.

Yap and Skitmore [11] and Bassa et al. [29] noted that DCs play a major role in increasing the wastage of materials, resources and rework, while Dosumu and Aigbavboa [30], Zaneldin [31] and Howick [32] highlighted the impact of DCs on increasing project variations, claims and disputes between project parties.
By involving more people in the design phase, leveraging new technology and materials, maintaining quality consistency, and delivering projects faster and with higher quality, CE boosts productivity and prevents errors [52].
ADFs are responsible for producing uncoordinated and incorrect construction documents, specifying outdated building materials or technologies, ignoring the role of the client and behaving unilaterally [64].

Control alloy corrosion can follow these ways: (1) correctly choose metal or non-metallic materials according the using environment; (2) Reasonable design of configuration and technology of material. (3) To improve environment of application; (4) Adopting electrochemical protection for products. (5) Passivating on the surface of products.
The erosion rate of sample annealed at 680℃ is lowest, and the brass has better erosion resistance in artificial perspiration solution than in artificial acid rain or 3.5%NaCl solution Foundation item: This research is supported by Natural Science Foundation of Jiangxi (No.2009GZC0048), by Open Foundation of Jiangxi Key Laboratory for Advanced Copper and Tungsten Materials (No.2010-WT-03) References [1] Qiuxia SUN.

Introduction With the progress of science and technology, new fibers emerge in endlessly.
Same raw materials of 12 fabrics are in same yarn fineness, the specifications as shown in table 1.
Fabric raw materials have great influences on fabric strength, the burst resistance of PA/ S/ PU is better than PA/ PU because of the addition of sorona fiber, which proves that sorona fiber strength is excellent.
The hygroscopicity and air permeability Conclusions earned from experimental data: 1, fabric hygroscopicity is related to raw materials, and from large to small as: PA/ PU > PA/ S/ PU > PL/ PU. 2, Fabric air permeability rate is between 70 mm/s to 150 mm/s.

Human needs is three-dimensional, it includes multiple levels of material needs, spiritual needs and ecological needs.
Usually the basic material needs have been met, the spiritual consumption determines the quality of human life.
Fifthly, Principle of Scientific Consumption Environment-friendly consumption is a scientific and civilized consumption, is a healthy consumption guided and formed by scientific knowledge, make people's consumption both meet the requirements of science, health, happiness, and satisfy the need of energy saving, environmental protection, at least not cause damage to the ecological environment, not waste of natural resources, realize the material reproduction and labor reproduction in harmony with the natural resources and ecological environment and sustainable development.
Such as: on food, translate from pursuing the fine, the high-grade food to pursuing the nutrient balance and preventing pollutants from entering the human body; On the housing, translate from pursuing luxury interior decoration to paying more attention to the house ventilation and daylighting, reducing the pollution of the building materials radiation effect; On clothing consumption, translate from pursuing high-grade, luxury, fashion to paying more attention to practicality and nature, choosing ecological clothing; In terms of "line", choose more energy-saving and pollution-free green transportation, etc.
