The document summarizes the research and development of bamboo composite pressure pipes by a company in Zhejiang province, China. It describes the 8-year R&D process including early experiments in 2007 that validated the concept. It also outlines the company's plans to promote the pipes which include establishing a production alliance and investment fund with the goal of producing 10 million tons annually by 2020 to generate 200 billion yuan in output value. This would create social benefits such as increasing farmers' incomes and providing urban jobs.

2、竹复合压力管的定义
Definition of Bamboo composite pressure pipes
以竹子为基材,以树脂为胶黏剂,采用机械
缠绕方式加工成型的生物基压力管道。
They are kinds of biological base pressure pipes which
manufactured from using bamboo as basic material and
resins as adhesives, by mechanical winding way.

充分利用竹纤维的轴向拉伸强度高的特点,并在管
材结构中形成无应力缺陷分布,将竹纤维的轴向拉
伸强度发挥至最大化,从而使管材达到更好的承压
效果。
Making the most of bamboo fiber’s property of high axial tensile
strength, and also forming non-stress defect distribution in pipes
structure, to maximize the axial tensile strength of bamboo fiber,
thus to make pipes reach better bearing pressure result .
