Abstract

The invention discloses a basalt type continuous fiber coiled and reinforced bamboo-wood combined pipe. The pipe comprises inner fiber reinforced resin, single-board laminated timber and/ or bamboo, medium fiber reinforced resin, another single-board laminated timber and/ or bamboo, and a surface fiber reinforced resin which are sequentially coiled from inside to outside; the fiber reinforced resin is resin soaked basalt fiber, glass fiber, aramid fiber and carbon fiber; the bamboo is one or a plurality of bamboo strips, bamboo plates, spliced plates, bamboo splits and expanded bamboo; the single-board laminated timber is one or a plurality of poplar, eucalyptus, birch, cedarwood, masson pine and pinus sylvestris. With the adoption of the pipe, the cost is greatly reduced, the density is reduced, and the ratio of strength to weight is obviously increased.

Description

technical field [0001] The invention relates to a composite pipe, in particular to a basalt continuous fiber winding reinforced bamboo-wood composite pipe. Background technique [0002] At present, the structural forms of fiber-wound reinforced resin pipes mainly include the following types: pure fiber resin pipes without sandwich materials, and steel, concrete, quartz sand and other sandwich materials. [0003] The disadvantages are: high density, high cost, and low strength-to-weight ratio. Contents of the invention [0004] The object of the present invention is to provide a basalt continuous fiber winding reinforced bamboo-wood composite pipe with low density, low cost and high strength-to-weight ratio. [0005] The purpose of the present invention is achieved through the following technical solutions: [0006] The basalt continuous fiber winding reinforced bamboo-wood composite pipe of the present invention is characterized in that it comprises inner layer fiber rei...
