Description
Technical Field
The invention relates to the field of composite materials, in particular to seamless composite fiber pipe manufacturing equipment and a seamless composite fiber pipe.
Background
The fiber reinforced composite material is prepared by mixing fiber materials (such as carbon fibers, glass fibers, aramid fibers and the like) with a high polymer resin matrix through processes of mould pressing, injection, resin transfer and the like, can achieve the purpose of improving the mechanical property of plastics, and is widely applied to various fields of aerospace, transportation, wind power generation, sports, industrial production and the like. Among them, carbon fiber reinforced composite materials and glass fiber reinforced materials are most widely used. However, the carbon fiber reinforced composite material and the glass fiber reinforced material have different advantages, and the carbon fiber reinforced material has higher mechanical property and structural stability but is more expensive; glass fiber reinforced composites are relatively inexpensive, but differ significantly in performance from carbon fiber reinforced composites.
Therefore, carbon fiber and glass fiber are sometimes used together to produce a hybrid fiber glass composite, which is expected to be superior to each other. For example, patent CN1915884A discloses a hybrid carbon fiber-glass fiber reinforced resin rib, which is composed of carbon fibers, glass fibers, vinyl resin, curing agent and accelerator, has good ductility and yield property, and is lower in price than carbon fiber reinforced resin. Patent CN103061565A discloses a tapered tube made of a glass fiber and carbon fiber hybrid composite material, which is formed by winding an inner carbon fiber reinforced resin layer and an outer glass fiber reinforced resin layer, and has a tensile modulus higher than that of glass fiber, and the forming process is simple. The above patents all use the carbon fiber and the glass fiber to mix to prepare the fiber reinforced material, but the difference of the mechanical properties of the carbon fiber and the glass fiber causes that the mixed fiber reinforced material can not reach the due mechanical properties, which limits the application range. Therefore, a seamless composite fiber pipe manufacturing device and a seamless composite fiber pipe are provided to solve the problems.
