Manufacturing system for epoxy FRP pipes using internal heating curing process

In order to improve production efficiency and product quality of epoxy FRP pipes,the integrated manufacturing system for FRP pipes was developed,which can perform three manufacturing processes of winding,curing and extraction by only one machine tool.This paper introduces the mechanical structure and operating principle of the machine tool,establishes the winding motion control model and the curing process model.The winding control system adopts embedded multi-task motion controller to undertake synchronous motion control of the spindle and the carriage and logical control of the winding operations.The internal heating curing process is used to cure the pipes,and the curing control is fulfilled by an embedded industry computer and a PLC.The numerical simulation of temperature and degree of cure distribution during curing process was conducted by finite element software to optimize the curing process parameters.The performance of the FRP pipes manufactured by this system was tested.It is proved that applying internal heating curing process can realize industrialized manufacturing of epoxy FRP pipes with high efficiency.
