Solve surface defects of carbon fiber pipes for induction heating furnaces

Combined pre-compaction and temperature control

A key step in solving surface defects of carbon fiber pipes for induction heating furnaces is to combine pre-compaction with proper temperature control during the lay-up of carbon fiber prepregs. The exact operation method is in the process of laying materials. After laying several layers, it is convenient to carry out and pre-compact at a certain temperature, and apply a certain pressure to compress each layer of fibers. This immediate pre-compaction can To prevent the accumulation of fiber shrinkage layer by layer, under certain process conditions such as pressure and temperature, unnecessary resin, air bubbles and low-boiling substances in the prepreg blank are excluded, so that the blank is hard and actually reaches the predetermined thickness. The pre-compacted blank never needs to be sucked again during the curing process, and the resin content in the carbon fiber composite material and the thickness of the pipe can be precisely controlled.
