The present invention discloses a melt impregnation device and a melt impregnation method. Through an impregnation chamber with a corrugated shape, when a resin melt-distributing runner is connected with a peak position of the impregnation chamber, a chamber vertical height of the peak position of the impregnation chamber is larger than a chamber vertical height of a trough position of the impregnation chamber, and when the resin melt-distributing runner is connected with the trough position of the impregnation chamber, the chamber vertical height of the trough position of the impregnation chamber is larger than the chamber vertical height of the peak position of the impregnation chamber. The present invention can balance an impregnating effect of a continuous fiber band, can carry a broken fiber hairiness which is generated during the impregnation out of an impregnation area, avoids a broken yarn, and enhances a production stability and a production efficiency.

Melt impregnation device and melt impregnation method

An alternating pressure melt impregnation device and a melt impregnation method, including having a resin melt squirted from each resin melt runner on an upper die and a lower die of a melt injection area, and thus the squirted resin melt is enable to be squirted directly on an upper surface and a lower surface of a continuous fiber bundle which is entering into an impregnation chamber. Impregnation and infiltration for both surfaces of the continuous fiber bundle are primarily completed by a squirted pressure. The resin melt inside the impregnation chamber flows to a decompression chambers at both sides of the impregnation chamber. When the resin melt flows to a throttle plate, a re-impregnation for the continuous fiber bundle is realized. Then the pressure is decreased and a section of the resin melt is enlarged and a radial flow is generated due to the Barus effect.
