Abstract

Official abstract text for this publication.

The present disclosure provides an impregnation device for a fiber prepreg, which includes a film layer separation assembly, a hot pressing element, and a thermal barrier element. The hot pressing element is disposed beneath the film layer separation assembly. The thermal barrier element is disposed between the film layer separation assembly and the hot pressing element. The present disclosure also provides an impregnation method for a fiber prepreg.

First claim

Opening claim text (preview).

What is claimed is: 1. An impregnation device for a fiber prepreg, comprising: a film layer separator, comprising: a first roller; a film layer receiver disposed over the first roller; and a second roller disposed between the film layer receiver and the first roller in a vertical direction, and a separation angle between a direction of the first roller facing the film layer receiver and a direction of the first roller facing the second roller being greater than 0°; a resin film provider disposed over the first roller, and when projected vertically on a horizontal plane where the first roller is located, the resin film provider and the film layer receiver being respectively located at opposite sides of the first roller, wherein the horizontal plane where the first roller is located is perpendicular to the vertical direction; a fiber provider disposed beneath the film layer separator; a hot pressing processor disposed beneath the film layer separator in the vertical direction; and a thermal barrier disposed between the film layer separator and the hot pressing processor in the vertical direction, wherein the thermal barrier comprises an insulating material and is arc-shaped, and a concave shape of the thermal barrier only faces the hot pressing processor to converge heat at a side of the hot pressing processor. 2. The impregnation device of claim 1 , wherein a position of the second roller is adjustable, and a separation angle is able to be changed by changing the position of the second roller. 3. The impregnation device of claim 1 , wherein the insulating material comprises a porous material, a heat reflective material, or a combination thereof. 4. The impregnation device of claim 1 , wherein a surface of the thermal barrier close to the hot pressing processor is made of a heat reflective material. 5. The impregnation device of claim 1 , wherein when projected vertically on a horizontal plane where the hot pressing processor is located, a projection of the thermal barrier is coincident and larger than a projection of the hot pressing processor, wherein the horizontal plane where the hot pressing processor is located is perpendicular to the vertical direction.
