この発明は繊維マットへの樹脂含浸方法に関し、詳しく
は粘稠性を存した未硬化樹脂を連続的に繊維マノ１〜へ
含浸させていく方法に関する。[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to a method of impregnating a fiber mat with resin, and more specifically, a method of impregnating a viscous uncured resin into a fiber mat continuously. Regarding the method.

かの加圧手段を必要とする。Traditionally, to reinforce synthetic resin products, it has been widely used to impregnate fiber mats such as glass fiber non-woven fabric with resin and harden them. However, in the case of highly viscous resins, almost uniform impregnation is not possible without pressure, and some kind of pressure means is required.

is dammed up with a doctor knife D, etc., and a pressure roller E is placed in the resin stagnation C', and this roller E is reciprocated in a direction perpendicular to the conveying direction (arrow X) of the conveyor A, thereby increasing the viscosity. It was previously proposed to impregnate resin C with a high content.

成出来ないことが有る欠点が有った。However, when using the above method, the air bubbles contained in the fiber mat sheet B may not be degassed properly, and resin impregnation may be performed with the air bubbles still contained, resulting in a disadvantage that uniform impregnation may not be achieved. It was.

法を得ることを目的としてなされたものである。In view of the above-mentioned drawbacks, this invention aims to provide a method for impregnating a fiber mat with a resin that can continuously impregnate a fiber mat-like sheet with a highly viscous resin without entrapping air bubbles. It was done for a purpose.

Pressure is applied from above the fiber mat by reciprocating the fiber mat sheet over its entire width in a direction substantially perpendicular to the traveling direction of the fiber mat sheet using a roll having a large number of circumferential grooves arranged in parallel on its surface. .
次にこの発明の方法を実施装置により説明する。 Next, the method of the present invention will be explained using an implementation device.

させつつ加圧する構成とされている。The method of impregnating a fiber mat with resin according to the present invention involves supplying a viscous resin 2 onto a heald conveyor l, smoothing it into a layer of a constant thickness using a doctor knife, etc. A roll 4 is used to supply a fiber mat 3 consisting of layers in a layered manner, and a roll 4 has a large number of degassing circumferentially spaced li&4B...4B arranged side by side on the surface 4A from above the fiber mano 1-3.
The structure is such that pressure is applied while reciprocating the fiber mats 1 to 3 over the entire width thereof in a direction perpendicular to the transport direction (arrow X) of the fiber mat 3 (direction of the back of the paper in the figure).
上記において帖調性を有する樹脂としては、レゾール系

出される。In this invention, since the pressing force by the roll 4 is applied from above the fiber mats 1 to 3, the resin 2° is
It permeates from the lower surface to the -L surface, and the air contained inside escapes through the gaps between the fibers to the -L surface and is released into the atmosphere.
なお、ロール４には周方向溝４Ｂ・・・４Ｂが有るので
、脱気もスムーズに行なえる。In addition, since the roll 4 has the circumferential grooves 4B...4B, degassing can be performed smoothly.

ある。As explained above, this invention takes advantage of the viscosity of the viscous resin and presses the fiber mat onto the resin layer, allowing for very smooth degassing and trapping of air bubbles. A uniform, resin-impregnated mat without any lumps can be obtained.
