Abstract

PURPOSE:To laminate the above material without disorder of fiber and to mold and assemble economically a structural material with a complex shape by a method wherein after a molding raw material is set between bag materials, spaces between them are evacuated and it is melted by heating and vacuum-molded under atmospheric pressure and after the vacuum- molded molding raw material is joined with a split tool, it is molded by means of a hot press and the obtd. beam structural body and an outer sheet obtd. separately by means of hot press molding are connected by heating. CONSTITUTION:A molding raw material 11 is enveloped with vacuum bag materials 12 and vacuum-backing of the ends thereof are performed. Then, the vacuum-bagged body of the molding raw material 11 is brought into a condition wherein vacuum-bagging can be done on a mold 14. Successively, a heater mat 16 is set on a vacuum bag material 12 and after it is heated up to a temp. wherein a resin of the molding raw material 11 is melted, vacuum evacuation is performed and the lamination is pushed on the mold 14 and molded under atmospheric pressure. A J-shaped beam is vacuum-molded by using split molds 17 and 18 and beam elements 20 and 21 are assembled in molds 17, 18 and 19 and heat press molding is performed by means of a hot press 22 to mold the J-shaped beam 23. The beam 23 and an outer plate 25 are melted and joined by using a fusion rod 26 and by means of laser heating 27.

ある。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for molding a thermoplastic resin composite material, and is particularly applicable to panel structural parts of aerospace equipment.

）。An example of conventional molding is as shown in Fig. 8 (4) to (I).
The molding material 1 is laminated using an electric iron (or an ultrasonic welding machine), and then the girder 2 is formed by gas pressure molding in a hot press molding using a hydraulic press device (or an autoclave device). The outer panels 3 are each shaped, and then adhesively assembled by curing in an autoclave using a niboxy resin adhesive 4 (or the girders and outer panels are mechanically assembled using fasteners).

〔発明が解決しようとする課題〕[Problem to be solved by the invention]

従来技術による熱可塑性樹脂系複合材料の成形では、以
下の問題点を有する。Molding of thermoplastic resin composite materials by conventional techniques has the following problems.

（１）室温では硬くて粘着性のない成形素材を１枚１枚

繊維の乱れが発生しやすく、積層形状が単純なものに制
限され、また積層に時間がかかる。(1) When molding materials that are hard and non-tacky at room temperature are laminated one by one, they are partially joined using an electric iron or an ultrasonic welding machine, so the laminate is dense and heavy. Fibers tend to be disordered due to misalignment, the laminated shape is limited to simple ones, and lamination takes time.

More vacuum A? The resin is heated and softened by heating only the molding material part from the rack with a heater mat, and vacuum bagging is carried out onto the molding mold to easily vacuum form it into the molding mold at a low temperature using atmospheric pressure.

具で合体することで、ホットプレス成形が可能となる。Next, a complex shape such as a J-shape can be easily hot press molded by using a one-piece jig without using an expensive autoclave device. Hot press molding becomes possible by combining the constituent elements of the J-shaped girder with a jig whose mating surfaces of the molds are inclined at, for example, 45° and which can apply pressure to the entire surface.
