JPS60102261A - Quality inspection of fiber reinforced composite member - Google Patents

Abstract

PURPOSE:To judge whether the quality of a product is defective or non-defective in the stage of producing a fiber reinforced composite member by application of a high pressure solidifying and casting method by measuring the overall advancing speed of plural locally pressurizing punches and the entire stroke volume thereof with respect to the entire product part. CONSTITUTION:A sprue 3, a cavity 4 and a well 5 are communicated with the mating faces of a casting mold M. One end of a fiber molding F is held in the groove 8 at the tip of a core 7 and after the molten metal supplied from a hopper 11 to the sprue 3 is sealed by a plunger 10, the molten metal in the mold M is primarily pressurized to a half molten state by a plunger 12 and is secondarily pressurized by local pressurizing punches 131-133 to pack and combine the molten metal into and with the molding F. The fiber reinforced composite member is decided to be non-defective when the overall advancing speed of the punches 131-133 is in the range of 2.4-7.2cm<2> per second and the stroke volume of all the punches 131-133, i.e., the sum of the volume of recesses 151-153 is in the range of 5-15% of the entire volume of a product 4. Whether the product is defective or non-defective is thus decided.

Description

[Detailed description of the invention] The present invention relates to a quality inspection method for fiber-reinforced composite members.

The present applicant has previously described a method for manufacturing a horizontal line-reinforced composite structure.
A method of shaping the composition of a rod installed in the cavity of a mold (Special Issue), Vol. 1987-17: Hi No. 87) is proposed. If this method causes unfilled areas to occur in the composite part of the above-mentioned parts, it will not be possible to exhibit sufficient fiber reinforcing ability, so a quality inspection is conducted.
Conventionally, X-ray or ultrasonic inspection equipment has been used, which is uneconomical as it requires a lot of equipment costs and labor.

In view of L, the present invention uses a simple method to inspect the quality of IN 141 Reinforcement Department. - The purpose of this method is to provide a method in which the overall approach speed of a small number of local υ11 pressure corbels is 24 to 7.2 cra/s e
It is characterized in that it is considered to be a good product if it is within the range of c and the stroke volume of all 11 local pressure punches is within the range of 5 to 15% of the entire product part IIi.

Hereinafter, one embodiment of the present invention will be explained with reference to the drawings. Figure 2 shows the scale part, which has been strengthened by 1 precept 8.11 (ζsu, 1, which can be raised and lowered for 1, and 2, and both!! I:) 1 and 2 combined. As a result, the sprue 3, the conorod molding key/bidet 4, and the sprue portion 5 are formed in sequence as shown in FIG. The cavity 4t11 communicates with the large end molded part 40 through the gate 6, and the large end molded part 40 communicates with the water reservoir part 5 through the gate 62. , and the two parts 4a, , 4A are connected to each other (S molding part 4 (), and the water reservoir part 5 has a small volume!
