Methods of RTM molding |
摘要 |
A method of RTM molding including laminating a plurality of reinforcing fiber materials in a mold to form a reinforcing fiber material laminate, and impregnating a resin into said reinforcing fiber material laminate by injecting a resin in a direction from an end surface of said reinforcing fiber material laminate along a laminate surface while reducing pressure in said mold by evacuation. |

1. A method of RTM molding comprising:
laminating a plurality of reinforcing fiber materials in a mold covered with a bag material to form a reinforcing fiber material laminate comprising a part that forms a stringer material having a section of a rectangular, C-type, I-type, L-type, Z-type, T-type, J-type or hat shape, and a part that forms a skin material, and impregnating a resin into said reinforcing fiber material laminate by injecting a resin through a resin distribution medium with a resin flow resistance 1/10 or less than a resin flow resistance in the reinforcing fiber material laminate and located at an end surface of said reinforcing fiber material laminate and then in a direction along a laminate surface while reducing pressure in said mold by evacuation, wherein said resin is injected from an end surface of said part that forms a stringer material of said laminate mainly into a portion between layers of said reinforcing fiber materials, then the injected resin is impregnated into the entire part that forms a stringer material. |
