Abstract(J)カーボンの破壊データは最終破断値のみ述べられる事が多く、負荷中の健全性を評価する例は少ない。本稿では、カーボンの長繊維であるC-SMCにAE法を適用し、ASMEで用いられている健全指標を試験片の引張試験下、及びボデー構造試験下に取り入れ、評価した結果を報告する。

Abstract(E)C-SMC (Carbon fiber - Sheet Molding Compound) is formed by mixing carbon fiber with a long fiber and resin. The fiber distribution becomes uneven in the part due to the resin flow during manufacturing. Therefore, it is more difficult to grasp the signs at the time of fracture and the growth of cracks than other CFRPs. In this paper, we performed C-SMC tensile strength test and C-SMC structural component test with loading / unloading cycles by acoustic emission and reported the result of evaluation and application of Kaiser effect for C-SMC.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
