内容記述タイプ | Abstract | |||||
内容記述 | この報告はCFRP(炭素繊維強化プラスチック)複合材積層板の圧縮強度に及ぼす衝撃荷重の影響について述べた。積層板は衝撃損傷を与えた後、残留強度を評価するために圧縮荷重を負荷した。衝撃による積層板内部の損傷状態は超音波探傷検査および実体顕微鏡を用いて調べた。試験結果の概要は次のようである。積層板内部の層間剥離面積は衝撃面より裏面の方が大きく、その剥離面積の形は最外積層方向を長軸とする楕円形を示した。また、剥離面積の大きさと衝撃エネルギーはほぼ比例関係にあった。衝撃損傷による圧縮残留強度は衝撃エネルギーの増大によって低下を示し、70J/cmの衝撃損傷を受けた場合の圧縮残留強度は衝撃を受けない場合の約70%の強度に低下した。 | |||||

内容記述 | This report describes the influence of impact damage on the compressive strength of CFRP (Carbon Fiber Reinforced Plastics) -laminated panels. The panels with impact damage are subjected to compressive loads for evaluation of their residual strength. The interlaminar failure of the panels with impact damage is investigated using ultrasonic inspection techniques and optical microscopy. The test results are summarized as follows. The area of delamination on the reverse surface is larger than that on the impact surface. The shape of the area is an ellipse whose major axis corresponds to the fiber direction of the surface laminate. In addition, the area size is approximately proportional to the impact energy. The compressive residual strength decreased with increasing impact damage. The compressive residual strength with impact damage of 70 J/cm is reduced to about 75 percent of the strength without impact damage. | |||||
