中文摘要 | 本研究以纏繞成型法製造混纖複合材料管,將克維拉(kevlar)纖維以三種角度纏繞夾於90°之碳纖維,或玻璃纖維層之間。製作完成,以落重式衝擊試驗機來評估管之抗衝擊性能,並探討其破壞模式,及混纖型式、管厚對衝擊性能的影響。玻纖-克維拉-玻纖疊層之混纖管比碳纖-克維拉-碳纖管有較高之衝擊性能。衝擊性能隨管厚之增加而增加,但並非線性關係,而與中間克維拉纖維層的纏繞角度有關。當克維拉纖維層的角度為60°,其增加量最大。碳纖-克維拉-碳纖[90° 2/±60° 2/90° 2]的衝擊能量是碳纖-克維拉-碳纖[90° /±60° /90° ]的3.44倍,但厚度僅是2倍。玻纖-克維拉-玻纖管在厚度方向主要的破壞模式是層內破壞及克維拉纖維的細化;而碳纖-克維拉-碳纖管的主要破壞模式是脫層及貫穿。 |
英文摘要 | Hybrid composite tubes were filament wound with Kevlar fibers under three winding angles and sandwiched by either hoop carbon or glass fibers. The tubes were subjected to impact using a drop-weight impact apparatus with a round-ended impactor. Impact energies (resistance) of the tubes were measured and their damage modes through the thickness were proposed. In addition, the influence of tube thickness and hybrid type on the impact resistance was also investigated. GKG (glass-Kevlar-glass) hybrid tubes have higher impact resistance than that of CKC (carbon-Kevlar-carbon) hybrid tubes. The impact energy increases non-linearly with tube thickness, and depends on winding angle of Kevlar layers. When the winding angle of Kevlar layer is 60o, the increase is largest. The impact energy of CKC [90o2/±60o2/90o2] tube (8 layers, 2.29mm in thickness) is 3.44 times that of CKC [90o/±60o/90o] tube (4 layers, 1.16mm in thickness). Major damage modes for GKG tubes through-thickness are intralaminar fracture and Kevlar fiber fibrillation; while major damage modes for CKC tubes are delamination and penetration. |
