中文摘要 | 本文探討在複合材料積層板加工程序(如壓熱釜成型、真空袋成型)中,纖維與樹脂的細部結構變化。我們假設複合材料積層板含多層單方向纖維,且具有任意不規則之排列方式,並以波浪型渠道來模擬樹脂在纖維間的流動形態。樹脂在纖維上的作用力可分為與流動同向的摩擦力,及由纖維擠壓引起的層間壓力。二者並分別由不同的渠道模式來代表。模擬結果除描述纖維與樹脂共固化過程中複合材料結構以及內部應力的變化外,也討論了預浸材結構以及操作溫度的影響。 |
英文摘要 | The infrastructure of a fiber-resin ply in laminate processing by autoclave/vacuum bag forming was studied. The consolidation of unidirectional fibers as well as corresponding resin flow were simulated numerically. A system of undulating channels was used to describe the unidirectional fiber arrays which do not have regular geometric arrangement. The forces acting on the fibers were discriminated into a shear force due to resin flow and a hydrodynamic squeezing force caused by fiber compactness. Continuously varying structure of the fiber bed as monitored. Effects of the initial structure of the ply and controlled temperature ramping are also reported. |
