Fastener joint for composite material

摘要: PURPOSE:To improve the strength of a fastener joint by increasing elongation material or end hole as compared with that other section and decreasing its rigidity section. CONSTITUTION:As A, having larger smaller than those (outer section) is employed. For example, carbon fiber composite employed outer section, glass material, aramid etc., A. Thus, uniform load region for sharing surface pressure to be transmitted can separated. That is, transferred shearing high rigid region, may share only without load, thereby improving stress concentration.
