摘 要 本文針對含中心孔洞和含多孔復合材料結(jié)構(gòu)模型，利用Fibersim進行鋪層設(shè)計并檢驗鋪層角度是否偏差，對于含中心孔洞復合材料結(jié)構(gòu)采用分區(qū)域鋪覆的設(shè)計方法進行探究，發(fā)現(xiàn)可以達到在制造中節(jié)省材料成本的作用。將兩種結(jié)構(gòu)進行仿真失效計算同時與不開孔狀態(tài)的復合材料結(jié)構(gòu)進行比較，得出失效比值。

ABSTRACT In this paper， we use Fibersim to design the lay-up for center hole and porous composite structure model， check whether the layup angle is deviated or not， and explore the design method of lay-up by area for center pore composite structures， and find that it can achieve the role of saving the material cost in manufacturing. The two structures were subjected to simulated failure calculations while comparing them with the composite structure in the unopened state to derive the failure ratio.
