摘要/Abstract

摘要： 帽形加筋壁板具有高比强度、高比刚度、良好的可设计性等优点,在航空航天、能源交通、海洋工程、医疗、建筑、机械等工程领域得到了广泛应用。本文分析了固化工艺参数(固化温度、固化压力、降温速率)对帽形加筋壁板固化变形的基本规律,在深入研究预浸料固化动力学的基础上建立了帽形加筋壁板固化变形的理论模型。通过实验对该模型进行了验证和修正,修正后的理论模型与实际变形量具有较好的一致性。

Abstract: Cap-shaped stiffened composite panels are widely used in the fields of aerospace,energy,traffic,ocean engineering,medical,building,machinery engineering and so on because of its special properties such as high strength,high stiffness to weight ratio and design flexibility. During their manufacturing processes,however,thermo- curing inherently produces the undesired residual stresses and cure deformations,which limits the applications of composite structures in a certain degree. In order to reduce the cure deformation,the effect of curing parameters (curing temperature,curing pressure,cooling rate) on the deformation of composite cap-shaped stiffened composite panels is discussed in this paper. A simple mathematical model based on the curing dynamics is built for the deformation of the cap-shaped stiffened composite panels. The deformation calculated by the mathematical model and experimental results are compared,and an error correction model is established. The error correction model shows a good agreement on the experimental results.

Key words: cure cycle, process-induced deformation, mathematical model
