三维编织碳纤维/环氧树脂复合材料横向压缩性质的温度效应
|
Abstract:
采用实验和有限元方法，研究了三维编织碳纤维/环氧树脂复合材料在低温场（20、0、-50、-100℃）中横向压缩性质温度效应。研究结果表明：温度对碳纤维/环氧树脂横向压缩模量、屈服应力及切向模量均有不同程度影响。三维编织碳纤维/环氧树脂复合材料横向压缩后，试样表面形貌受温度影响显著。低温场中，表面鳞纹现象减弱，且纱线-树脂间界面出现开裂。温度降低导致碳纤维/环氧树脂内部产生热应力。热应力对碳纤维/环氧树脂力学性能影响有限，不是温度效应的主导因素。基体性质随温度变化是三维编织碳纤维/环氧树脂复合材料横向压缩性质温度效应的主要机制。 The temperature effect on transverse compressive behaviors of 3D braided carbon fiber/epoxy composites was investigated in low temperature fields (20, 0, -50, -100℃). The experiments were performed and the finite element method was adopted. The results indicate that the temperature has influence on the transverse compressive modulus, yield stress and tangent modulus of 3D braided carbon fiber/epoxy composites at different levels. The surface morphologies of 3D braided carbon fiber/epoxy composites after transverse compression are also influenced by temperature significantly. At low temperature, the surface scaly pattern of 3D braided carbon fiber/epoxy composites reduces and the yarn-matrix interfacial crack occurs. The temperature reduction gives rise to the internal thermal stress, but the thermal stress has a limited influence on the mechanical behavior and is not the main factor in temperature effect. The property variation of epoxy matrix with temperature is the main mechanism for the temperature effect on transverse compression of 3D braided carbon fiber/epoxy composites. 国家自然科学基金（51675095）
