摘要

本工作的目的是研究粘结台阶和围巾修复方法对玻璃纤维-环氧树脂复合材料拉伸强度恢复的影响。复合材料采用手工叠层技术制造，试样在41J和44.3J的两种不同能量下受到冲击。使用染料渗透和CAD图像缩放技术评估损伤。损伤修复试样的特征在于拉伸试验，该试验在具有与母体层压板相同修复的板的切割部分上进行。对于41 J和44.3 J的冲击能量，围巾修复层压板的拉伸强度恢复率分别为69.26%和64.19%，而对于阶梯修复层压板，其拉伸强度恢复度分别为63.46%和59.74%。

Effect of bonded stepped and scarf repair on impact damaged glass fibre reinforced polymer composite properties

The objective of the present work is to investigate the effect of bonded stepped and scarf repair methods on the tensile strength restoration of glass fibre epoxy composites. The composites were fabricated using hand lay-up technique and the specimens were subjected to impact at two different energies of 41 J and 44.3 J. The damage was assessed using dye penetration along with CAD image scaling technique. Damage repaired specimens were characterised for the tensile test which was carried out on a cut portion of the plate having repair identical to the parent laminate. Tensile strength restoration for 41 J and 44.3 J impact energies of scarf repaired laminates was 69.26% and 64.19%, respectively, whereas for step repaired laminates it was 63.46% and 59.74% respectively.
