A New Self Healing Method in Composite Laminates Using the Hollow Glass Fiber
The purpose of the present study is to obtain the least strength reduction and uttermost healing efficiency in a typical [(90/0)/(90/0)Hollow/90/(0/90) Hollow/90/(0/90) Hollow/(0/90)] self-healing laminate. It has been done using a hollow glass fiber (HGF) with a given diameter and an individual method to distribute the HGF in the host laminate. The results of three-point bend flexural strength testing indicated that for the investigated distribution, the inclusion of HGF imparts little reduction in undamaged strength (4%) which is due to the non-integrity of self-healing laminate related to the host laminate. After healing it was found that the laminate had a residual strength of 97% compared to the undamaged control and 100% compared to an undamaged self healing laminate.
