Sustainability Characteristics of Damaged Carbon Fiber Composites
Main Article Content
Abstract
Usage of composites has increased in many fields of application ranging from space to repair and rehabilitation. Damage of composites in the form of cracking or de-lamination is quite common during its life. Performance of the composites after damage with or without repair is an indicator to one of its sustainability aspects. Here in this study, the damage parameter from the point of cracking is studied beyond normal yield considerations using inelastic material model to assess its remaining life. It is observed that, based on the load quantity of damage occurrence, sustainability is measured as life cycle analysis in terms of remaining life that can change significantly if one accounts for inelastic material behaviour.
