Abstract

Highlights: Quantitative impact characterisation of textile reinforced cementitious laminates (TRC). Master curves, energy-time curves and energy profiles are obtained following the energy profiling method. Similar drop weight impact response to polymer matrix composites is verified. Effect of laminate thickness and impactor diameter is studied. Abstract: This work presents the characterisation of the local low velocity impact behaviour of a high-performance fibre reinforced cementitious composite (HPFRCC) made of phosphate cement and different types of E-glass textile reinforcements. The so called "energy profiling method" that was used for quantitative characterisation is adopted from Liu et al. (2004) who introduced this methodology on polymer matrix composites (PMC). A series of plates reinforced with chopped strand E-glass fibre mats (fibre volume fraction of 24%) was impacted during drop weight tests, showing that this methodology is as well applicable to textile reinforced cementitious composites. Further, the effects of impactor size and plate thickness were investigated experimentally, and finally the obtained results were compared to literature data for polymer matrix composites.
