Drilling of carbon fibre reinforced plastic composites
… survey focusing on the machinability of carbon fibre reinforced plastics (CFRP), three main phases of experimental work were undertaken to evaluate the drilling of CFRP and associated stack materials. Phase 1 and 2 involved small diameter holes (1.5 mm) in thin CFRP laminates (3 mm thick) while …

Investigation of strain rate sensitivity of polymer matrix composites
… by developing a finite element model for a fibre reinforced polymer (FRP) plates impacted at varying strain rates. The work was divided into three facets, firstly to characterize the FRP material at varying strain rates, to develop a constitutive model to elucidate the relationship between …

Multi-axial strain monitoring of fibre reinforced thermosetting plastics using embedded highly birefringent optical fibre Bragg sensors
There is a growing interest in the use of fibre reinforced plastics (FRPs) as high-grade construction material for variouw applications that need to be lightweight, yet strong in sometimes harsh loading conditions. Despite the growing popularity of structural composite materials, one has to realize …

Strengthening prestressed beams using parafil ropes as external tendons
… problem that faced this type of strengthening, Fibre Reinforced Plastics (FRP) can be used instead of steel tendons. Within the different types of FRP, Parafil rope was established to be well suited for prestressing system, combining the benefits of light-weight, high strength, easy handling and …
