Hi guys. I am currently doing a research on the use of thermoplastic fibers as reinforcement, which is a relatively new idea. Fiber reinforced polymer (either thermoset or thermoplastics) composites can be tailored to meet different requirements and applications by customizing. Thermoplastics generally offer better impact resistance compared to thermosets. My studies will be to test the properties of a composite composed of polymer matrix and thermoplastic fabric reinforcement. Usually, for thermoplastic composites, the thermoplastic component comes from the matrix or resin, whereas the fiber can be carbon. But i am trying to explore the use of thermoplastic fiber as reinforcement instead. 

Is there any recommendation for me to start? is there any thermoplastic fiber that i can consider to use in my composite? in this composite, what kind of matrix (thermoplastic or thermoset) will be best for my composite.

I'm with Lester,thermoplastic fibres have been around and used in composites for a long time, there are lots of companies producing composite panels with Dyneema and Innegra as well as hybrid composites consisting of those fibres woven together with other reinforcements like carbon and fibreglass. 

If you are looking for suggestions, Innegra is probably going to be the easiest thermoplastic fibre to source, and you can get it in a whole bunch of different configurations. And for your matrix, epoxy is generally the highest performing thermoset resin for most applications. If you are looking for impact strength, you might also consider a phenolic. Vinyl ester might be ok, but is generally a lower performing resin than epoxy. Polyester would be a poor choice.

Resin infusion is probably going to be your best production method, given its versatility and high performance.
