I have tried to slow down my printing speed sadly this seems to have no effect and im having absolutely no problems with feeding the problems seem to be coming from the infill not working correctly

So I'm having a problem printing one material. I'm printing in colorfabbs XT carbon fibre varient. Using a steel nozzle and slicing with simplify3D and no matter what I try I get infill problems. The infill is like thin whisps. The base layers come out looking beautiful and the only two things that have changed since I introduced this material is the fact I changed the nozzle and the material.

Please help I've been trying for days and no luck thank you for any input
