Manufacturing and properties of r-PETG/PET fibre

2018-12-1  The study proposes utilisation of recycled PETG foils as a matrix for manufacturing of a composite reinforced with short PET fibres. With 70/30 wt-% filling ratio its notched impact strength of ∼12.8 kJ/m 2 is twice higher than native PETG, 6-fold higher than the r-PETG and on the level of PP reinforced with the same content of glass fibres. Its good mechanical properties allow it to be ...
