Abstract (en)
Textile material contains hybrid yarn of polyester reinforcing fibres and low-melting polyester matrix fibres and has a density D > 0.6 g/cm<3>, in which D = the ratio of the mass/unit area in g/cm<2> and the thickness in cm. Also claimed is a method of making composites from this material.
