摘要： The present invention concerns glass fibre composition comprising the following oxides : Si0
2 : 57.5- 59.5 wt.% AI
2 O
3 : 1 7.0-20.0 wt.% CaO: 1 1.0-1 3.5 wt.% MgO: 8.5 - 1 2.5 wt.% wherein the sum of Na
2 O, K
2 O, and TiO
2 is at least 0.1 wt.% and Li
2 O ≤ 2.0 wt.%, all amounts being expressed in weight % with respect to the total weight of the composition. It also concerns composite materials reinforced with such fibres, used in applications such as windmill blades, pressure vessels, components in the automotive, machinery, aerospace applications and such products produced therewith, and wherein the temperature difference, ΔΤ, defined as the difference between the temperature, T3, at which the composition has a viscosity of 10
3 Poise and the liquidus temperature, T
liq , is at least 50°C.
