T he m ech anical properties and hydrotherm al stability of the resin and it s T 800 carbon f iber composite w ere analyzed too. T he result show ed the resin matrix has a low v iscosity. It can be used as the m atrix of T 800 carbo n fiber composite fo r w et w inding. T he interlam inar shear streng th of the composite can g et to 101 M Pa and tensile strength of N OL r ing can reach up to 2500 M Pa. When being imm ersed in the distilled w ater at 95 fo r 150h , equilibrium moisture content of the composite is low er th an 1% and the mechanical prop erties retention is high. So it is proved to process ex cellent interfacial pro per ty and hydrotherm al stability f or the composite. Key words w et w inding , T 800 carbon f iber, composite
