摘要:
In one aspect, the present invention provides a cured composite composition comprising (a) a fiber component; and (b) an organic composition. The organic composition comprises a cured epoxy continuous phase and a nanoparticulate thermoplastic block copolymeric discontinuous phase. The nanoparticulate thermoplastic block copolymeric discontinuous phase has a domain size distribution in a range from about 1 nanometer to about 500 nanometers, and the discontinuous phase is substantially uniformly distributed throughout the cured composite composition. Articles and method of making the cured composite compositions are also provided.

In one embodiment, the present invention provides a preform. The preform includes (a) a reinforcing fabric layer; and (b) a thermoplastic block copolymer fiber incorporated into the reinforcing fabric layer. The thermoplastic block copolymer includes methylmethacrylate structural units and is substantially soluble in an uncured epoxy resin and substantially insoluble in a corresponding cured epoxy resin. An uncured composite composition, a cured composite, and a method of making the cured composite are also provided.

A UV curing system 130 and method 150 for manufacture and repair of composite parts, such as for use in wind blade manufacture and repair is disclosed. The system 130 and method 150 utilize UV as the single radiation source to cure laminates 112 such as glass fiber reinforced laminates containing a photo initiator. The use of Co naphthenate or phenoxyethyl methacrylate in the curing of thick laminates 112 produces high glass transition and complete curing of thick laminates 112. The addition of cobalt naphthenate and phenoxyethyl methacrylate shows no significant reduction on the bonding strength.

In one embodiment, the present invention provides an uncured composite composition. The uncured composite composition includes an uncured resin and a triaxial braid. The triaxial braid includes a longitudinal axis, a first bias fiber extending in a first bias direction at a first bias angle to the longitudinal axis, a second bias fiber extending in a second bias direction at a second bias angle to the longitudinal axis, and an axial fiber extending in a direction parallel to the longitudinal axis; wherein the first bias fiber, the second bias fiber, and the axial fiber have a substantially same tow size, and the tow size is in a range of from about 1k to about 11k. A cured composite and a method of making the cured composite are also provided.
