CARBON FIBER PREPREG AND METHOD OF PRODUCTION THEREOF

A carbon fiber prepreg is produced by impregnating a carbon fiber bundle comprising a large number of continuous carbon filaments and having a degree of intermingle of at least 10 cm as a hook drop value with a base resin containing a thermosetting resin as a principal component. Not greater than 20 wt.%, on the basis of the weight of the total prepreg, of particles of a thermoplastic resin having a particle size of not greater than 150 'mu'm are distributed at a higher concentration in the surface region than in the inside. This carbon fiber prepreg has a high tack which little changes with time. The prepreg makes it possible to mold a composite having excellent compression inter-layer shear strength (CILS) at high temperatures after having absorbed moisture while maintaining a good impact resistance and to obtain a composite having a by far higher compression strength (LCS) of a cross-laminated sheet than those of existing composites.

Prepreg sheets and prepreg stacks useful for preparing low void content fiber-reinforced compostite materials

The void content of a cured fiber-reinforced composite material is advantageously reduced, particularly when the composite material article is large in size or fabricated using an out-of-autoclave procedure, by using prepreg sheets impregnated with a thermosettable resin composition containing thermoplastic particles and modified to have one or more characteristics such as a certain level of average surface roughness. Such characteristics may be imparted to the prepreg sheet by, for example, conditioning the prepreg sheet by subjecting it to vacuum conditions in advance of being consolidated and cured as part of a prepreg stack.

Prepreg, prepreg laminate, and fiber-reinforced composite material

The purpose of the present invention is to provide: a prepreg which is suitable for producing a fiber-reinforced composite material in a short period of time without using an autoclave, can produce a fiber-reinforced composite material in which the occurrence of voids is suppressed and excellent impact resistance is achieved, and has excellent handling properties; and a fiber-reinforced composite material using the prepreg. This prepreg is a prepreg in which a reinforcing fiber [A] arranged in layers is partially impregnated with an epoxy resin composition containing an epoxy resin [B] and a curing agent [C], wherein the impregnation rate φ is 30-95%, and a thermoplastic resin [D] insoluble in the epoxy resin [B] is unevenly distributed on both surfaces of the prepreg. In addition, in the layers of the reinforcing fiber [A], epoxy resin composition-unimpregnated portions are localized on one surface of the prepreg, and the localization parameter σ, which defines the degree of localization, is in the range of 0.10<σ<0.45.
