ABSTRACT:
Reinforcing fiber materials such as rovings, webbings, and other fiber maials are impregnated with a resinous binder material in such a manner that gaseous inclusions are avoided whereby a surprising increase in the strength of the fiber compound material is achieved. For this purpose the liquid resinous binder material is applied substantially only to one side of the reinforcing material which is then moved through an absorbing zone in which the liquid resinous binder material penetrates the reinforcing material substantially completely as a result of a predetermined residence time and temperature in the absorbing zone. Gas inclusions are removed by adsorption and/or by expulsion. The gas adsorbing and expulsion zone is a chamber in which a plurality of guide rollers are arranged so as to cause the impregnated material to repeatedly reverse its moving direction, whereby the sequential and repeated penetration of the reinforcing material by the resinous material and the removal of gas inclusions are enhanced. Further, the precise weight ratio adjustment of resin to fiber material is enhanced by moving the impregnated material in a substantially vertical orientation through a fulling station. The vertical orientation facilitates the flow off of excess resin.
