Abstract
A molding material comprises at least the following components A, B and C, with the component C arranged to contact a composite comprising the components A plus B. The components are elongated members identified as: A A continuous reinforcing fiber bundle, B A thermoplastic polymer or oligomer having a weight average molecular weight of 200 to 50,000 and a melt viscosity lower than that of the component C, and C A thermoplastic resin having a weight average molecular weight of 10,000 or more.
Claims35
A molding material comprising a composite A+B contacted to a component C, said composite comprising a continuous reinforcing fiber bundle A dispersed in a thermoplastic polymer B or oligomer B having a weight average molecular weight of 200 to 50,000 and a thermoplastic resin C intimately adhered to said composite A+B;
- wherein said resin C has a predetermined melt viscosity and a weight average molecular weight of 10,000 or more, and wherein said thermoplastic polymer B or oligomer B has a melt viscosity that is lower than said melt viscosity of said thermoplastic resin C.
