Claims
- 1. A chopped strand mat comprising chopped strands having fiber lengths of 10 to 100 mm and doped with a surface treating composition containing 0.05 to 2.0 weight percent of an epoxysilane coupling agent and 0.2 to 2.0 weight percent of an epoxy resin and, bound with 0.5 to 10 weight percent of a mat binder of a polymer containing an acrylic ester unit.
- 2. The chopped strand mat of claim 1 wherein said chopped strands are made of at least one member selected from the group consisting of glass fiber, wholly aromatic polyester fiber and carbon fiber.
- 3. The chopped strand mat of claim 1 or 2 wherein said polymer is a polymer of at least one monomer selected from the group consisting of acrylic acid esters and methacrylic acid esters.
- 4. A thermoplastic sheet comprising 15 to 60 weight percent of a chopped strand mat impregnated with a thermoplastic resin, said chopped strand mat comprising chopped strands having fiber lengths of 10 to 100 mm and doped with a surface treating composition containing 0.05 to 2.0 weight percent of an epoxysilane coupling agent and 0.2 to 2.0 weight percent of an epoxy resin and, bound with 0.5 to 10 weight percent of a mat binder of a polymer containing an acrylic ester unit.
- 5. The thermoplastic sheet of claim 4 wherein said thermoplastic resin is at least one member selected from the group consisting of polyolefin resin, polyester resin, polyamide resin, polyethersulphone resin and polycarbonate resin.
- 6. The thermoplastic sheet of claim 4 or 5 wherein said thermoplastic resin is polyolefin resin.
- 7. The thermoplastic sheet of claim 6 wherein said polyolefin resin is polypropylene.
- 8. The thermoplastic sheet of claim 4 or 5 wherein said thermoplastic resin is polyester resin.
- 9. The thermoplastic sheet of claim 8 wherein said polyester resin is polyethylene terephthalate.
- 10. The thermoplastic sheet of claim 4 for stamp-molding.
