Webs， stampable sheets， and expansion molded products

In addition to excellent sound-absorbing properties and rigidity， there are provided an expansion molded article that is difficult to tear after bending deformation， and a web and stampable sheet suitable for manufacturing the expansion molded article. The web， stampable sheet， and expansion molded article of the present invention are webs， stampable sheets， and expansion molded articles containing reinforcing fibers including inorganic fibers and organic fibers， a thermoplastic resin， and heat expandable particles， and The ratio is 20% by mass or more and 55% by mass or less with respect to the total amount of the reinforcing fiber and the thermoplastic resin， and the ratio of the organic fiber is 25% by mass or more and 77% by mass or less based on the total amount of the organic fiber and the inorganic fiber， The average length is 8 mm or more， and the elongation at break of the organic fiber is 15% or more. Provided are: an expansion-molded product which is not only excellent in sound absorption and rigidity， but also resistant to tearing after bending deformation; and a web and a stampable sheet which are suitable for producing the expansion-molded product. The web， stampable sheet， and expansion-molded product of the present invention contain: reinforcing fibers including inorganic fibers and organic fibers; a thermoplastic resin; and thermally expandable particles， wherein the proportion of the reinforcing fibers is 20-55 mass% with respect to the total amount of the reinforcing fibers and the thermoplastic resin， the proportion of the organic fibers is 25-77 mass% with respect to the total amount of the organic fibers and the inorganic fibers， the average length of the reinforcing fibers is at least 8 mm， and the breaking elongation of the organic fibers is at least 15%.
