The present invention relates to a cushion flooring material and a manufacturing method for the same and, more particularly, to a cushion flooring material and a manufacturing method for the same, which uses an elastic layer including a PHA resin alone or a composite resin including a PHA resin as a surface layer constituting the cushion flooring material to prevent toxic substances exposed to the user even if the surface layer is exposed due to wear of a surface treatment layer positioned on the surface layer, thereby making the cushion flooring material non-toxic, eco-friendly and excellent in sound insulation.

The following configuration is adopted for the purpose of solving reduction in strength and rigidity at a weldline which is a problem of an injection molding body, and enabling free design such as thin wall molding or complex shape molding of the injection molding body. That is, there is provided an integrally molded body in which a substrate for reinforcement (a) having a discontinuous fiber (a1) and a resin (a2) and an injection molding body (b) having a discontinuous fiber (b1) and a resin (b2) are integrated, the substrate for reinforcement (a) covering a part or all of a weldline of the injection molding body (b) to be integrated with the injection molding body (b), the ratio of thickness Ta of the substrate for reinforcement (a) to thickness T of a weldline part of the integrally molded body satisfying relational expression: in a case of Ea≠Ebw,
Ta/T≤((Ebw−√(Ea.Math.Ebw))/(Ebw−Ea)) in a case of Ea=Ebw,
Ta/T≤0.5 wherein, Ta: Thickness of substrate for reinforcement (a), T: Thickness of weldline part of integrally molded body, Ea: Flexural modulus of substrate for reinforcement (a) in width direction of weldline, and Ebw: Flexural modulus of weldline of injection molding body (b) in width direction of weldline.

A method of forming an elongated composite element includes providing an elongated tubular member and establishing a plurality of holes through an outer wall of the elongated tubular member. A polymeric resin is provided that comprises a curable material that, when uncured, comprises a fluid material and that, when cured, comprises a substantially rigid material. The uncured polymeric resin is extruded along the elongated tubular member, whereby the polymeric resin flows at least partially through the holes and is disposed within the inner cavity and at an outer surface of the outer wall of the elongated tubular member. The polymeric resin is cured to form the composite element whereby the cured polymeric resin limits flexing of the at least one elongated tubular member and the elongated composite element.
