Molded article of composite resin containing fibers
In a method producing a molded article of a composite resin containing base resin and fibers, the composite resin containing a fibrous filler in the base resin and the fibrous filler including natural fibers with a fibrillated part on each end of the fibrous filler in a fiber length direction, the base resin and the fibrous filler are charged into a melt-kneading device. The base resin is melted and the molten base resin and the fibrous filler are kneaded in the melt-kneading device, thereby fibrillating only the ends of the fibrous filler. The obtained composite resin is discharged from the melt-kneading device and formed into a pellet shape, with the molded article of the composite resin produced by molding the pellets.
Selective placement of advanced composites in extruded articles and building components
Embodiments herein include extruded articles, building components and methods of making the same. In an embodiment, an extruded article is included. The extruded article can include a body member including a first portion comprising a first composition, the first composition comprising a polymer resin. The extruded body member can also include a second portion comprising a second composition different than the first composition. The second composition can include a polymer resin, fibers, and at least one component selected from the group consisting of at least 1% by weight particles and at least 5 phr impact modifier. Other embodiments are also included herein.
Method and system for forming a composite material
A method of forming a composite material includes mixing granules of thermoplastic(s) and granules of reinforcing material(s) using a mixer with an interior friction coating. The friction generated by interaction between the granules and friction coating causes granules of at least one of the thermoplastic(s) to be heated to a liquid or semi-liquid state. The liquid/semi-liquid thermoplastic(s) act a binder for the mixed material. A system for forming such a composite material includes such a mixer with an interior friction coating. The system may also include a mould and/or a press for forming material produced by the mixer into a finished shape. The method and system may use post-consumer and post-industrial material as an input allowing such material to be recycled. In some cases, cross-contaminated or mixed post-consumer/post-industrial material may be recycled, potentially reducing environmental impacts.
Reinforced clinical waste container comprising wood fibres and method for producing the same
Clinical waste container (100) comprising a lower basket part (110) and an upper lid part (120), comprising a cylindrical part (121) having an upper lid opening (122); and a lid cap part (130), arranged to be fastened to said lid part so as to cover said lid opening, wherein the lid part and the lid cap part each comprise cooperating snap-lock means (123, 133), comprising several separated elongated protrusions (133a,133b), together defining a broken circle.
