Sound absorbing component

An acoustic absorbing component comprising a fiber-reinforced thermoplastic resin expanded body having a percentage of void not less than 50 vol %, and a resin molded body. The fiber-reinforced thermoplastic resin expanded body is fused under a pressure to at least a part of a surface of said resin molded body.

Acoustic absorbing component and production process thereof

A method for producing a fiber-reinforced thermoplastic resin molded article laminated with a skin material comprises the steps of: providing a mold assembly including a first mold and a second mold; preheating a fiber-reinforced thermoplastic resin sheet; preheating a skin material; supplying the preheated sheet and skin material to between the molds; drawing the preheated skin material under reduced pressure so as to bring the skin material into close contact with a cavity face of the second mold; and moving the molds so as to attain a closed state thereby laminating the sheet and skin material together.

Method for producing fiber-reinforced thermoplastic resin molded article

Paper-made stampable sheet, light-weight stampable sheet shaped body and

A fiber-reinforced article includes an expanded core layer having opposing first and second surfaces with a thickness defined therebetween. The expanded core layer is formed from a composition comprising a thermoplastic material and fibers with average length of not less than about 1 mm, with at least a portion of the fibers being coated with the thermoplastic material. The fibers collectively define a network structure in which the fibers are interconnected with each other and fixed relative to each other via the thermoplastic material so that the coated fibers define interstitial voids therebetween. The article further includes first and second skin layers, the first skin layer having a surface integrally connected to the first surface of the expanded core layer and the second skin layer having a surface integrally connected to the second surface of the expanded core layer.

Fiber-reinforced article and a method for producing the same

A mold assembly for producing a fiber-reinforced thermoplastic resin molded article laminated with a skin material comprises: a first mold having a first cavity face; a second mold having an indentation whose bottom surface forms a second cavity face; a driving unit for reciprocating the mold connected thereto; and a cutting blade, attached to the first mold, having a cutting edge opposed to the second cavity face of the second mold, the cutting edge being relatively moved, at closing operation, along an inner peripheral side surface of the second mold with a predetermined clearance with respect to the inner peripheral side surface.

Mold assembly for producing fiber-reinforced thermoplastic resin molded

A multilayer molded article includes a resin body and skin material with good quality and is produced by a process which includes the steps of: (a) supplying a skin material between a male mold and a female mold which are attached to a clamping mechanism, (b) starting closing of the male and female molds, and supplying a resin melt for the resin body between the skin material and the male or female mold while temporarily stopping the closing action of the mold or adjusting a closing rate at 30 mm/sec. or less when a cavity clearance between the molds is in the range between (C+100) mm and (C+5) mm (wherein C is the cavity clearance when the molding is finished), and (c) further closing the molds to the cavity clearance of C to finish the molding.

Process for producing a multilayer molded article

A multilayer molded article having improved appearance and feeling is produced by wetting a skin material including a fabric or a thermoplastic resin sheet as an outermost layer with at least one liquid material which is water, an aqueous solution, a volatile material which is liquid in an ordinary state, or a solution including the volatile material as a medium, supplying the wet skin material between male and female molds, supplying a thermoplastic resin melt between the molds and closing the molds to form the multilayer molded article including the integrally adhered skin material and the thermoplastic resin.
