Abstract:
A cellulose-based natural fiber is added to an injection-molded plastic part, especially a fitting for the interior of a motor vehicle. In this manner, the strength of the part is increased and the fibers do not show on the surface.
Abstract:
Disclosed is a spun yarn for a fiber-reinforced plastic, which is composed of blended yarns (3a, 3b) of a natural plant fiber and a synthetic fiber. The synthetic fiber is a thermoplastic synthetic fiber capable of serving as a matrix resin in a FRP. Also disclosed is an intermediate for a fiber-reinforced plastic that is a woven fabric, a knitted fabric, a multiaxial warp knitted fabric or a braided fabric, formed of the aforementioned spun yarn for a fiber-reinforced plastic. Also disclosed is a fiber-reinforced plastic molded article that is obtained by heating and press-molding the intermediate for a fiber-reinforced plastic at a mold temperature equal to or higher than the melting point of the synthetic fiber, or by aligning the spun yarn for a fiber-reinforced plastic in at least one direction, heating and press-molding the same at a mold temperature equal to or higher than the melting point of the synthetic fiber. Thus, the spun yarn for a fiber-reinforced plastic that exhibits superior integrity between the natural plant fiber and the synthetic fiber and that also a good moldability can be obtained at a low cost. And furthermore, the intermediate and the fiber-reinforced plastic molded article using the same can be provided.
Abstract:
A nonwoven trough (12) and method of construction thereof are provided. The nonwoven trough includes at least one nonwoven wall (14) formed from a mixture of bonded natural cellulosic fibers and thermoplastic fibers. The at least one nonwoven wall extends along a longitudinal axis (19) and has a midsection (18) and opposite end portions (20, 20'). The midsection has a base (22) and a pair of walls extending upwardly from the base to provide the midsection with a generally U-shaped cross-section taken generally transversely to the longitudinal axis. At least one flange (30) extends laterally from the at least one nonwoven wall, wherein the flange is configured for attachment to a vehicle member.
