An outer skin component for a motor vehicle is designed as a shell component with an outer shell and an inner shell, which are in each case designed as fiber-reinforced plastics shells with a fiber reinforcement embedded into a thermosetting plastic matrix. The fiber reinforcement of the outer shell consists of one or more layers of nonwoven material.

A composite oil pan for a work vehicle engine and a method of forming the composite engine oil pan include forming a sheet of metal into a first pan and open molding a fiber-reinforced polymer resin onto the first pan forming a second pan. The first pan has a first bottom wall and first peripheral walls extending from edges of the first bottom wall to define a sump, the first peripheral walls terminating in a first peripheral flange. The second pan has a second bottom wall and second peripheral walls abutting the first bottom wall and the first peripheral walls, the second peripheral walls terminating in a second peripheral flange. The first pan defines a thin metal structure with an inner surface extending across the first bottom wall, first peripheral walls and first peripheral flange; the second pan reinforces the first pan without abutting the inner surface.

A resin composition comprises, based on 100% by weight of the resin composition: 45-70 wt % of a main resin, 20-45 wt % of a chopped glass fiber, 1-3 wt % of a toughening resin, 0.2-0.5 wt % of an unmodified glycidyl methacrylate, and 0-10 wt % of an auxiliaries. The main resin is selected from at least one of PBT resin and PPS resin. The chopped glass fiber has a dielectric constant of 4.0 to 4.4 at 1 MHz.

A process for forming a mat containing a fiber filler including providing one or more sources of extended length fiber; feeding the one or more sources of extended length fiber simultaneously to an automated cutting machine to produce chopped tow fibers; separating the chopped fiber tow into individual chopped fibers that form a fiber filler; coating the fiber filler with a binder; depositing the fiber filler on a first sheet of thermoplastic; covering the fiber filler with a second sheet of thermoplastic to form a stack; and moving the stack to a treatment chamber to form a fiber mat.

A method for joining two objects by anchoring an insert portion provided on one of the objects in an opening provided on the other one of the objects. The anchorage is achieved by liquefaction of a thermoplastic material and interpenetration of the liquefied material and a penetrable material, the two materials being arranged on opposite surfaces of the insert portion and the wall of the opening. Before such liquefaction and interpenetration, an interference fit is established in which such opposite surfaces are pressed against each other, and, for the anchoring, mechanical vibration energy and possibly a shearing force are applied, wherein the shearing force puts a shear stress on the interference fit.

This disclosure relates generally to corrugated pipe, and more particularly to corrugated pipe with an outer wrap. In one embodiment, a pipe includes an axially extended bore defined by a corrugated outer wall having axially adjacent, outwardly-extending corrugation crests, separated by corrugation valleys. The pipe also includes an outer wrap applied to the outer wall. The outer wrap may include fibers and plastic. The outer wrap may span the corrugation crests producing a smooth outer surface.

A surface-colored glass cloth including a glass cloth which includes a warp and a weft and a plurality of colored portions which are attached to a surface of the glass cloth is disclosed. One colored portion is disposed in each area including one colored point. An average distance D between the adjacent colored points is 0.50 to 10.00 mm. When the number of warp rows is St, a warp widening degree is Et, the number of weft rows is Sy, and a weft widening degree is Ey in the glass cloth, D, St, Et, Sy, and Ey satisfy a formula: 3.3≤100×D.sup.1/2×(Et×Ey)/(St×Sy)≤25.0.

A method for forming a composite part of a gas turbine engine. The method includes assembling the composite part of a first composite material and a second composite material. The second composite material defines an outer surface of the composite part, and is selected to be curable at a cure temperature generated by heat from operation of the engine. The first composite material is selected to have an operating temperature limit less than the cure temperature. The method includes placing the composite part within the engine so that, in use, the second composite material is cured by exposure to the heat generated from operation of the engine. The second composite material thermally shields the first composite material from the heat generated from operation of the engine. The method includes operating the engine to cure the second composite material.
