A carbon/carbon part and processes for making carbon/carbon parts are provided. The process involves forming steps, carbonization steps and densification steps. The forming steps may include needling fibrous layers to form fibers that extend in three directions. Pressure may be applied to a fibrous preform at an elevated temperature to increase the fiber volume ratio of the fibrous preform. The densification steps may include filling the voids or pores of the fibrous preform with a carbon matrix.

A sheetlike composite material including at least one layer A of a nonwoven thermoplastic fiber web or a thermoplastic film, and at least two unidirectional oriented-fiber layers B and B, the layers B and B having a bidirectional fiber orientation. The layers are not only needled but also stitched to one another.

A coated nonwoven product used to make engine hood insulation material is produced by a method which involves needle punching a carded, cross-lapped web, then calendering the resulting web and then applying a foam coating. Rotary screen printing is used to apply a dot pattern of an acrylic emulsion to the dried, foam-coated web. Thermoplastic and/or thermoset material is deposited onto the acrylic coating and excess material is removed by vacuum, leaving a corresponding dot coating pattern of said material. The coated web is heated using infrared energy before cooling, cold calendering and winding-up.
