A method and process is provided for manufacturing a glassed reinforced polymer composite laminate panel. The method and process includes the steps of providing a mold including a flexible polymer film; depositing a layer of gel coat on the flexible polymer film; curing the layer of gel coat to provide a semi-rigid intermediate panel; applying a layer of resin material overtop of the cured gel coat layer; laying a sheet of woven or non-woven surface veil material over top of the cured gel coat layer; laying a sheet of glass reinforced matte overtop of the surface film sheet; applying a second layer of resin material overtop the sheet of glass reinforced matte to form the glassed reinforced polymer composite laminate panel; and curing the glassed reinforced polymer composite laminate panel. The method for manufacturing the composite laminate panel can be a continuous process making a panel of indeterminate length.

A fiber-reinforced plastic molded body includes: a laminated body having a configuration of laminating a sandwich structure member obtained by laminating one layer or two or more layers of a unidirectional fiber-reinforced resin constituted from a unidirectional continuous fiber and a matrix resin on both surfaces of a core layer and one layer or two or more layers of a woven fiber-reinforced resin constituted from a woven fiber and a matrix resin such that the one layer or two or more layers of a woven fiber-reinforced resin are disposed on the design surface side of the unidirectional fiber-reinforced resin; and the resin member is not substantially exposed in a projection plane from the woven fiber-reinforced resin side.

A fiber-reinforced resin sheet includes a resin film which is thermoplastic, and a plurality of reinforcing fibers that are placed on the opposite surfaces of the resin film in a state of being oriented in the same direction after being opened from a bundle of reinforcing fibers. The resin film has a thickness of 5 μm or more and 15 μm or less, an areal weight of the reinforcing fibers is 25 g/m.sup.2 or more and 60 g/m.sup.2 or less, and a volume content of the reinforcing fibers is 60% or more and 75% or less. The fiber-reinforced resin sheet has a thickness of 30 μm or more and 65 μm or less.

A gasket is disclosed for use as an environmental seal between a first aircraft part having planer surface and a second aircraft part having a planer surface, the two planer parts spread apart and engaged with fasteners. The gasket, in some embodiments, is compressible between the planer surfaces. The gasket, in some embodiments, comprises a first tabular portion having tabular portion properties and having a first tabular thickness and a length and a width, the length and width much greater than the first tabular thickness; and a second tabular portion having tabular portion properties having a second tabular thickness, a length and width, the length and width much greater than the second tabular thickness; and a tabular skeleton. The first and second tabular portions and the skeleton are positioned parallel to one another. The skeleton is at least partly contacting one of the tabular portions. The first tabular portion and the second tabular portion differ in at least one tabular portion property.

The invention relates to a three dimensional shaped article having an outer and inner surface, the outer surface comprising at least one fabric (100) of polyethylene fibers having a tensile strength of at least 1.5 GPa, the fabric is impregnated with an acrylic based thermoplastic material. The three dimensional shaped article may further comprise monolayers with unidirectional aligned fibers. The three dimensionally shaped article has an improved surface appearance which would therefore need little or no post treatment and has good adhesion to coatings and paints.

Disclosed is a friction-reducing and anti-wear composite material for a wading kinematic pair and a method of preparing the same. The friction-reducing and anti-wear composite material is prepared from carbon fiber (CF) among inorganic fillers, polyimide (PI) and polyether ether ketone (PEEK). These three materials are wet-mixed, dried and placed in a mold followed by curing by a heat press. The cured product is cooled and demolded to obtain the CF/PI/PEEK friction-reducing and anti-wear composite material for a wading kinematic pair. Tribological properties of the PEEK material are enhanced due to synergistic effect arising from hybrid organic-inorganic filling. The friction-reducing and anti-wear composite material provided in the invention has significantly reduced friction coefficient and wear volume loss under the seawater environment.

A process of preparing carbon fiber reinforced polymer (CFRP) intermediate products is described wherein the carbon fibers are prepared from a carbon fiber precursor and then in-line impregnated with a polymeric resin as part of a continuous process. The process can provide cost savings compared to processes wherein carbon fibers are prepared and then impregnated with polymeric resins in a separate process, thereby making the use of CFRP materials more economically feasible. Also described is a system for preparing carbon fiber from a carbon fiber precursor and impregnating the carbon fiber with polymeric resin to provide CFRP intermediate products, such as continuous tapes or rods or discontinuous flakes or pellets.
