Provided is a resin composition which comprises 100 parts by weight of a polyamide resin comprising a structural unit derived from diamine and a structural unit derived from dicarboxylic acid, in which 70 mol % or more of the structural unit derived from diamine is derived from xylylenediamine, and in which 70 mol % or more of the structural unit derived from dicarboxylic acid is derived from a straight-chain aliphatic α,ω-dicarboxylic acid having 4 to 20 carbon atoms; 3 to 17 parts by weight of an acid-modified polyolefin having an acid modification ratio of 0.3 to 5.0% by weight; and 1 to 15 parts by weight of a compound represented by formula (1), wherein R.sup.1 represents an alkyl group having 1 to 10 carbon atoms, R.sup.2 represents an alkyl group having 2 to 12 carbon atoms, and n represents an integer of 1 to 3. ##STR00001##

This patent application claims the use of directed energy in the form of electronically scanned ion beams (e.g., proton beams) to form plastic parts by selectively curing commodity or engineering resin in the shape of the part. Polymerization is limited to the vicinity of the controlled Bragg-peak of the ion beam (i.e., where linear energy transfer is maximized), if necessary, by the use of chemical polymerization inhibitors or conditions that inhibit polymerization. This technology is more flexible than conventional or continuous three-dimension printing/production (e.g., CLIP™) because (i) it is not confined to layer-by-layer construction, (ii) it does not require a moving stage upon which the plastic part is formed, (iii) it is independent of orientation of the part (not dependent on gravity), and (iv) it allows the incorporation of fillers and pre-formed elements of almost any material into the final part. The process can be faster than “printing” processes because multiple beams can work from different directions simultaneously and the freedom from the layer-by-layer constraint allows time-saving strategies for building and final curing of the part.

A resin filler tube includes: a tubular body; a flange that protrudes radially outward from an end of the tubular body on a fuel tank side, over an entire circumference, has a plurality of layers that are of same kinds as those of the tubular body, has outer faces all of which are formed of an outermost layer material, and has a first end face, in an axial direction, forming a weld surface to be welded to an outer circumferential edge of an opening hole of the fuel tank; and a leading end tubular portion extending from a radially inner portion of the flange toward a leading end of the filler tube, and having an annular recessed groove formed at a portion of an outer circumferential surface on the flange side, over an entire circumference, for storing a melt burr generated in welding of the first end face.

Various embodiments disclosed relate to a surfacing film. The surfacing film includes a base layer. The base layer includes a thermoplastic polyurethane film comprising a reaction product of a reaction mixture of a diisocyanate, a polyester polyol having a melting temperature of at least about 30° C.; and a diol chain extender. There are many reasons to use the surfacing film including easier and more cost effective manufacturing of the surfacing film by directly extruding the base layer by mixing the reaction mixture in an extruder. Another reason to use the surfacing film is that the film has improved resistance to discoloration. Another reason to use the film is that the film shows good toughness.

A method to produce a wear resistant foil, including providing a first foil including a first thermoplastic material, applying wear resistant particles on the first foil, applying a second foil including a second thermoplastic material on the first foil, and adhering the first foil and the second foil to each other to form a wear resistant foil.

The invention relates to a multilayered pultruded structure having a weatherable cap layer over a pultruded substrate, adhered with an appropriate tie layer. The structure provides improved weatherability and surface quality for pultruded structures. The invention is especially useful to provide a weatherable pultruded polyurethane, with an acrylic or styrenic cap layer. The weatherable polyurethane (PU) pultrusion of the invention provides an increased modulus over polyester pultrusions, making the weatherable PU pultrusion useful in commercial applications, and applications requiring a higher transverse modulus.
