An example molding method includes: feeding a molten foamable resin by injection in a cavity formed in a molding die; allowing the molten foamable resin to flow in the cavity; and foaming and solidifying the molten foamable resin to mold a resin foam product. The example molding method performs flow rate control by controlling a flow rate of the molten foamable resin at a welding portion to be equal to or higher than a flow rate of the molten foamable resin at an upstream portion adjacent to the welding portion.

Method and apparatus for molding resin foam product

The resin-made floor panel structure including a trunk floor Fmade of resin integrally forming a spare tire storage space S, and a trunk board Bmade of resin disposed so as to cover the floor panel, fitting parts Sw, Bkfor achieving the closure of the spare tire storage space are integrally formed respectively in the trunk floor and trunk board. Thereby, in using resin materials for a floor panel, transmission of noise in the floor section to the compartment side can be suppressed by a relatively simple structure without increasing the weight.

Resin-made floor panel structure

The resin-made floor panel structure including a trunk floor F made of resin, and a trunk board B made of resin disposed so as to cover the trunk floor, a foamed layer having foams exposed at least in part is provided only on the side of the trunk board facing the floor panel. Thereby, in using resin materials for a floor panel, transmission of noise in the floor to the compartment side can be suppressed by a relatively simple structure without increasing the weight.

A laminate comprising a pair of thermoplastic resin members having fluctuation of clearance between the adhesion surfaces thereof, and a thermoplastic material foam layer which adheres the pair of the thermoplastic resin members. This laminate is formed from thermoplastic resin as a whole and can absorb the fluctuation of clearance between the members, and the thermoplastic resin members are firmly adhered with the thermoplastic material foam layer.

The present invention relates to a method for preparing a composite material comprising a matrix resin of a thermal plastic resin and a liquid crystal resin which has a liquid crystal transition temperature higher than the minimum temperature of capable of molding said thermal plastic resin and which is formed into a fiber structure as a reinforcing material. The method is characterized in that the composite composition is subjected to a melt extrusion process at an apparent shear rate of 3.times.10.sup.2 to 10.sup.5 sec.sup.-1 and above the liquid crystal transition temperature. The resulting material in a filament or thin film has fibers of the liquid crystal resin having an aspect of more than 3 in the matrix resin, so that it is provided with an improved tensile strength by further being subjected to a drawing process at a drawing ratio of 11 to 120. As the composite materials have too small diameter or thickness to be molded in a desired product, they are preferably further subjected to a gathering process, a folding process or a laminating process in which a plurality of strand or film materials are welded to each other at the surface thereof and formed into a strand or sheet form capable of molding.

A polyurea resin composition for RIM or coating use Comprises (a) a polyoxyalkylenepolyamine, (b) an aromatic polyamine and/or a xylylenediamine and (c) a polyisocyanate compound with either one or both of components (a) and (b) having been modified by a Michael reaction with a vinyl monomer having an electron attracting group to convert the primary amino group thereof to a secondary amino group. The composition also contains as an internal mold release a polyoxyalkylene glycol mono-C.sub.4 -C.sub.1, alkyl ether and/or as a polyamine component a reaction product between a primary aromatic polyamine and a polyglycidyl ether.
