A molding made of a thermoplastic resin composition that comprises a thermoplastic resin component and an elastomer component partly blending in with each other is continuously heated at a temperature higher than 120&#xb0; C. but lower than a melting point of each of the two components for at least one hour so as thereby to cause the thermoplastic resin component to separate and precipitate in the elastomer component.

The invention provides a structure of a front part of a vehicle body that is simple and free from the risk of maloperation. In the event of a collision between the vehicle and a pedestrian, a projecting part sweeps the pedestrian by parts of his or her legs lower than the knees in the event of a collision between the vehicle and the pedestrian, causing the pedestrian to be thrown over toward the vehicle, and after an energy-absorbing member has absorbed impact energy exerted on the legs, the pedestrian is caused to drop onto the top of a hood and protected from secondary damage. In one specific example, a structure of a front part of a vehicle body in which a bumper ( ) is provided at a lower front position of a hood ( ) of the vehicle comprises a lateral supporting member ( ) provided in the front part of the vehicle body and extending in the direction of vehicle width, an energy-absorbing member ( ) provided ahead of the lateral supporting member ( ), and a projecting part ( ) provided at a lower part of the bumper in such a manner that a forward end of the projecting part ( ) juts out more frontward than the lateral supporting member ( ).

Structure of the front of a vehicle body

A polyolefin resin composition comprises a component A consisting of polypropylene or a propylene-ethylene block copolymer whose MFR is greater than 16 (g/10 minutes); a component B consisting of an ethylene based rubber; and a component D compatible with the component B. A ratio of summation of the propylene-ethylene copolymer part in the component A, the component B, and the component D to summation of the components A, B, and D is 25 wt. % or more and 45 wt. % or less. Further, a ratio of the blend quantity of the component D to summation of the blend quantities of the components B and D is less than 0.8. In this manner, the bending elastic modulus and the tensile breaking extension are included in a desired region, while the tensile breaking extension is improved.

Polyolefin resin composition

An injection molding composition includes: 100 parts by weight of a propylene-ethylene copolymer comprising a crystalline portion and a non-crystalline portion; and 17 to 33 parts by weight of inorganic particles capable of imparting at least one of rigidity and heat resistance to the propylene-ethylene copolymer. The propylene-ethylene copolymer has a melt flow rate of 15 to 50 g/10 min and a molecular weight distribution (Mw/Mn) of not less than 5. A crystalline ethylene polymer contained in the crystalline portion and a non-crystalline propylene-ethylene copolymer contained in the non-crystalline portion have a total amount ranging from 10 to 20% by weight.

A method for remanufacturing a composite resin having high tensile strength and high rigidity into a remanufactured molded product having the same tensile strength and rigidity which includes the steps of: providing a molded product of a composite resin of thermoplastic resin and liquid crystal polymer having a crystal transition point higher than a minimum moldable temperature of the thermoplastic resin; crushing the composite resin into particles or pieces; heating the particles or pieces at a temperature higher than the transition temperature of the liquid crystal polymer to obtain a molten composite resin by using an injection forming apparatus; extruding the molten composite resin at a temperature higher than the transition temperature of the liquid crystal polymer to obtain a moldable composite material of a sheet or strand form; and forming the moldable composite material into a molded product in a given shape at a temperature lower than the transition temperature of the liquid crystal polymer.

A rubber compound obtained by compounding a raw rubber, powdered vulcanized scrap rubber with its surface partially processed via a swelling treatment, a vulcanizing agent and a vulcanizing accelerator. When manufacturing the compound, the scrap rubber is treated beforhand under ordinary temperature atomosphere by being mixed with a reclaiming agent that contains petroleum process oil.

A parison is hung down between a pair of molding metallic molds in the opened state, expanding members are contacted with the specified portions of the parison, and after setting the temperature difference between the specified portions and other portions in accordance with a pre-set thickness ratio between both portions after forming thereof, the expanding members are moved while cooling the specified portions of expanding members so as to extend and thin the portions other than the specified portions of the parison, and the metallic molds are closed together so as to blow compressed air into the parison to effect blow-molding.

Blow-molding method for resinous molding product and apparatus therefor

When a resin article having at least one thickened part is blow-molded, a parison is extruded and suspended between halves of a blow mold the inner surface of which defines the outer shape of the article to be molded. An expander panel is inserted into the space inside the parison, and is moved toward the part of the inner surface of the blow mold corresponding to the thickened part of the article to press thereagainst a part of the parison. Then the blow mold is closed and pressurized gas is blown into the parison.
