Disclosed herein are a fiber-reinforced material and an article made of the same. The fiber-reinforced material includes a fiber assembly and a matrix material coating the fiber assembly, the matrix material is a thermoplastic resin composition obtained by blending a polyolefin resin, a polyamide resin, and a modified elastomer that reacts with the polyamide resin. When a puncture test is performed at a striker speed of 1-4 msec and when a maximum impact force is applied is defined as Pand a deflection at break is defined as P, P/P≥4. When the amount of energy absorbed before a maximum impact force is applied is E, the amount of energy absorbed after a maximum impact force is applied and before break is E, and a total amount of absorbed energy of Eand Eis E, the ratio of E:Eis 70% or more.

Fiber-reinforced material and structure

A thermoplastic resin composition, a molded body, and first and second production methods are disclosed. The thermoplastic resin composition contains a polyolefin resin, a polyamide resin, and a modified elastomer and shows non-Newtonian properties in a fluidized state. The molded body includes the thermoplastic resin composition. The first production method includes molding the thermoplastic resin composition at a shear rate of 80 secor more and a standby step in which resin composition is on standby at a shear rate of 0 secor more but less than 80 sec. The second production method includes molding the resin composition at a shear rate Xto obtain part of a molded body and molding the resin composition at a shear rate Xto obtain another part of the molded body, wherein an absolute value of a difference between Xand Xis 200 secor more.

Thermoplastic resin composition, molded object, and production methods therefor

Disclosed herein are a vehicle door trim board that is less likely to break due to partial use of an impact resistant resin and a door trim using such a vehicle door trim board. A vehicle door trim board includes a reinforcing part made of an impact resistant resin containing a polyolefin resin, a polyamide resin, and a compatibilizer, wherein the compatibilizer is a modified elastomer having a reactive group that reacts with the polyamide resin. The door trim includes: the vehicle door trim board; and a surface skin layer provided on a design surface side of the vehicle door trim board.

Trim board for vehicle door, and door trim

Disclosed herein are a thermoplastic resin sheet having excellent mechanical strength and excellent conformability during molding, a laminated sheet using such a thermoplastic resin sheet, and a molded body. The thermoplastic resin sheet includes a thermoplastic resin containing a polyolefin resin, a polyamide resin, and a compatibilizer, wherein the compatibilizer is a modified elastomer having a reactive group that reacts with the polyamide resin. The laminated sheet includes a base layer containing a polyolefin resin and the thermoplastic resin sheet bonded to one surface of the base layer. The molded body includes a base body containing a polyolefin resin and the thermoplastic resin sheet or the laminated sheet bonded to one surface of the base body.
