A method for thermoforming a bicycle frame component includes the steps of: (A) preparing first and second casings both made of a thermoplastic material, the first casing having a first abutment surface, the second casing having a second abutment surface; (B) preparing a reinforcing unit; (C) abutting the first and second abutment surfaces against each other, and then placing the reinforcing unit at a junction of the first and second casings; and (D) thermally bonding the reinforcing unit to the first and second casings such that the first and second casings are joined to form the bicycle frame component. A bicycle frame component is also disclosed.

An aerospace vessel including a fuselage, a means for causing the fuselage to fly coupled to the fuselage, and an environmental control system within the fuselage. The environmental control system includes a duct made of closed cell thermoplastic foam, such as polyvinylidene fluoride foam.

A molded resin article and a method of manufacturing a molded resin article that suppresses generation of portions of reduced bonding strength while suppressing separation at the interface between a bond portion (secondary molding resin) on the one hand and a first body and a second body on the other. The molded resin article has a first contact surface formed perpendicular to the main surface of the first body and contacting the second body, a second contact surface formed perpendicular to the main surface of the second body and contacting the first body, and a bond portion bonding together the first body and the second body, formed by injecting molten resin into a resin channel formed by contacting the first contact surface against the second body and contacting the second contact surface against the first body and solidifying the molten resin.
