摘要:
A vehicle body structure (10) includes a floor (22) fabricated of resin, a pillar (78) fabricated of resin, and a connecting member (80). The floor (22) is disposed at a vehicle body lower side. The pillar (78) is disposed so as to extend in a vehicle body up-and-down direction at a vehicle width direction outer side of the floor (22). The connecting member (80) connects the pillar (78) with the floor (22), and is constituted of a material with higher ductility than the pillar (78) and the floor (22). Thus, a withstand load strength of a joining portion between the pillar (78) and the floor (22) is assured.
摘要:
The invention relates to a method for producing a hollow profile (10), in particular a cockpit crossmember for a motor vehicle, wherein continuous fibres (22, 32) are braided around a core (48), which reproduces the inner contour of the hollow profile to be produced, in order to create a fibrous hollow structure (46). After the braiding process, the fibrous hollow structure (46) is removed from the core (48) non-destructively and in an elastic state, formed into a final contour by means of applying internal pressure and is encapsulated with a plastic.

The invention relates to a structural component (1), notably a vehicle front end side-member, comprising a core (2) made of a first material incorporating reinforcing fibres (3), said core (2) being over-moulded with a second material (4) that gives the component its rigidity. The invention also relates to a front end of a vehicle, notably a motor vehicle, comprising such a component and to a method for the manufacture thereof.
摘要:
A chassis for a vehicle is disclosed which combines rigidity, speed of manufacture, and a small environmental footprint. Such a chassis (10) comprises a framework of interconnected tubular sections (14, 18) and at least one composite sheet (50) bonded to the framework, at least part (78) of the composite sheet comprising unidirectionally-arranged fibres, the part of the sheet and the unidirectional fibres extending obliquely rearwardly from one side of the chassis to another side. Laser cutting, CNC bending, and computer-controlled welding mean that the required production time can be kept to 120 seconds and the rigidity of the structure as a whole is sufficient. Such a chassis also has an exceptionally low carbon footprint. The sheet may comprise a plurality of sections, joined by a method allowing a positional tolerance so that any tolerance in the construction of the framework can be accommodated. The part of the sheet that is of unidirectional fibres extends obliquely rearwardly from a tubular section on one side of the chassis to another tubular section on the other side of the chassis, the fibres also being oriented obliquely rearwardly in the same sense. A further similar part (80) extends in the opposite direction, symmetrically, overlapping as necessary to form the sheet (50).

Previously existing multi-part rear wall structures comprised a multi-part rear wall installed between the rear pillars on a support structure. In the event of a side impact, therefore, not only the pillars but also the car body support structure was damaged. Accordingly, the multi-part rear wall structure (1) now comprises the vehicle pillars (3) as well as the rear wall (2) itself. This rear wall structure (1) is constructed as a separate component outside the car body support structure (4) and is only integrated in the support structure afterwards. As a result, construction and repair costs can be lowered and component weights reduced.

Provided is a structure for the front section of a vehicle body, the structure being made of at least fiber-reinforced resin and comprising as constituent elements an upper section that extends in the width direction of the vehicle in an upper part of the structure, a lower section that extends in the width direction of the vehicle in a lower part of the structure, two side sections that are connected to the upper section and the lower section on both ends thereof in the width direction of the vehicle and extend in the height direction of the vehicle body, and upper side sections that extend from both ends of the upper section in the rearward direction of the vehicle body. The upper section is configured as follows: a) a first portion, excluding the central section in the extension direction of the upper section, has a roughly U-shaped cross-section open in the rearward direction of the vehicle body; b) the first portion is configured to have an integrated structure of a metal frame with a roughly L-shaped cross-section that has a wall that follows the upper surface and the vertical surface of the roughly U-shaped cross-section and a fiber-reinforced resin frame with an approximately U-shaped cross-section that has a wall that follows the upper surface, vertical surface and lower surface of the roughly U-shaped cross-section; and c) a second portion, which is the central section in the extension direction of the upper section, has an extension section of the metal frame that has a wall that follows at least the extended surface of the upper surface and the extended surface of the vertical surface of the roughly U-shaped cross-section at the first portion, and the extension section of the metal frame constitutes an upper section formation section made solely of metal. The weight of the frame cross-section at the central section of the upper section, which collides with a pedestrian, is made lighter, making it possible to realize a structure for the front section of a vehicle body having excellent pedestrian-protecting properties that can reduce the force of impact received by a pedestrian from the structure for the front section of the vehicle body when a collision occurs.

This component comprises a first mat of felt and a second mat of felt, each felt mat comprising fibers and a resin binding the fibers. It comprises a spacer interposed between the first mat and the second mat, the first mat and the second mat being fixed to opposite faces of the spacer. At least one of the first mat and the second mat comprises at least 50 wt % of wood fibers bound together by the resin.
