AI Technical Summary

Problems solved by technology

If the gap is too small (0 to 4mm), the electrophoretic coating will not be able to effectively protect the product from erosion because there is not enough space for the coating to flow

Embodiment Construction

[0017] The reinforcement includes a carrier having a plurality of outer walls spaced apart from one another. The carrier defines a channel extending generally parallel to the longitudinal axis defined by the chamber. A layer of material is disposed on at least one outer wall within the channel such that the electrocoat can flow through the channel before the layer of material expands and the channel is substantially filled after the layer of material expands. In one embodiment, the new flow channels for the electrocoating process are created by removing the transverse ribs from the carrier, the layer of material interconnecting the longitudinal ribs after expansion in the baking process. In another embodiment, the carrier may include transverse ribs that provide additional support to the carrier without interfering with the electrophoretic coating process.

Abstract

A reinforced member comprises a carrier having a plurality of outer walls spaced from one another.The carrier defines a channel extending substantially parallel to the cavity defined by the longitudinal axis.At least one wall of the outer layer of material disposed within the channel, such that the material layer expands prior to electrocoating material can flow through the passage, and after the material layer expands, the channel is substantially filled.

Description

technical field [0001] Stiffeners are used in various industries to provide structural support or reduce noise and / or vibration in various products. For example, in the automotive industry, reinforcements may be used to strengthen beams, pillars, rails, nodes, doors or roofs of vehicles. The reinforcement may comprise a carrier disposed in a cavity of the product on which a layer of material such as structural or acoustic foam or adhesive is disposed. The carrier can be made of plastic or metal bonded to the layers of material. Therefore, the layer of material is usually sticky. Background technique [0002] In patent document FR 2 749 263 a reinforcement is disclosed in which the foam material in the unfoamed state fills almost the entire space between the longitudinal ribs and the structure. This requires that the foam be designed to fill the entire cavity. The function of the foam material between the longitudinal ribs is to connect the carrier to the structure to be ...
