Abstract
The present invention relates to a hybrid frame rail including a pair of metallic flanges separated by a composite web including a first and second sections, each section including a pair of elongated bands separated by a transversely extending wall which includes a plurality of protrusions integrally connected to complimentary protrusions provided on the complimentary web section. To manufacture the hybrid frame rail, the metallic flanges are attached over the elongated bands of the web such that the web is entrapped between the metallic flanges.
Claims25
A hybrid frame rail, comprising:
- a composite web including first and second sections, each section including a pair of elongated bands separated by a transversely extending wall, said walls having inwardly extending protrusions which are positioned adjacent to complimentary protrusions provided on the opposing web section;
- and
- a pair of metallic flanges wherein said metallic flanges are attached substantially contiguously over the elongated bands.
A hybrid frame rail, comprising:
- a composite web including first and second integrally connected sections, each section including first and second elongated bands separated by an integral transversely extending wall having a plurality of spaced apart inwardly extending protrusions extending therefrom;
- and
- a pair of metallic flanges which are attached to said web such that a first flange is disposed contiguously over the first elongated band and the second flange is disposed contiguously over the second elongated band thereby sandwiching the composite web between the metallic flanges.
A hybrid frame rail, comprising:
- a composite web including first and second elongated bands separated by a substantial transversely extending wall;
- and
- a pair of metallic flanges which are attached to said web such that a first flange is disposed contiguously over the first elongated band and the second flange is disposed contiguously over the second elongated band thereby sandwiching the composite web between the metallic flanges.
A chassis for a vehicle, said chassis comprising:
- a pair of frame rails and at least one cross member, at least one of the frame rails including:
- a composite web including first and second elongated bands separated by substantially transversely extending wall, a first metallic flange attached to the first elongated band, and a second metallic flange attached to the second elongated band.
