Abstract
The invention relates to a motor vehicle door member (10) comprising an appearance part constituted by an outside skin (12) of polyolefin, and a structural part (14) having a coefficient of expansion that is less than that of the skin, the two parts being united by a bead of adhesive placed on a face of one of the two parts facing a face of the other part. The adhesive presents: breaking elongation lying in the range 20% to 800%; purely elastic elongation over a fraction of its breaking elongation; and Young's modulus lying in the range 0.5 MPa to 300 MPa. After bonding, the bead of adhesive presents a nominal thickness lying in the range 0.8 mm to 3 mm.

A motor vehicle door member (10) comprising an appearance part constituted by an outside skin (12) of polyolefin, and a structural part (14) having a coefficient of expansion that is less than that of the skin, the two parts being united by a bead of adhesive placed on a face of one of the two parts facing a face of the other part, the door member being characterized in that the adhesive presents:
- breaking elongation lying in the range 20% to 800%;
- purely elastic elongation over a fraction of its breaking elongation;
- and
- Young's modulus lying in the range 0.5 MPa to 300 MPa,
- and in that the bead of adhesive, after bonding, presents a nominal thickness lying in the range 0.8 mm to 3 mm.
