ABSTRACT:
When attaching components to composite members, for example leaf springs of composite fibre reinforced resin material, it is necessary to avoid stress concentrations and also the access of foreign matter between the spring and the component since this can cause abrasion and break down of the spring. A composite leaf spring having upper and lower planar surfaces has a two element component clamped to it as indicated by the arrows. Liners of elastomeric material are interposed between one element and the upper planar surface and between the other element and the lower planar surface. Towards their ends the surfaces of the elements adjacent the spring diverge from the spring and the liners are shaped to fill the divergencies. The liners extend beyond the ends of the elements to form sealing lips at the spring surfaces. In an eye end attachment at an end of a composite spring in a one piece component may be used.
