Abstract
A body part for a road vehicle comprising an outer portion configured to be arranged on the outer side of a road vehicle and defining a first side of the roof panel; an inner portion configured to be arranged, with respect to the outer portion, towards a passenger compartment of the road vehicle and defining a second side of the roof panel; wherein the outer portion comprises one or more first composite material layers, each comprising a reinforcement texture; wherein the outermost layer of said one or more first composite material layers, i.e. the one visible, in use, from the outside of the road vehicle, comprises a plurality of metal filaments woven into the reinforcement texture.
Claims12
A body part for a road vehicle (1) comprising:
- an outer portion (10) configured to be disposed outwardly of a road vehicle (1) and defining a first side (11) of the body part;
- an inner portion (12) configured to be arranged, with respect to the outer portion (10), towards a passenger compartment (3) of the road vehicle (1), and defining a second side (13) of the body part;
- and
- an intermediate portion (16) disposed between the inner portion (12) and the outer portion (10);
- wherein the intermediate portion (16) comprises a layer (17) of sound-absorbing material (M) formed of a continuous closed cell foam;
- wherein the outer portion (10) comprises a plurality of first composite material layers (14), each comprising a reinforcement texture (W) formed of a carbon fiber fabric (F), wherein an outermost layer (19) of the outer portion (10), which is visible from outside of the road vehicle when in use, further comprises a plurality of metal filaments woven into the reinforcement texture (W), wherein the plurality of metal filaments (20) have a thickness equal to or greater than the carbon fiber fabric (F),
- wherein the first composite material layers (14) underlying the outermost layer (19) comprise an odd number of alternating first composite material layers of a first grammage and a second grammage, wherein the grammage indicates a weight of the respective carbon fiber fabric (F) of each first composite material layer, and
- wherein the inner portion (12), the intermediate portion (16) and the outer portion (10) are solidly coupled together forming a single multilayer body (18), and
- wherein the outermost layer (19) is resin impregnated and integrally formed as part of the multilayer body (18).
