In some examples, a method includes depositing a mixture including a resin and an additive powder via a print head of a three-dimensional printing system to form a carbon fiber preform including a plurality of individual carbon fiber layers, wherein each individual layer of the plurality of individual carbon fiber layers includes a plurality of carbon fibers and the mixture of the resin and the additive powder.

A bearing laminate can include a metal support layer, a foam layer overlying the metal support layer, the foam layer including a polymeric foam; and a sliding layer overlying the polymeric foam layer, the sliding layer comprising a polymer matrix. Bearing articles made from the bearing laminate can have exceptional damping properties, such as a high damping ratio combined with a low dynamic stiffness.

A method of fabricating a composite component is provided. The method includes forming a fibrous preform, performing a first densification on the fibrous preform to generate a densified fibrous preform, heat treating the densified fibrous preform to form a heat treated densified fibrous preform, performing a second densification on the heat treated densified fibrous preform, and performing a silicon melt infiltration after densifying the heat treated densified fibrous preform to form the composite component.

A high-friction road patch may comprise an aggregate capable of providing sufficient friction between a road surface and vehicle wheel. In some embodiments, the patch may comprise a waterproof, asphalt overlay with a first layer of cured bitumen and calcined bauxite aggregate particles, a second layer of viscous bitumen and a reinforcement component, and a binder layer for bonding the overlay with the road surface. The resulting product may provide a sufficient skid resistance value in an overlay that is far less susceptible to or incapable of debonding as with prior art solutions.

An apparatus includes a top pad comprising a plurality of protrusions and a plurality of grooves between the plurality of protrusions, a first adhesive film underlying the top pad, and a first anti-deformation layer underlying and attached to the top pad through the first adhesive film. The first anti-deformation layer has a first hardness. The apparatus further includes a second adhesive film underlying the first anti-deformation layer, and a main support layer underlying and attached to the top pad through the second adhesive film. The main support layer has a second hardness lower than the first hardness.

The application relates to a brake pad for a disk brake system and to a disk brake system. The proposed brake pad comprises a back plate having a front side for facing a brake disk of the disk brake system and a friction layer arranged on the front side of the back plate for contacting a friction surface of the brake disk. The brake pad further comprises an underlayer arranged between the front side of the back plate and the friction layer. The back plate comprises a recess. The underlayer extends into the recess of the back plate.
