The present invention relates to a molding made of reactive foam, wherein at least one fiber (F) is arranged partially inside the molding, i.e. is surrounded by the reactive foam. The two ends of the respective fiber (F) not surrounded by the reactive foam thus each project from one side of the corresponding molding. The reactive foam is produced by a mold foaming process. The present invention further provides a panel comprising at least one such molding and at least one further layer (S1). The present invention further provides processes for producing the moldings according to the invention from reactive foam/the panels according to the invention and also provides for the use thereof as a rotor blade in wind turbines for example.

A tubular structure for transporting heat transfer fluid including at least: i) a layer (1) in contact with the fluid including at least one thermoplastic polymer P1 that is semicrystalline with Tm1 greater than or equal to 160° C., as determined according to the standard 1 1357-3 (2013) or amorphous with Tg1 greater than or equal to 100° C., as determined according to the standard 1 1357-2 (2013), said layer (1) containing no fibers, ii) a layer (2) including at least: (a) a thermoplastic polymer P2 that is semicrystalline, in particular a polyamide with Tm2 greater than or equal to 170° C. or amorphous with Tg2 greater than or equal to 100° C., or a polyolefin with Tm greater than 100° C.; (b) optional continuous fibers, the polymer P2 being identical to P1 or different from P1 in which case the polymers P1 and P2 adhere at least partially to one another.

Disclosed herein is an intrinsically self-healing composite based upon in situ thermal remendability of an embedded polymeric interphase. The fiber-reinforced composite (FRC) material may incorporate a thermoset polymer with a defined glass transition temperature (T.sub.g) and/or a thermoplastic material of amorphous or semi-crystalline nature. The polymeric interphase can be incorporated as a plurality of particles, fibers, meshes, films, or 3D-printed structures. The self-healing composite includes a resistive heating component as a structural element that minimizes electrical energy demand and impact on mechanical integrity. Healing occurs in situ via resistive heating and can be enabled below, at, or above the glass-transition temperature of the FRC matrix, demonstrating viability for in-service repair under sustained loads. In addition to providing rapid healing functionality, the polymeric interphase increases inherent resistance to interlaminar fracture. Repeated heal cycles have been achieved in a double cantilever beam (DCB) fracture test without significant degradation in performance.

A thermoplastic composite article comprising a porous core layer and an open cell skin disposed on a first surface of the core layer is described. The composite article comprises a noise reduction coefficient of at least 0.5 as tested by ASTM C423-17 and a flame spread index of less than 25 and a smoke development index of less than 150 as tested by ASTM E84 dated 2009.

Described herein are fire hoses incorporating new combinations of materials to increase the hose's resilience. Resilient hoses include those made with silicone-coated fabrics or with thermally-resistant fabrics or both.

A piston for a heavy duty diesel engine including a composite layer forming at least a portion of a combustion surface is provided. The composite layer has a thickness greater than 500 microns and includes a mixture of components typically used to form brake pads, such as a thermoset resin, an insulating component, strengthening fibers, and an impact toughening additive. According to one example, the thermoset resin is a phenolic resin, the insulating component is a ceramic, the strengthening fibers are graphite, and the impact toughening additive is an aramid pulp of fibrillated chopped synthetic fibers. The composite layer also has a thermal conductivity of 0.8 to 5 W/m.Math.K. The body portion of the piston can include an undercut scroll thread to improve mechanical locking of the composite layer. The piston can also include a ceramic insert between the body portion and the composite layer.

Golf balls having covers made of thermoplastic polyurethane compositions are provided. Multi-piece golf balls can be made. Polyurethane primer coatings and polyurethane top-coatings are applied to the thermoplastic polyurethane cover. Different coating methods can be used. Isocyanate-rich and polyol-rich polyurethane coatings can be applied. In one embodiment, the golf ball can be treated with a multi-functional isocyanate prior to applying the coatings. The polyurethane cover composition and surface coatings can further include catalysts, ultraviolet (UV)—light stabilizers, and other additives. Heat is used to cure the coatings. The coating methods have many benefits and the finished balls have good physical properties.
