Improved reinforced thermoplastic hoses exhibiting improved layer adhesion, improved burst pressure response, and better fitting retention are provided. High quality adhesion between tube, cover, and reinforcement layers is exhibited. Improved methods of making reinforced thermoplastic hoses to reduce use of SVHC chemicals and improve manufacturing efficiency are also provided. The thermoplastic hoses are suitable for pneumatic and hydraulic applications.

A joined V-belt includes: a plurality of wrapped V-belt portions; and a tie band, in which outer peripheral surfaces of the wrapped V-belt portions are connected by the tie band. Each of the wrapped V-belt portions includes a belt body and a cover fabric covering an outer surface of the belt body. The belt body includes a tension member layer including a tension member, a tension rubber layer laminated on a belt outer peripheral side of the tension member layer, and a compression rubber layer laminated on a belt inner peripheral side of the tension member layer. The tie band includes a short fiber-containing rubber layer in which a short fiber is oriented in a belt width direction, and the short fiber-containing rubber layer includes a plurality of rib portions extending in a belt longitudinal direction.

The present disclosure describes a method of making a composite product (20) by additive manufacturing. The method includes providing an additive manufacturing apparatus having a build platform, the build platform having a planar face on which the product is formed; securing a fabric (22) sheet to the planar face (11) to provide a planar fabric surface thereon; additively manufacturing an intermediate object on the planar fabric surface in the apparatus (12) by light polymerizing a dual cure resin to produce an intermediate object on the build platform, the intermediate object including the fabric (22) sheet having the three-dimensional object (21) adhered thereto; and concurrently with or following the additively manufacturing step, further curing the intermediate object to produce a composite object including the fabric sheet having the three-dimensional object adhered thereto. Composite object and products are also described herein.

Expandable substrates, which are referred to as blanks, are created by compressing thermobonded nonwovens after heating the binder material above its melting temperature, and then cooling the compressed nonwovens so that the binder material hardens and holds the fibers of the nonwoven together in a compressed configuration with stored kinetic energy. A mold for the component to be manufactured can be partially filled with a number of boards (or blanks) in a stacked, vertically, adjacent or even random orientation. Upon application of heat to the boards or blanks or parts in the mold, the binder material is melted so as to allow the nonwoven material to expand in one or more directions, and thereby fill all or part of the mold. Upon cooling, the binder material again hardens, and the molded component is retrieved from the mold.
