The hydroformed composite material includes a formed film layer that includes a plurality of extended cells containing continuous fibers and/or fibrils of the expanded spun bonded nonwoven layer.

Composite gypsum panels and methods of making thereof are provided. The composite gypsum panels can include one or more gypsum panel substrates having one or more urethane layers applied thereto. The urethane layers can be or can include foamed urethane layers, provided for structural integrity while being lighter than conventional gypsum panels having the same overall thickness. The panel can have a dense coating layer, a foamed coating layer, or both a dense coating layer and a foamed coating layer. The dense coating layers and foamed coating layers can each offer certain advantages over conventional gypsum panels. Additionally, in various aspects, the composite panel includes a water-resistant barrier and increased nail and screw retention.

A laminate of the present invention includes a first member which contains a thermoplastic polymer and through which laser light is transmitted and a second member which contains a thermoplastic polymer and absorbs laser light, wherein the first member is directly bonded to the second member, and A represented by the formula 1: A=−9×D+Wa−45 is more than zero. D represents a distance between a Hansen solubility parameter of the thermoplastic polymer of the first member and a Hansen solubility parameter of the thermoplastic polymer of the second member, and Wa represents work of adhesion calculated from each surface free energy of the first member and the second member. Such a first member and a second member are firmly bonded to each other without using a bonding sheet.

The present invention relates to a composite article comprising at least two layers (A) of component a) and at least one layer (B1) of component b). The respective layers (A) and (B1) are alternately linked together. The component a) has a compressive modulus of at least 10 MPa and can, therefore, be considered as a comparably rigid component, which can be also assigned as rigid core element, in contrast thereto the component b) has a compression stress value at a compression of 40% of not more than 20 kPa. By consequence, component b) can be considered as a comparably flexible (elastic) component. Therefore, the composite articles according to the present invention can be considered as semi-flexible materials due to the combination of alternating rigid and flexible segments (layers) within those composite articles. The composite articles according to the present invention may further comprise at least one layer (B2) of component b), which layer is also alternately linked together with the respective layers (A). In addition, at least one layer (B2) crosses at least one layer (B1) with an angle α in the range of 0°<α<180°, wherein both layers (B1) and (B2) are made of component b). The present invention further relates to a method for producing those composite articles as well as to the use of those composite articles in composite applications, for example, wind rotor blades or boat hulls or insulation applications, for example for curved walls or roofs or between rafters.
