A fiber reinforced metal composite having a metal layer and a fiber layer which are arranged in a stack, and adjacent layers are fixed by bonding; the composite has a two-layered or three-layered structure, wherein one layer is closely adhered to another layer and the thickness of the layer is from 0.6 mm˜0.9 mm. Such structure changes the structure of the existing fiber metal composite characterized by generally having more than three layers, and greatly reduces the thickness of the composite while maintaining good mechanical properties. Also disclosed is an application of fiber reinforced metal composite in the field of luggage case manufacturing, providing two preparation methods for providing fiber reinforced metal case shell with simple and available operations.

Thermally insulated carrier bag to be carried by one person, comprising an insulation cover with a base insulation element, a peripheral insulation side wall (and a cover insulation element, which are designed in such a way as to form a receiving space. Enclosing, further comprising a carrying case with a base element, a peripheral side wall and a cover element, which are designed in such a way as to enclose an interior space for the insulation case, the base insulation element and/or the insulating side wall and/or the lid insulating element comprise at least one vacuum insulating element, and the carrying case has at least one carrying element for carrying by one person.

A transportable device for heating foodstuffs includes a container for receiving the foodstuff as well as a closed-off heating chamber which adjoins the container and is thermally coupled thereto while simultaneously being hermetically separated therefrom via a shared, thermally-conductive wall. The heating chamber includes a first chamber and a second chamber that are separated by a water vapor-permeable wall. In the first chamber is a substance or a substance mixture which, when a liquid, preferably water, is supplied, generates heat in an exothermic chemical reaction with water vapor being formed. In the second chamber, a zeolite is located which can adsorb the water entering from the first chamber via said water vapor-permeable wall, generating heat. A transportable heating element which can be used in the device contains a hermetically-sealed heating chamber that adjoins a thermally-dissipating outer wall.
