Abstract: A composite panel includes a first skin, a second skin, a core arranged between the first skin and the second skin, reinforcing pins connected by a first end to the first skin and connected by a second end to the second skin, in which inclined reinforcing pins form an angle of from 25 degrees to 40 degrees with the first skin and/or the second skin.

Abstract: A stabilization device includes a molding tool onto which at least one fiber layer having a binder material is placed. The device also includes a consolidation device having sonotrode that applies ultrasonic energy to the fiber layer. The molding tool positions the fiber layer in a predetermined position relative to the sonotrode.

Abstract: A multi-purpose carrying bag or case having a parallelepiped shape is provided. The carrying bag or case comprises a shell of a watertight and airtight, rip-resistant material, the shell having top and bottom portions, first and second longitudinal side portions and first and second end portions; a slot-type opening provided in said upper portion and being closeable by means of a watertight and airtight zipper; and a fill-valve provided in said shell for filling the interior of the carrying bag or case.

Abstract: An inflatable boat includes a buoyant body having a pair of elongated lateral portions which are arcuately raised at both the bow region and the stern region thereof, a stern bulkhead connected to the lateral portions and extending between them, and a bottom which is water-tightly connected to the lateral portions and to the stern bulkhead and defines a compartment therewith. The lateral portions are constituted by inflatable tubular elements which are interconnected at the bow region of the inflatable boat by a rigid connecting element. The stern regions of the tubular elements extend beyond the stern bulkhead and arcuately converge toward one another in the rearward direction, being spaced from one another by a distance which at least corresponds to the maximum diameter of the tubular elements. A support element is mounted on the stern regions, and a rudder is mounted on the support element with freedom of movement relative thereto.

Abstract: A deck portion of an inflatable boat has, when inflated, a plurality of alternating external bulges and grooves extending substantially longitudinally of the boat and diverging at the front part of the deck portion in the rearward direction of the boat so as to be spaced the greatest transverse distance at an access opening in which a user of the boat sits to thereby laterally divert water splashing on the deck during travel of the boat. A rigid seat shell is received in the opening and supported in the deck and hull portions of the boat. A collar surrounds the access opening and has a sealing portion which sealingly contacts a portion of the seat shell to prevent seepage of water between the collar and the seat shell. The seat shell may be used as a container for accommodating the deflated and folded boat. The seat may be equipped with a carrying belt so that it can be transported on the back of the user.
