An object is to provide an impact-absorbing structure superior in impact-absorbing capacity. An impact-absorbing structure includes a pair of flat, plate-like face plates (19) arranged to oppose each other with a predetermined distance therebetween; a core member (17) arranged between the face plates and fixed to the face plates; and a composite-material tube arranged between the face plates (7), at the core member side, the impact-absorbing member extending in one direction and fracturing progressively due to an impact compression force acting in the one direction. The composite-material tube is fixed to the face plates at one portion constituting a bonded region and is allowed to move relative to the face plates at a remaining portion constituting a non-bonded region.

The invention concerns a method for assembling at least two thermoplastic rigid parts (1, 2) which consists in superimposing the two parts (1, 2) so that they have at least one interface zone (4), at least one of the two parts bearing one or more projecting energy directing elements (5) located in the interface zone (4), exciting at least one ultrasonic source (10) contacted with one of the two parts, said ultrasonic source (10) applying a compressive force (F) to the two parts (1, 2) in a region (4.1) of the interface zone located opposite the ultrasonic source (10), moving the ultrasonic source (10) continuously at the interface zone (4) so as to form a continuous weld joint (6) by melting the thermoplastic material of the region (4.1) located opposite the ultrasonic sound (10). The invention is in particular useful for assembling laminated parts.

The invention relates to a laminate reinforcement for fibre-reinforced sunthetic resins and has for its object to provide a laminate reinforcement of highly resistant and high elasticity modulus fibres for extremely heavy-duty, yet light-weight and indent-resistent floating bodies and provides to that purpose such a reinforcement in which the laminate reinforcement is obtained by means of at least two parallel tissue tapes forming by their tissue seams a paunch gap, which is covered with a similar, but narrower covering tape, doubling of the reinforcing fibres in the area of the paunch gap in parallel relationship producing a Stringer effect, in which the warp and weft yarns of the tissue tape are made from reinforcing fibres having a higher elasticity modulus and a higher specific tensile strength than glass fibres, said fibres consisting of carbon, aramid, boron fibres or the like, the warp yarns of carbon and aramid being in intimate contact with one another and the weft yarns of aramid or carbon being spaced apart in parallel relationship by a larger distance than the warp yarns.

A joint structure for a composite member having a light-weight and low-cost structure, easy to manufacture, and resistible against a large shear load, is provided. A joint structure (1) for a composite member made from a composite material, comprising a plate for increasing thickness (40a, 40b) adhered to at least one side of the composite member (10); wherein the composite member (10) and a counterpart member (20) are fastened together by inserting and fixing a fastener member (30) into a through-hole (24, 26) formed through the composite member (10), the plate for increasing thickness (40a, 40b), and the counterpart member (20) to be joined to the composite member.
摘要:
A mechanically fastened permanent or detachable joint between two or more parts (21, 23, 25, 41), at least one of them made of a composite material, preferably carbon fibres impregnated with thermoset resin, with continuous plies from the full-composite area along the joint area (15) and including a metal reinforcement, preferably made of titanium, in the joint area (15), the joint area (15) thickness being increased in the thickness of said reinforcement plus the eventual additional composite plies laid only on the reinforced area. The metal reinforcement may consist of one or more metal foils or sheets (31) interleaved between the composite plies or one or more metal plates (33) embedded between two of the composite plies.
摘要:
A method for attaching parts. A composite male fastening component (810) is placed through at least a first part (804) and a second part (802). The composite male fastener component (810) preferably has a threaded portion. A composite female fastener component (812) is positioned adjacent to and surrounding the threaded portion of the male fastener component (810). A portion of the composite female fastener component (812) is caused to flow around and form into the threaded portion of the composite male fastener component (810). The portion of the composite female fastener component (812) that flowed around and formed into the threaded portion of the composite male fastener component (810) is re-solidified and re-consolidated such that the composite female fastener component (812) is securely attached to the composite male fastener component (810) thereby joining the mating parts.
