Abstract

The invention relates to a fabric-reinforced assault boat and a preparation method thereof. The body of the assault boat is composed of a composite material made of unsaturated polyester resin as a matrix and the fabric for the assault boat as a reinforcing phase; the fabric for the assault boat It is a single-layer plain woven fabric formed by interweaving warp and weft yarns, and is consistent with the curved surface shape of the assault boat; all warp yarns on the single-layer plain woven fabric are parallel to the plane where any curved warp yarn is located, and all weft yarns are parallel to any curved warp yarn. The plane where the curved weft yarn is located is parallel, and the warp density and weft density are the same everywhere; the preparation method: build the model of the assault boat, make a single-layer plain weave fabric according to the model, and place the single-layer plain weave fabric on the mold Among them, unsaturated polyester resin is used as the main raw material for processing to obtain the boat body; the preparation method of a fabric-reinforced assault boat of the present invention can directly weave fabrics with curved surfaces, which improves the integrity of the fabrics and simplifies the compounding process. Forming process, the assault boat has excellent impact resistance, tensile resistance and bending resistance.

Description

technical field [0001] The invention belongs to the technical field of assault boats, and relates to a fabric-reinforced assault boat and a preparation method thereof. Background technique [0002] In war, assault boats, which are shallow draft, light, high-strength, and high-speed mobile water mobile support equipment, are frequently responsible for quickly transporting combatants and materials from water to shore, overcoming river obstacles, and conducting assaults or attacks on the other side. The task is to seize and consolidate the beachheads on the waterfront and ensure the important support equipment for the victory of the battle. In non-war operations such as flood fighting and emergency rescue, the assault boat is regarded as the "boat of life", which is used in rescuing people in distress, delivering disaster relief materials, and on water. Rescue command and other aspects play a very important role. [0003] The fabric layer reinforcement used in the assault boat...
