Problems solved by technology
The material composition is single, the structure is simple, the overall strength is poor and the rigidity is insufficient, so it is only suitable for filling materials
It is difficult for a single solid material to fully meet people's increasing requirements in terms of weight, density, cost, strength, rigidity, surface touch, etc.

Embodiment Construction
[0011] The implementation of the present invention will be illustrated by specific specific examples below, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.
[0012] A lightweight composite board, comprising a high-density upper skin layer 1, a high-density lower skin layer 2, and a low-density interlayer 3 between the high-density upper skin layer 1 and the high-density lower skin layer 2, and a high-density upper skin layer 1 1. The high-density lower skin layer 2 and the low-density interlayer 3 form a sandwich sandwich structure, the high-density upper skin layer 1 and the high-density lower skin layer 2 are made of multi-density polyurethane material, and the low-density interlayer 3 is made of low-density polyurethane and Made of fiberglass blend.
[0013] A further improvement of the present invention lies in that the low-density interlayer 3 is provided with a rei...

The invention discloses a lightweight composite plate. The lightweight composite plate comprises a high-density upper surface layer, a high-density lower surface layer and a low-density sandwich layerbetween the high-density upper surface layer and the high-density lower surface layer; the high-density upper surface layer, the high-density lower surface layer and the low-density sandwich layer form a sandwich structure; the high-density upper surface layer and the high-density lower surface layer are made of a multi-density polyurethane material; the low-density sandwich layer is prepared bymixing low-density polyurethane and glass fibres; a strengthening keel is arranged in the low-density sandwich layer; the strengthening keel is made of a glass fibre-reinforced plastic grid or a cellular material; and the glass fibres are long fibre reinforced glass fibres. The lightweight composite plate has the advantages of simple structure, high overall strength and wide application range.
Description
technical field [0001] The invention relates to the field of composite materials, in particular to a lightweight composite board. Background technique [0002] Existing lightweight foam materials such as polyurethane insulation board, EPS foam insulation board and so on. The material composition is single, the structure is simple, the overall strength is poor and the rigidity is insufficient, so it is only suitable for filling materials. It is difficult for a single solid material to fully meet people's increasing requirements in terms of weight, density, cost, strength, rigidity, surface touch and other properties. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to solve the deficiencies in the prior art, and provide a concept based on the strengthening performance of composite materials, using a variety of different materials to combine, and the strength-to-weight ratio and rigidity-to-weight ratio of the board tend to be opt...
