The invention discloses a bamboo winding composite material product with a sandwich structure, which sequentially includes an inner reinforcement layer, a sandwich layer and an outer reinforcement layer from the inside to the outside, and the inner reinforcement layer and the outer reinforcement layer are made of a One or more layers of resin bamboo strips are wound to form a bamboo strip layer. The sandwich layer is composed of one or more sets of alternating layers of bamboo slices in the circumferential direction and bamboo slices in the axial direction. The bamboo slice layers in the circumferential direction It is composed of a plurality of spaced circumferential bamboo segments distributed axially along the sandwich structure bamboo winding composite material product, and the circumferential bamboo segments are one or more layers of bamboo sheets adhered with resin. Formed, the axial bamboo sheet layer is formed by the axial bamboo sheet curtain formed by arranging multiple rows of bamboo sheets arranged in parallel in the axial direction adhered with resin, and wrapping one or more layers in the ring direction on the bamboo sheet layer . At the same time, it discloses a manufacturing method for manufacturing the above-mentioned sandwich structure bamboo winding composite material product. The invention can meet the required strength and rigidity of the product, and at the same time, has good overall forming effect, small thickness, short winding cycle and high efficiency, and is suitable for the manufacture of bamboo winding composite material products with large cross-sectional area. In addition, the sound absorption and noise reduction function is also improved.
