Problems solved by technology
Due to the poor mechanical properties of wood and foam plastic core materials, they are generally rarely used in the production field, especially for large-scale FRP products or important FRP products that have high requirements for them, such as FRP speedboats and military products (cannonballs). It is not ideal to use steel as the core material of reinforcing ribs for glass fiber reinforced plastic packaging boxes, etc.
This is because the expansion coefficient of steel is much greater than that of FRP, which will directly cause the reinforcement marks on the surface of FRP products and the peeling of the steel core material, which will directly affect the quality of FRP products, and will also cause FRP products to be too bulky , which brings difficulties to its movement (mechanical products) and handling (packaging boxes)
Does not meet the requirements of lightweight FRP products

Embodiment Construction
[0020] The present invention will be further described below through the description of specific embodiments with reference to the accompanying drawings.
[0021] A typical specific implementation, as attached figure 1 , 2 , 3 shown.
[0022] A reinforcing rib for FRP products, including a FRP product main body 1, and a non-metallic material warp and weft woven with a first fabric layer 2-1 and a second fabric layer 2-2, which are supported by a standing core The three-dimensional core material woven fabric 2 formed by 2-3 connections, and it:
[0023] The three-dimensional core material woven fabric 2 is an I-shaped structure, and the width of its first fabric layer 2-1 is close to the width of the second fabric layer 2-2 and 2 multiplied by the height of the standing core column 2-3. and;
[0024] The second fabric layer 2-2 of the three-dimensional core material woven fabric 2 is closely attached to the surface of the main body 1 of the FRP product, and the first fabric...

The invention discloses a reinforcing rib for a glass fiber reinforced plastic product. The reinforcing rib for the glass fiber reinforced plastic product comprises a glass fiber reinforced plastic finished product main body and a three-dimensional core material woven fabric. The reinforcing rib for the glass fiber reinforced plastic product is mainly characterized in that the three-dimensional core material woven fabric is taken as a reinforcing rib core material, the core material is spliced with the glass fiber reinforced plastic finished product main body into a whole by virtue of resin. The reinforcing rib for the glass fiber reinforced plastic product has the advantages that structure is reasonable, a technology is simple, integrality between the core material and the glass fiber reinforced plastic finished product main body is good, weight is smaller compared with that of the prior art and bending and deformation resisting capability is strong and overcomes the defects caused by the fact that a hard core material is adopted for manufacturing the reinforcing rib in the prior art.
Description
technical field [0001] The invention relates to a reinforcing rib of a glass-steel product, and belongs to the technical field of glass-steel product manufacturing. Background technique [0002] The reinforcing ribs of traditional FRP products are mainly made of steel, wood and foam plastics (mostly steel) as the core material of the reinforcing ribs. Due to the poor mechanical properties of wood and foam plastic core materials, they are generally rarely used in the production field, especially for large-scale FRP products or important FRP products that have high requirements for them, such as FRP speedboats and military products (cannonballs). It is not ideal to use steel as the core material of the reinforcing rib for glass fiber reinforced plastic packing boxes and the like. This is because the expansion coefficient of steel is much greater than that of FRP, which will directly cause the reinforcement marks on the surface of FRP products and the peeling of the steel core...
