Problems solved by technology

[0005] The vacuum resin introduction process and the resin transfer molding process require the base fabric to have a certain rigid skeleton support, and the base fabric will not be deformed by the negative pressure after vacuuming and the pressurization of the mold, thus affecting the three-dimensional effect, resulting in poor molding

Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0018] Such as figure 1 As shown, the upper warp yarn 1 and the upper weft yarn 2 are knitted to form the upper surface, the lower warp yarn 1 and the lower weft yarn 2 are knitted to form the lower surface, and the connecting yarn 3 is interspersed on the upper and lower surfaces to connect the upper and lower surfaces as a whole and form The middle layer, this is the three-dimensional hollow layer connected fabric, in which the middle layer only has the connecting yarn 3, which will be deformed under a little pressure, so the vacuum resin introduction composite process and the resin transfer molding process cannot be used, and such as figure 2 As shown, the foam strip 4 is just woven into the middle layer. The three-dimensional reinforced fabric has a certain rigid skeleton, so that the vacuum resin introduction composite process and the r...

Abstract

A three-dimensional reinforced fabric knitted with foam strips is composed of warp yarns (1), weft yarns (2), connecting yarns (3) and foam strips (4), and is characterized in that upper warp yarns (1) and upper weft yarns (2) are knitted to form an upper surface, lower warp yarns (1) and lower weft yarns (2) are knitted to form a lower surface, the upper and lower surfaces are connected with each other into a whole by connecting yarns (3), and foam strips (4) are knitted in the interlayer of the upper and lower surfaces. The foam strips (4) are knitted in the interlayer of the three-dimensional reinforced fabric to have a certain rigid support so that vacuum resin import composite process and resin transfer molding process can be adopted to improve the qualified rate, quality, accuracy and anti-fatigue and other properties of the reinforced composite material, and the foam strips are knitted to lead the fabric to have better sound and heat insulation performance.

Description

technical field [0001] The invention relates to a three-dimensional reinforced fabric woven into foam strips, in particular to a three-dimensional reinforced fabric which can adopt a vacuum resin introduction composite process and a resin transfer molding process. Background technique [0002] With the continuous deepening of the research field of three-dimensional hollow laminated fabrics, three-dimensional hollow laminated fabrics, as the base fabric of three-dimensionally reinforced composite materials, have been recognized by various industries for their advantages such as overall non-layering, light weight and high strength, and have been used in energy, storage Tanks, ships, transportation and construction industries. However, its thermal insulation performance is worse than that of the foam sandwich structure, and because the three-dimensional hollow layered fabric does not have a certain rigid skeleton support before the composite, the composite process can only use ...
