Abstract

The utility model discloses a fiberglass woven fabric of reinforced substrate of fiber glass reinforced plastics piece, which has a relatively high requirement for the translucency and is further named woven transparent fiberglass woven fabric which is composed of glass fiber yarn and glass fiber weft. The surfaces of the glass fiber yarn and the glass fiber weft the refractive indexes of which are close to the refractive index of resin are uniformly provided with impregnating compound layer, the main characteristic is that the glass fiber yarn and the glass fiber weft are multi-beam glass fiber twisted yarn. The utility model is characterized in that the tension intensity and the shearing strength are high, the joint force with the resin layer is strong, the producing cost is relatively low, and the fiber glass reinforced plastics piece which is made by the utility model is clear and transparent and the like. The utility model is especially applicable to prepare surfboard and flipper of water sports equipment which is made of fiber glass reinforced plastics.

Description

Glass fiber machine is weaved cotton cloth

Technical field

The utility model relates to a kind of glass fiber machine weaves cotton cloth, and belongs to fiberglass product reinforcing material technology, perhaps belongs to through compiling the Woven glass cloth technology.

Background technology

The utility model is mainly with the fiberglass product of doing light transmittance (transparent) is had higher requirements, for example the enhancing base material of fiberglass products such as aquatic sports equipment surfboard and fin thereof.

The used glass fiber machine of prior art clear glass steelwork is weaved cotton cloth, and is by the woven cloth of electron pole glass fibre, and it is made to flood sizing agent again by destarch.The purpose of its dipping sizing agent is, makes by the glass fiber machine of dipping sizing agent and weaves cotton cloth, and can be good at a layer access node with resin and lumps together.The glass fiber machine that adopts prior art to make is weaved cotton cloth, exist surperficial degree of purity poor, the sizing agent skewness, resin impregnated speed is slow, layer access node made a concerted effort, and poor and manufactured goods are not as clear as crystal to be waited not enoughly, and the physical property to glass fiber reinforced plastics product causes many harmful effects thus, simultaneously because also more complicated of its preparation technology, equipment investment and labour cost are higher, thereby its production cost is higher.

Summary of the invention

The purpose of this utility model is, provide a kind of surperficial degree of purity good, sizing agent is evenly distributed, strong with resin bed access node power, production cost is lower, weave cotton cloth with the glass fiber machine that its glass fiber reinforced plastics product of producing is as clear as crystal, to overcome the deficiency of prior art, satisfy the requirement that has the glass fiber reinforced plastics product of specific (special) requirements to produce to light transmittance.

The utility model realizes that the technical scheme of its purpose is:

A kind of glass fiber machine is weaved cotton cloth, and is interweaved by glass warp thread and glass weft yarn and forms, and its innovative point is: the surface in that index of refraction approaches the glass warp thread and the glass weft yarn of resin index of refraction is equipped with the sizing agent layer; Glass warp thread and glass weft yarn are multi beam glass folded yarn.

Can understand that by above given technical scheme the utility model is because the glass warp thread that it adopted and the index of refraction of glass weft yarn approach the resin index of refraction, so its fiberglass product of making is as clear as crystal.That is to say that the used glass of the utility model is transparent, this glass transparent and the preimpregnation sizing agent can be provided by U.S. PPG company and AGY company.The utility model is owing to adopt the glass of preimpregnation sizing agent simultaneously, and therefore, sizing agent is evenly distributed, and the glass fiber machine of making is weaved cotton cloth, and does not need destarch again and dipping sizing agent, thereby can save equipment investment and labour cost, reduces its production cost.Especially because warp thread of the present utility model and weft yarn, employing be the folded yarn of multi beam glass, thereby its tensile strength and shearing strength all are significantly improved, this is very favorable to goods fiberglass product, thereby has realized the purpose of this utility model.

Further innovative point of the present utility model is:

The preferred sizing agent layer of the utility model is a silane coupling agent layer.Certainly be not limited to this.Other can promote resin to combine with glass and have the sizing agent that enough layer access nodes close intensity all to be fine.

The twist of described glass warp thread and glass weft yarn multi beam glass folded yarn is between 28～100 sth. made by twisting/rice.This is that the utility model institute is preferred.It is fit to do the enhancing base material of sports equipment on the glass fiber reinforced plastic water.

The density of glass warp thread is in 7～8 pieces/centimeter scopes, and the density of glass weft yarn is in 9～10 pieces/centimeter scopes, and its fabric weight is at 135g～200g/m ²In the scope.This is that the utility model institute is preferred, described through weft count and grammes per square metre, can satisfy the requirement of sports equipment preparation on the glass fiber reinforced plastic water.

After technique scheme was implemented, the tension that the utility model had, shearing strength height were made a concerted effort by force with the resin bed access node, and production cost is lower, with characteristics such as its fiberglass product of producing are as clear as crystal, were conspicuous

Description of drawings

Fig. 1 is the structural representation of a kind of specific embodiment of the utility model;

Fig. 2 is the A-A profile of Fig. 1.

The specific embodiment

Shown in attached Fig. 1 and 2.A kind of main glass fiber machine with the fiberglass product enhancing base material of doing light transmittance is had higher requirements is weaved cotton cloth, interweave by glass warp thread 1 and glass weft yarn 2 and to form, fabric construction is a plain weave structure, surface in that index of refraction approaches the glass warp thread 1 and the glass weft yarn 2 of resin index of refraction is equipped with sizing agent layer 3; Glass warp thread 1 and glass weft yarn 2 are 4 bundle glass folded yarns.Described sizing agent layer 3 is silane coupling agent layers.Described glass warp thread 1 and glass weft yarn 2 are that the twist of 4 bundle glass folded yarns is 80 sth. made by twisting/rice.The density of glass warp thread 1 is in 7～8 pieces/centimeter scopes, and the density of glass weft yarn 2 is in 9～10 pieces/centimeter scopes, and its fabric weight is 150g/m ²

Weaving process of the present utility model can be finished by air-jet loom/arrow shaft loom.Its glass warp thread adopts 36 Tekes glasses, and glass weft yarn 2 adopts 68 Tekes glasses.

The utility model first sample is very successful.
