How important is the flexural strength of epoxy glass fiber wound tubes?

   Is there any relationship between the flexural strength of the epoxy glass fiber wound tube and the glass fiber content?

   Under the condition that other influencing factors are not considered, with the increase of the glass fiber content, the bending strength of the epoxy glass fiber wound tube increases rapidly at the beginning, and when the content of the glass fiber reaches a certain value, if it continues to increase The glass fiber content, the bending strength of the epoxy glass fiber wound tube will be rapidly reduced. At this time, the value of the bending strength of the epoxy glass fiber wound tube is the maximum value that can be achieved under the process conditions.

     The epoxy glass fiber winding tube is obtained by impregnating a glass fiber (wire or cloth tape) conforming to a certain standard with an epoxy glue, and continuously winding on the core mold under specific process conditions, through curing, demoulding and post-processing. And a composite product obtained.

     Due to the excellent properties of such composite products in terms of insulation, mechanical strength, density, etc., the power industry often makes hollow composite insulators widely used in electrical equipment such as transformers, surge arresters, and transformers.

     Bending strength is an important index for the strict control of epoxy glass fiber wound pipe in the production and application of electrical equipment. In general, in the production process of epoxy glass fiber wound pipe, the selection of each component of epoxy glue It has an influence on the ratio, the quality of the glass fiber and the post-treatment method, the winding process conditions, and the content of the glass fiber. Through experiments, we mainly studied the relationship between the glass fiber content in the epoxy glass fiber wound tube and the vertical layer bending strength of the epoxy glass fiber wound tube.

    In fact, there are many factors affecting the flexural strength of the epoxy glass fiber wound tube. In addition to the content of the glass fiber, the specification, quality and post-treatment method of the glass fiber, the selection and ratio of the components of the epoxy glue, the winding and curing Process condition control, etc. are also very important factors.

      In order to produce high-performance epoxy glass fiber wound pipe which is widely used in the electrical industry with bending strength in accordance with national standards, the bending strength of the epoxy glass fiber wound pipe should be made on the basis of comprehensive consideration of various influencing factors.

    Zhejiang Yingtai Insulation Materials Co., Ltd. customizes epoxy fiberglass winding tubes with different bending strengths according to customers' requirements to meet various specifications of various colors and various sizes.
