Embodiment Construction
[0041] Please refer to figure 1 , which is a manufacturing process method step of the all-polyester self-reinforced composite material of the present invention comprising:
[0042] Step 1. fiber cloth and resin preparation (10): the raw material of all-polyester composite material of the present invention comprises polyester fiber cloth and polyester resin, wherein:
[0043] (1) The polyester fiber cloth must first go through a heat-setting step, so that the subsequent manufacturing process that requires heating can maintain dimensional uniformity. In other words, after the selected polyester fiber cloth has undergone a heat-setting step at a specific temperature, the The polyester fiber cloth can maintain a stable and small size range in the subsequent heating and cooling process;
[0044] (2) The polyester resin must first be modified to lower the melting point of the polyester resin, thereby causing a temperature difference between the selected polyester resin and the melt...

Abstract
The invention relates to an all-polyester self-enhanced composite material, a preparation method and applications thereof. The invention relates to a single-layer all-polyester composite material which comprises a polyester fiber fabric, and a membrane-shaped low-melting point polyester resin tightly coating the polyester fiber fabric; the melting point of the low-melting point polyester resin is lower than that of the polyester fiber fabric, wherein the preparation method of the single-layer all-polyester composite material comprises the steps as follows: thermal shaping and manufacturing process is implemented on the polyester fiber fabric; the polyester resin is modified so as to lower the melting point and form the membrane-shaped low-melting point polyester resin; the differences between the melting points of the modified low-melting point polyester resin and the polyester fiber fabric form a working temperature window; the polyester fiber fabric and the low-melting point polyester resin are overlapped; moreover, the polyester fiber fabric and the low-melting point polyester are combined to form the single-layer all-polyester composite material through a thermal pressing manufacture process in the working temperature window.
Description
technical field [0001] The invention relates to a composite material, in particular to an all-polyester composite material, its manufacturing process and its application. Background technique [0002] Traditional composite materials have the characteristics of light weight and high strength, so they are the best choice for many occasions with special needs. However, the current composite materials are limited by many factors such as price, non-recyclability, mostly thermosetting materials, and poor composite properties of heterogeneous material interfaces, which restrict their application. [0003] Composite material expert Pegoretti (2007) pointed out in his article on the future trend of composite materials that the era of environmental protection and energy saving has come, and the development of methods for recycling and reusing materials should have new thinking and practices, while single polymer composites (Single Polymer Composite, SPC for short) is a very important...
