Preferred epoxy resins include bisphenol-A based epoxy resins and epoxy cresol novolac resins. A preferred oxide of titanium is titanium dioxide. [0048] 5. The electrostatic powder coating method begins when the powder in the apparatus holding tank is mixed with compressed air, which enables the...
Typical materials used in SLA are acrylic and epoxy resins. Figure 18. Concept scheme of SLA technology [70]. The main variable parameters in this technology are laser power, layer thickness, exposure time at each point, and scanning speed. This method can be used to obtain various ...
In order to fabricate new types of materials as an alternative to conventional materials in aerospace, there are some issues that need to be addressed such as high conductivity, low weight, eco-friendliness, flexible manufacturability, high mechanical strength, and ease of repair [60]. 4.11. ...
