Polymer/short fiber composites fabricated by direct fiber feeding injection molding

Xiaofei Yan, Hua Shen, Guangbiao Xu, and Shengbin Cao
23 April 2018
Direct fiber feeding injection molding is an effective way of improving the mechanical properties of polymer/short fiber composites by enhancing the fiber length.

Predicting the fiber-breakage history in injection molding

Chao-Tsai Huang
3 April 2018
Simulations of the injection-molding process for long-fiber-reinforced thermoplastics enable the prediction of complex fiber behavior and can therefore be used to investigate the effect of screw type.

31 October 2017
Conventional fiber-length measurement techniques for discontinuous fiber-reinforced composites are evaluated and a novel characterization methodology is proposed.

Flexible insert for microinjection compression molding of polymer microlens arrays

Han-Xiong Huang, Heng Xie, and An-Fu Chen
18 September 2017
A new method of microinjection molding, based on the use of a flexible insert combined with a porous plate, enables the fast and efficient fabrication of polymer microlens arrays with tunable heights.

Rapid fabrication of various molds for polymer lens arrays

Chih-Yuan Chang
22 June 2017
A one-step method enables the fabrication of molds with concave lens array patterns, which can be used for the replication of polymer lens arrays.

Relating mold adhesion problems to heat transfer properties

Daniel Treffer, Alexander Troiss, and Johannes Khinast
22 February 2017
Interfacial temperature instantaneously approaches a certain level depending on thermal effusivities when two bodies are brought into contact, and this level is decisive for adhesion formation.

Effects of tempering on adhesion of liquid silicone rubber to thermoplastics

Christin Baumgart, Volker Altstädt, and Dominik Weiß
20 February 2017
Tempering improves the mechanical properties of liquid silicone rubber, but also decreases its ability to adhere to engineering thermoplastics.
