New Fiber Reinforced LCP Compounds for Injection Molding

Technical Classification:
[ Products / Processed Products ]
[ Carbon fibers ] [ glass fibers ] [ injection molding ] [ LCP ] [ liquid crystal polymers ] [ pellets ]

Point of the Proposed Technology

We have succeeded in developing two types of pellets for melt molding with mechanical properties comparable to that of metal materials; one with high stiffness, and the other with high impact strength by significantly improving the conventional short fiber-reinforced LCP compounding technology and injection molding technology in order to maximize the performance of liquid crystal polymers (LCP) and reinforcement fibers. The two types of pellets are expected to not only meet light-weight needs of automobile components, etc. but also contribute to creation of new added values.


・ Realization of thin walls and light weight in members
・ Reduction of processing time and processing costs
・ Realization of reduction of the number of components and complicated shapes

Conventional Technology

[Conventional long fiber compounds]
・No significant improvement of mechanical properties is observed by the introduction of long fibers in terms of strength, elastic modulus, and impact strength.
・ It is difficult to achieve physical properties equivalent to those of press, formed products (BMC, SMC, etc.) and metal materials.
