Abstract:
A method for manufacturing an electronic parts case using biocomposites reinforced with sea algae fibers is provided to prevent an electronic parts case from being detached together with electronic parts by reducing the thermal expansion coefficient of the electronic parts case. A method for manufacturing an electronic parts case using biocomposites reinforced with sea algae fibers comprises the steps of drying sea algae fibers(S100), shattering the dried sea algae fibers(S101), and drying, shattering and dissociating the sea algae fibers into fine fibers(S102). Polymer specimen is dried to remove moisture therefrom(S200). Polymer specimen including biodegradable and general polymer is fragmentated in the form of powder(S201). The sea algae fibers are mixed with the dried polymer powder to produce an integrated mixture thereof(S300). The mixture is filled in a metal mold(S400). The metal mold is compressed at the high temperature to form a case(S500).
Abstract:
A bio-composite material, and a method for preparing the bio-composite material are provided to improve thermal properties and mechanical properties by enhancing the dispersion of a red alga fiber reinforcing material. A bio-composite material is prepared by using the fiber extracted from red alga. Preferably the fiber extracted from red alga is bleached, has the thermal stability more excellent than that of cellulose and has the crystallinity similar to that of cellulose. The bio-composite material is prepared by (S100) drying a red alga fiber; (S101) pulverizing the dried fiber; (S102) drying, pulverizing and dissociating the obtained red alga fiber; (S200) drying a polymer to remove moisture; (S201) pulverizing the dried polymer to obtain a polymer powder; (S300) mixing the red alga fiber and the polymer powder; (S400) coating the mixture in a metal mold; and (S500) compression molding it.
