摘要:
The invention aims to provide a polylactic acid based resin sheet that is high in impact resistance, transparency, slipperiness, and creasability, and suitable particularly for production of moldings. This aim is met by a polylactic acid based resin sheet comprising polylactic acid and rubber particles and characterized by meeting requirements 1 to 3 listed below: Requirement 1 "0.01 µm ≤ |Ra1 - Ra2| ≤ 0.2 µm", requirement 2 "Ra1 ≤ 0.3 µ m", and requirement 3 "Ra2 ≤ 0.3 µm", where Ra1 is the two-dimensional center line average roughness of one of the faces of the sheet, and Ra2 is the two-dimensional center line average roughness of the surface other than that subjected to measurement of Ra1.

The present invention provides an excellent structural material for movable equipment, structural members for building materials, electronic and electrical equipment and the like by bonding an ordinary steel material and an FRP prepreg strongly to each other to facilitate mechanical joining and disassembly using bolts and nuts or the like. It has been found that a steel material having surface configuration with specifically determined ultra-fine irregularities is compatible with an epoxy resin adhesive and exhibits thus strong adhesion. This technique can be utilized to produce a composite component 26 that comprises steel plates 28, as a cover material, integrated with FRP 27. The composite component can be assembled with other metallic members through fastening using bolts 30. Also, structural members having the FRP 27 in the main structure and the steel material at the ends can be easily produced by virtue of the above strong adhesion.

Partially expanded closed-cell unmatured polystyrene bead with a partial vacuum within the cells inside the bead, which may be coated with an air impervious coating to retain a partial vacuum inside cells for a prolonged period of time. The resulting bead has improved thermal insulating properties and may be used for insulation.

Bei einem Bodenbelag, der aus mindestens einer Schicht aus einem thermoplastischen Material besteht, sind gemäß der Erfindung Abschnitte der Oberfläche des Bodenbelages aus einem Naturmaterial, wobei diese Abschnitte jeweils zueinander mit Abstand oder jeweils aneinander anliegend angeordnet sind. Durch die Wärmeeinwirkung beim Herstellen des Bodenbelages wird das Naturmaterial integral mit dem thermoplastischen Material und von der Unterseite von dem thermoplastischen Material benetzt.

The objective of the invention is to solve the problems described above. Specifically, the invention aims to provide highly heat resistant and dimensionally stable polyester film that is so high in formability as to maintain a low stress and a high ductility during forming processes. The invention provides a polyester film comprising ethylene glycol component that accounts for 60 mol% or more of the glycol components in the polyester film, containing a crystal nucleating agent up to 0.01 to 5 mass% relative to the entire polyester film that accounts for 100 mass%, and having a crystal melting energy, ΔHm, of 5 to 35 J/g.
