Abstract
Multiaxially oriented laminates comprised of substantially uniaxially oriented sheets of liquid crystal polymers and a method of production thereof are provided which exhibit desirable mechanical properties and good thermal and chemical resistance. The sheets which comprise the laminate are thermally bonded together and oriented at an angle to one another to provide the multiaxially oriented laminate. The mechanical properties of the laminate can be adapted for specific applications by adjustment of the number, thickness and angle of orientation of each sheet.
Claims38
A method of providing a laminate which exhibits multiaxial orientation, possesses desirable mechanical properties and excellent thermal and chemical resistance comprising:
- (a) providing at least two sheets comprised of a substantially unidirectionally oriented polymer which is capable of forming an anisotropic melt phase;
- and
- (b) subjecting said at least two sheets to thermal bonding conditions, the longitudinal axis of said sheets being oriented at an angle to each other so as to provide a laminate possessing multiaxial orientation comprised of said at least two sheets while retaining substantial uniaxial orientation within said sheets.
A laminate which exhibits multiaxial orientation, possesses desirable mechanical properties and desirable thermal and chemical resistance comprised of at least two sheets of a substantially unidirectionally oriented polymer which is capable of forming an anisotropic melt phase, said at least two sheets being thermally bonded together and oriented at an angle with respect to one another.
